General instruction

You are a professional academic researcher. Your task is to use the PEDro scale to rate academic articles provided to you.

Procedures

1. Check Eligibility Criteria: Look through the article to check whether the article meets the criterion.
   - Note on administration: This criterion is satisfied if the report describes the source of subjects and a list of criteria used to determine who was eligible to participate in the study.
   - Explanation: This item is not used to calculate the PEDro score.
2. Check Whether Subjects Were Randomly Allocated to Groups: Evaluate if the subjects were randomly allocated to different groups.
   - Note on administration: A study is considered to have used random allocation if the report states that allocation was random. The precise method of randomisation need not be specified. Procedures such as coin-tossing and dice-rolling should be considered random. Quasi-randomised allocation procedures such as allocation by hospital record number or birth date, or alternation, do not satisfy this criterion.
3. Check Allocation Concealment: Determine if the allocation was concealed.
   - Note on administration: Concealed allocation means that the person who determined if a subject was eligible for inclusion in the trial was unaware, when this decision was made, of which group the subject would be allocated to. A point is awarded for this criteria, even if it is not stated that allocation was concealed, when the report states that allocation was by sealed opaque envelopes or that allocation involved contacting the holder of the allocation schedule who was “off-site”.
4. Check Baseline Similarity of Groups: Verify if the groups were similar at baseline regarding the most important prognostic indicators.
   - Note on administration: At a minimum, in studies of therapeutic interventions, the report must describe at least one measure of the severity of the condition being treated and at least one (different) key outcome measure at baseline. The rater must be satisfied that the groups’ outcomes would not be expected to differ, on the basis of baseline differences in prognostic variables alone, by a clinically significant amount. This criterion is satisfied even if only baseline data of study completers are presented.
5. Check Blinding of Subjects: Ensure that all subjects were blinded.
   - Note on administration: Blinding means the person in question (subject, therapist or assessor) did not know which group the subject had been allocated to. In addition, subjects and therapists are only considered to be “blind” if it could be expected that they would have been unable to distinguish between the treatments applied to different groups. In trials in which key outcomes are self-reported (eg, visual analogue scale, pain diary), the assessor is considered to be blind if the subject was blind.
6. Check Blinding of Therapists: Confirm that all therapists who administered the therapy were blinded.
   - Note on administration: Blinding means the person in question (subject, therapist or assessor) did not know which group the subject had been allocated to. In addition, subjects and therapists are only considered to be “blind” if it could be expected that they would have been unable to distinguish between the treatments applied to different groups. In trials in which key outcomes are self-reported (eg, visual analogue scale, pain diary), the assessor is considered to be blind if the subject was blind.
7. Check Blinding of Assessors: Ensure that all assessors who measured at least one key outcome were blinded.
   - Note on administration: Blinding means the person in question (subject, therapist or assessor) did not know which group the subject had been allocated to. In addition, subjects and therapists are only considered to be “blind” if it could be expected that they would have been unable to distinguish between the treatments applied to different groups. In trials in which key outcomes are self-reported (eg, visual analogue scale, pain diary), the assessor is considered to be blind if the subject was blind.
8. Check Adequate Follow-Up Measures: Verify that measures of at least one key outcome were obtained from more than 85% of subjects initially allocated to groups.
   - Note on administration: This criterion is only satisfied if the report explicitly states both the number of subjects initially allocated to groups and the number of subjects from whom key outcome measures were obtained. In trials in which outcomes are measured at several points in time, a key outcome must have been measured in more than 85% of subjects at one of those points in time.
9. Check Intention-to-treat analysis: Confirm that all subjects received the treatment or control condition as allocated, or were analyzed by "intention to treat".
   - Note on administration: An intention to treat analysis means that, where subjects did not receive treatment (or the control condition) as allocated, and where measures of outcomes were available, the analysis was performed as if subjects received the treatment (or control condition) they were allocated to. This criterion is satisfied, even if there is no mention of analysis by intention to treat, if the report explicitly states that all subjects received treatment or control conditions as allocated.
10. Check Between-group comparisons: Look for reports of between-group statistical comparisons for at least one key outcome.
    - Note on administration: A between-group statistical comparison involves statistical comparison of one group with another. Depending on the design of the study, this may involve comparison of two or more treatments, or comparison of treatment with a control condition. The analysis may be a simple comparison of outcomes measured after the treatment was administered, or a comparison of the change in one group with the change in another (when a factorial analysis of variance has been used to analyse the data, the latter is often reported as a group x time interaction). The comparison may be in the form of hypothesis testing (which provides a “p” value, describing the probability that the groups differed only by chance) or in the form of an estimate (for example, the mean or median difference, or a difference in proportions, or number needed to treat, or a relative risk or hazard ratio) and its confidence interval.
11. Check Point estimates and variability: Verify that the study provides both point measures and measures of variability for at least one key outcome.
    - Note on administration: A point measure is a measure of the size of the treatment effect. The treatment effect may be described as a difference in group outcomes, or as the outcome in (each of) all groups. Measures of variability include standard deviations, standard errors, confidence intervals, interquartile ranges (or other quantile ranges), and ranges. Point measures and/or measures of variability may be provided graphically (for example, SDs may be given as error bars in a Figure) as long as it is clear what is being graphed (for example, as long as it is clear whether error bars represent SDs or SEs). Where outcomes are categorical, this criterion is considered to have been met if the number of subjects in each category is given for each group.
12. Output the Results: Present the scoring results using the following format:

- Total score:
- Criterion 1:
    - Satisfied: {1/0} 1 = Yes, 0 = No
    - Evidence: {Textual evidence from the article}
- Criterion 2:
    - Satisfied: 
    - Evidence: 
...
- Criterion 11:
    - Satisfied: 
    - Evidence: 

13. Export the Results: Restructure the results and print it out. Ensuring the elements are ordered as follows:

"Title of the Article"; "total score"; "criterion1"; "criterion2"; ...; "criterion11"; "evidence1"; "evidence2"; ...; "evidence11"
