¹ Scocco et al. (2006): controls received intervention from week 9-24; results presented are the results after 8 weeks

² Mauri et al. (2008): controls received intervention from week 12-24; results presented are the results after 12 weeks

³ Kwon et al. (2006): no information on baseline and endpoint weight, only on changes in weight

⁴ Brar et al. (2005): no information on baseline and endpoint BMI, only on changes in BMI

* significant difference in weight or BMI change from baseline to endpoint in intervention groups (p < .001)

** significant difference in weight or BMI change from baseline to endpoint in intervention groups (p < .05)

Abbreviations: kg = kilogramme; BMI = Body Mass Index; NS = not significant; NI = no information on significance
