“…With regards to the number of sexual partners, participants who had multiple sexual partners were found to have increased odds of experiencing repeat-induced abortion compared with those who had a single sexual partner (OR = 6.28, 95% CI 4.28, 9.22) with low heterogeneity between the included studies (I 2 = 3.6%, p = 0.375). Four, studies were used to determine the association between having multiple sexual partners and the risk of experiencing repeat-induced abortion [ 23 , 24 , 25 , 27 ]. However, a statistically significant association was not found between ever use of family planning and repeat-induced abortion by using two primary studies [ 23 , 27 ] (OR = 1.03, 95%, CI 0.09, 11.59) with high heterogeneity between the included studies (I 2 = 93.0%, p < 0.001) ( Figure 6 ).…”
