Abstract We submit a letter to the editor regarding “Interventioneffects of a kindergarten-based health promotion programme on obesity related behavioural outcomes and BMI percentiles” by Kobel et al. becauseof 4 issues: 1) clustering is ignored in the analysis, 2) outcomes wereswitched compared to the preregistration, 3) there is spin in theabstract, and 4) concerns about the self-reported outcomes. We believethat reanalysis of the results is necessary as accounting for clusteringmay change the conclusions of the study.
