The fresh difference out-of undesirable pregnancy prevalence inside for each and every article try computed in accordance with the binomial shipment algorithm by extracting the new regularity sample proportions out of wrote analysis. Heterogeneity is actually reviewed by using the Cochran’s Q make sure new We dos statistic, and you will according to thinking obtained, the fresh haphazard consequences design was applied to mix the studies and estimate the newest pooled prevalence. The new heterogeneities of the training was basically split up into; lower than twenty-five{e14227831907abd58a3701be0558a09aa81b41d303677f96820999336e721318} (lowest heterogeneity), 25–75{e14227831907abd58a3701be0558a09aa81b41d303677f96820999336e721318} (moderate heterogeneity) and more than 75{e14227831907abd58a3701be0558a09aa81b41d303677f96820999336e721318} (high heterogeneity) . We plus assessed the frequency regarding undesirable pregnancy from the area, article’s vocabulary, and you can methodological quality. Harness area in accordance with the Egger’s decide to try was used to look at book prejudice.

The full attempt dimensions was 16,298 (M = 815), and you will decide to try dimensions ranged off 100 to help you 5152. seven posts were for the Persian and you can thirteen when you look at the English. With regards to methodological quality, 8 education got a negative top quality [17,18,19,20,21,twenty two,23,24] and you will 12 got the common quality [5, ten,11,twelve, twenty five,twenty-six,twenty seven,28,31,31,31,32]. The fresh new breakdown of selected stuff try presented for the Table 1.
