Observational study in The European journal of contraception & reproductive health care : the official journal of the European Society of Contraception, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT01986439 (The Contraceptive Choice Project), which is not on this map.

1 · What the graph read from it

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 compare rates of dual method use (concurrent use of condoms and an effective method of contraception) in long-acting reversible contraceptive (LARC) and non-LARC hormonal contraceptive users, and to determine factors associated with dual method use.

methodsWe conducted a secondary analysis of the Contraceptive CHOICE Project, an observational, prospective cohort study of 9256 women in St. Louis, MO, USA. Our sample included 6744 women who initiated a contraceptive method within 3 months of enrollment, continued use at 6 months post-enrollment, and responded regarding dual method use. Our primary outcome was the rate of dual method use at 6 months post-enrollment.

resultsDual method use was reported by 32% of LARC and 45% of non-LARC hormonal contraceptive users (p < .01). After adjusting for other covariates and comparing to non-LARC hormonal contraceptive users, LARC users were less likely to report dual method use (RR

conclusionsLARC users are less likely to report dual method use compared to non-LARC hormonal contraceptive users, but other factors also impact dual method use. Further studies should be performed to determine whether this lower dual method use increases the risk of STI. CLINICAL TRIALS REGISTRATION: Clinicaltrials.gov Identifier NCT01986439.
