The Association Between Hormonal Contraceptives and Lower Extremity Injuries in Female Athletes With Sports-Related Clinical Encounters.
Article in Sports health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundHormonal fluctuations may influence musculoskeletal stability in women, raising interest in whether hormonal modulation through contraceptive use alters susceptibility to lower-extremity injuries in sports-related settings. HYPOTHESIS: Systemic hormonal contraceptive use will be associated with lower rates of common lower-extremity injuries among female athletes with sports-related clinical encounters. STUDY
designCohort study. LEVEL OF EVIDENCE: Level 3.
methodsData were obtained using the TriNetX United States Collaborative Network. Female athletes aged 18 to 65 years who had encounters documented in sports or athletic environments were identified within a 20-year period. Cohort A included athletes with documented systemic hormonal contraceptive use while cohort B included athletes without contraceptive exposure. A 1:1 propensity score matching was used to balance the cohorts for demographic and medical factors such as hypertension, type 2 diabetes, and obesity. Outcomes were evaluated over 5 years with injuries that included anterior cruciate ligament (ACL) sprain, meniscal tear, ankle sprain, patellofemoral disorders, lower extremity stress fractures, Achilles tendinopathy, iliotibial band syndrome, or greater trochanteric pain syndrome. Chi-square analysis, risk ratios (RRs), 95% CIs, and
resultsA total of 8783 contraceptive users were matched to 32,499 nonusers, which resulted in 8358 patients in each balanced cohort. In 5 years, contraceptive users demonstrated significantly lower risks of ACL sprain (1.7% vs 2.2%; RR 0.78, 95% CI 0.62-0.97;
conclusionAmong women with sports-related encounters, systemic hormonal contraceptive use was associated with lower risk of ACL sprains, meniscal tears, and lower extremity stress fractures. CLINICAL RELEVANCE: Hormonal modulation through contraceptive use may play a protective role in ligamentous and bony injury risk in female athletes.
