DeMaria et al. 201028 reported results as 0-3m, 3-6m, 6-12m,12-24m. The range 6-12m was reported in the 6-11m category, 12-24m was reported in the >=12mth category.

Serrot, 2011 (6027) only reported median and IQR. Median value used instead of mean for summary calculations.

Scopinaro et al. 200149 reports data for obese and overweight patients separately, both subgroups contribute to this analysis but it is only counted as 1 study/article.
