Trial characteristics	Description/Detail from report
15. How many participants were randomized in the trial?
16. State the title/name given to each randomly allocated treatment group by investigators/authors of the trial (use direct quotes) and the number of participants in each group
17. Number of participants in each group who received the intended treatment
18. Number of participants reported in the analysis for each outcome (Provide details of any differences in numbers of participants between intended and actual analysis of outcomes)
19. Number of excluded participants (i.e. investigators/trialists withdrew participants from trial after randomization and group allocation. Report numbers, %, etc., and study author’s rationale for exclusion)
20. Number of drop‐outs or loss to follow‐up (participants who intentionally or unintentionally withdrew from the trial after treatment allocation. Report numbers, %, etc., and rationale if provided)
21. Length of follow‐up reported in the trial
22. Duration of the trial (i.e. from first to last participant)
23. Describe the positioning schedule and/or sequence for each allocated treatment group (e.g. group 1 ‐ 2‐hourly lateral positioning vs group 2 ‐ supine positioning (parallel‐group design) or randomized sequence of SLR for all participants serving as own controls with 6 possible combinations of SLR (cross‐over design). Report on the following · duration in each body position, including baseline position · total number of turns undertaken by participants in each group during the trial · total duration of the positioning schedule (from baseline/first position to last measurement in the last position). If cross‐over design, give duration in each arm and total duration
