The full test size is sixteen,298 (Meters = 815), and you will attempt proportions ranged off a hundred so you can 5152. seven blogs were in Persian and you can thirteen inside the English. In terms of methodological quality, 8 studies got a bad top quality [17,18,19,20,21,twenty-two,23,24] and you will several had an average quality [5, 10,eleven,several, 25,twenty six,twenty-seven,28,31,31,30,32]. The newest description of your chose articles is demonstrated in the Dining table 1.
The overall frequency of unwelcome maternity certainly one of Iranian people are 26% (95% Depend on Interval [CI]: 23–28) (Fig. 2).

The diamond shown at the end of shape means the new lbs of squares. The fresh horizontal diameter of diamond reveals the fresh new you’ll a number of frequency result. A couple of vertical contours are shown about shape. New dotted vertical range that is in accordance with the diamond vertical axis suggests all round meta-study benefit (pooled frequency). Prevalence of unwelcome pregnancy and its own 95% count on period certainly one of Iranian lady according to title out of very first writer and you will year away from investigation utilising the haphazard consequences model. The center section of every line portion suggests new prevalence out of undesired pregnancy from inside the per study, therefore the diamond reveals all round prevalence out-of unwanted pregnancy
