Reaching a consensus on a patellofemoral pain syndrome self-management programme for recreational cyclists in Saudi Arabia: A modified Delphi study.

No patients took part and the programme was never tried out. The authors themselves say it remains a theoretical model that needs real-world testing for feasibility, acceptability and effectiveness. It is expert opinion throughout, and the paper says so: reliance on expert opinion introduces potential bias, and the panel size limits how far the findings can be generalised. The panel came out smaller and more regional than planned. Recruitment started with experts from 10 countries but a low response rate shifted it to five, which the authors say may have reduced the diversity of perspectives. The panel was narrow in other ways: 22 of the 25 were physiotherapists and 21 of the 25 were men, and nearly half had less than 5 years' experience working with cyclists. Six of the 25 experts dropped out before round two, and round two is where several new items were rated for the first time. The agreement threshold is stated as 70% in the analysis section, but the results describe consensus as 90% or more, so it is not always clear which threshold a given item was measured against. The 11 items added in round two were shaped by the researchers from the panel's comments and were rated only once, so they had no first-round test.

The paper states the research received no specific grant from any funding agency in the public, commercial or not-for-profit sectors. Participants took part voluntarily and were offered no financial or material incentives. No separate conflict of interest statement appears in the text supplied.

Do not read this as evidence that the programme works. No patient has used it and no outcome was measured. It was also built around Saudi conditions with a panel drawn from five countries, so treat the Arabic-language, prayer-time and extreme-heat components as specific to that setting rather than a programme you can adopt unchanged.
