a strong trendP =.06
Four studies that examined IWG had inconclusive results, showing nonsignificant differences between the baseline and follow-up period [ 33 ], a strong trend for relatively lower IWG ( P =.06) in the intervention groups during follow-up [ 16 ], a significant mean reduction in weight gain between the groups at the end of the study [ 26 ], and a superimposed linear regression of the reduction of average daily IWG for 1 participant during the follow-up in a case study [ 20 ].
