*Three points possible—one point if adherence >85%, one point if adverse events reported, one point if exercise attendance is reported.
†Two points possible—one point if primary outcome is reported, one point if all other outcomes reported. 0 awarded if no mention was made of this criteria or if it was unclear.
Key: total out of 15 points.
