Discordance between self-reported contraceptive use and detection of exogenous hormones among Malawian women enrolling in a randomized clinical trial.
Trial report in Contraception, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
objectiveThe objective was to assess the extent of concordance between self-reported contraceptive use and the presence of contraceptive progestins in serum. STUDY
designWe evaluated self-reported contraceptive use by using radioimmunoassay to examine baseline serum levels of medroxyprogesterone acetate (MPA) and levonorgestrel (LNG) among 97 Malawian women enrolling in a contraceptive trial.
resultsTwelve percent (12/97) of study participants who reported no hormonal contraceptive use in the previous 6months had either MPA or LNG detected in their serum.
conclusionsThe observed discordance between self-report and detection of exogenous hormones in serum indicates that caution is warranted when drawing conclusions based on self-reported contraceptive use.
