Templated review frame. This review question was generated by crossing an indication with a compound for which contributing trials exist. Its prose frame is templated and is shared with other questions of the same shape. Its included studies, its summary of findings and its certainty rating are computed from the underlying records and are not templated. The Institute publishes these questions because the alternative is to leave a question the document set can answer unanswered, and it labels them because the alternative is to present a templated frame as an authored one.

§3Included and excluded studies

Every study contributing to this review is listed below with the data extracted from it. The extraction table is published at the level of the individual outcome and study so that the synthesis can be checked without the reader having to retrieve each source.

§3.1Included studies

Table 4. Included studies with the characteristics extracted from each.

3 included studies. Each links to its structured abstract, which carries a field-by-field provenance table distinguishing extracted figures from Institute reconstructions.

Contributing participants across studies reporting a randomised total: 1,050. Studies for which the Institute does not hold a randomised total contribute to the qualitative synthesis and not to any pooled figure.

§3.2Excluded at full text, with reasons

Table 5. Reports excluded at full text, by reason. A review that reports an exclusion count without reasons cannot be checked against its own protocol.

Reason for exclusionReports
Not a randomised comparison3
Population outside the review question4
Intervention outside the review question4
Comparator not eligible5
No eligible outcome reported6
Duplicate report of an included study6
Conference abstract without extractable data2
Retracted or subject to an expression of concern2
22 reports excluded at full text in total.

Judgements are the Institute's own and are recorded per outcome. A study may carry a different judgement in a different review that assesses a different outcome from it.
