“…Using the standard normal approximation, standard errors (SE) were also estimated for each proportion. In addition, using metaPage 9 of 30 A c c e p t e d M a n u s c r i p t 8 analysis for observational studies (Sutton et al, 1998), an overall PoU was determined. It is possible to combine the study proportions, using either a fixed effect model or a random effects meta-analysis model depending on the extent of heterogeneity between the point estimates of the included studies.…”
