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.

2 · The registry

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

backgroundUse of a reliable contraception method has become an inclusion criterion in prevention trials to minimize time off product. We report on hormonal contraceptive prevalence, uptake, sustained use and correlates of use in the Microbicides Development Programme (MDP 301) trial at the Masaka Centre in Uganda.

methodsHIV negative women in sero-discordant relationships were enrolled and followed-up for 52 to 104 weeks from 2005 to 2009. Contraceptive use data was collected through self-report at baseline and dispensing records during follow-up. Hormonal contraceptives were promoted and provided to women that were not using a reliable method at enrolment. Baseline contraceptive prevalence, uptake and sustained use were calculated. Uptake was defined as a participant who reported not using a reliable method at enrolment and started using a hormonal method at any time after. Logistic regression models were fitted to investigate predictors of hormonal contraceptive uptake.

resultsA total of 840 women were enrolled of whom 21 aged ≥50 years and 12 without follow-up data were excluded; leaving 807 (median age 31 IQR 26-38) in this analysis. At baseline, 228 (28%) reported using a reliable contraceptive; 197 hormonal, 28 female-sterilisation, two IUCD and one hysterectomy. As such 579 were not using a reliable contraceptive at enrolment, of whom 296 (51%) subsequently started using a hormonal contraceptive method; 253 DMPA, four oral pills, and two norplant. Overall 193 (98%) existing users and 262 (88%) new users sustained use throughout follow-up. Independent correlates of hormonal contraceptive uptake were: younger women ≤30 years, aOR = 2.5, 95% CI: 1.7-3.6 and reporting not using contraceptives at baseline due to lack of access or money, breastfeeding or other reasons, in comparison to women who reported using unreliable method.

conclusionPromotion and provision of hormonal contraception doubled the proportion of women using a reliable method of contraception. Uptake was pronounced among younger women and those not previously using a reliable method because of lack of access or money, and breastfeeding. Promotion and provision of hormonal contraceptives in trials that require the interruption or discontinuation of investigational products during pregnancy is important to reduce the time off product.
