Interventions aimed at increasing the level of physical activity by including organised follow-up: a systematic review of effect

Table 2 Effect estimates for the comparisons concerning supervised group PA

Study	Outcome	Participants (studies)	Comparison	Effect measure	Follow-up period/s	Effect estimate	Quality of the documentation
Isaacs [17] Strength, fitness	Minutes of PA/week	305 (1)	Advice	% change from BL (95% CI)	Post-treatment	−13% (−29, 8)	Low^1,2

Park [18]	MET-adjusted minutes of PA/week	40 (1)	No treatment	Mean diff, p-value	Post-treatment	1050, ns	Very low^1,3

Legend: PA = physical activity; MET = metabolic equivalent of task, BL = baseline, ns = not significant; ¹unclear risk of bias at study level, ²only one study, ³only one small study.
