Contraception use and changes in young women with newly diagnosed breast cancer.
Trial report in Fertility and sterility, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT01647607 (Young and Strong), which is not on this map. Cited by 1 paper.
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.

Abstract
objectiveTo evaluate contraception use and change among young women with early breast cancer.
designSecondary analysis of a cluster randomized trial. SUBJECTS: Patients with newly diagnosed breast cancer age ≤45 years enrolled from 54 US oncology practices.
interventionSites were randomly assigned to the Young Women's Intervention, an educational intervention for young women with newly diagnosed breast cancer and their oncologists addressing issues specific to this population, including contraception, or a contact-time control physical activity intervention. Participants completed surveys in follow-up, including a 3-month survey regarding contraceptive practices before and after diagnosis.
main outcome measuresOutcomes of interest included young women's contraceptive use and methods before breast cancer diagnosis and 3 months after study enrollment. Logistic regression models assessed factors associated with use of less than highly effective contraceptive methods categorized according to World Health Organization effectiveness tiers and changes in contraceptive methods.
resultsOf 312 women included, 258 (83%) reported contraceptive use before breast cancer diagnosis, and 275 (88%) reported contraceptive use after diagnosis. Use of highly effective methods (e.g., vasectomy, non-hormonal intrauterine devices) increased from 39% before diagnosis to 52% after diagnosis. Use of moderately effective methods (e.g., hormonal methods) decreased from 22% before diagnosis to 3% after diagnosis. Use of less effective methods (e.g., condoms, withdrawal) increased from 22% before diagnosis to 34% after diagnosis. On multivariable analysis, factors associated with using less than highly effective contraception after diagnosis included desire for additional children (odds ratio [OR], 6.33; 95% confidence interval [CI], 3.76-10.66) and discussing contraception with a provider (OR, 1.96; 95% CI, 1.12-3.40). After breast cancer diagnosis, 207 patients (66%) reported no change in contraceptive methods. On multivariable analysis, factors associated with contraceptive method change after diagnosis included age <35 years (OR, 2.96; 95% CI, 1.57-5.58) and provider discussion (OR, 3.59; 95% CI, 1.91-6.78). There was no association in either analysis with study arm.
conclusionAlthough most patients used contraception after breast cancer diagnosis, nearly half reported using less than highly effective contraceptive methods with higher failure rates, highlighting the need for early and improved contraceptive counseling for young women with breast cancer.
