Heterogeneity is actually analyzed making use of the Cochran’s Q make sure the brand new We 2 fact, and you will depending on the opinions acquired, new random outcomes design was utilized 
to combine the studies and you may estimate the newest pooled prevalence.

I and additionally examined the newest incidence from undesirable maternity of the region, article’s code, and you can methodological top quality. Harness spot in accordance with the Egger’s sample was used to look at guide prejudice.
