These domains were: selection bias, study design, confounders, blinding, data collection methods, and withdrawals and dropouts.
This tool consists of six criteria: selection bias, study design, confounders, blinding, data collection methods, and withdrawals and dropouts.
It consists of six criteria: selection bias, allocation bias, control of confounders, blinding of outcome assessors, data collection methods, and withdrawals and dropouts.
18 Using the EPHPP tool, studies were assessed against six criteria: selection bias, design, confounders, blinding, data collection methods and withdrawals and dropouts.
EPHPP quality assessment involves rating each article on a three-point scale (strong, moderate and weak) in six components: selection bias, study design, confounders, blinding, data-collection methods, and withdrawals and drop-outs.
Quantitative studies most commonly received weak ratings for confounders, data collection methods and withdrawals and drop outs (see Tables 2 and 3 for further details on study quality assessments).
In this checklist, six items include selection bias, study design, confounder control, blinding, data collection method and withdrawals and dropouts during study execution.
Weibull regression models are estimated to analyze the determinants of all-method and withdrawal discontinuation and failure.
Overall, 19% and 28% of women became pregnant during the first year of using a contraceptive method and withdrawal, respectively.
Around 85% of all-method and withdrawal failures ended in abortion, accounting for 35.2% and 24.1%, respectively, of all abortions reported in the 1999 RRHS.
With regards to contraception, previous IUD use was found to slightly increase the risk of EP AORR = 1.72, 95%% CI: 1.39 2.13), while previous use of other contraceptive methods including condom, rhythm method and withdrawal method were shown to protect women from the incidence of EP (AOR = 0.56, 95%% CI: 0.47 0.66).
