1, study provided information on the quality item and met the criterion; 0, study provided information on the quality item but did not meet the criterion; ?,study provided no or insufficient information on the quality item.
I: informativeness; V: validity/P: precision. aattrition analyses were performed and results showed no significant differences between baseline study sample and population of eligible subjects; battrition analyses were performed and results showed no significant differences between dropouts and follow‒up participants; cassociated factors showed internal consistency of Cronbach's alpha ≥0.70 or test‒retest correlations of ≥0.80 or κ/ICC ≥0.70. For clinical factors a standardized protocol was followed by trained researchers; dassociated factors showed correlations of ≥0.80 or κ/ICC ≥0.70 with similar constructs. For physical variables (i.e., past physical activity and past sedentary behavior) an objective measurement instrument (i.e., accelerometer/pedometer) was used. For clinical variables a standardized protocol was followed by trained researchers; eFor walking interventions: adherence or maintenance was measured by accelerometer or pedometer read out by the researcher. For supervised exercise : the trainer reported presence of the participant; fthe number of items scored positively on the validity/precision (V/P) criteria divided by the total number of validity/precision criteria (i.e. 8).
