Eligible designs included clinical trials, cohort and case control studies, case series, case reports, and adverse event data. Two reviewers independently screened titles\/abstracts, reviewed full texts, selected studies, extracted data, and assessed bias (ROBINS-I: cohorts), methodological quality (Newcastle Ottawa: case-control), and critical appraisal (Joanna Briggs Institute: case series).

Evidence is very uncertain about their effects on preventing pregnancies, and safety related to ischemic cerebrovascular disease, myocardial infarction, venous thromboembolism, weight gain, hypertension, kidney function, and lipid profile. Similarly, the effects of progestin-only pills, injectables, and vaginal rings on cardiovascular and metabolic outcomes remain highly uncertain.
