In one paragraph

Trial report in Contraception, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.

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

backgroundThe study was conducted to assess socio-behavioral and biological factors associated with unplanned pregnancy in the US cohort of a microbicide trial. STUDY

designWe conducted a mixed-method, nested case-control study of risk factors for pregnancy within the US cohort of the microbicide trial HPTN 035. We developed an instrument to assess attitudes and beliefs about fertility control/contraceptive utilization among 122 women. Cases were HPTN 035 participants who became pregnant while enrolled, matched by time on study 1:4 with controls. Univariable and multivariable analysis were performed with pregnancy as the outcome of interest.

resultsContraceptive method change during the trial was associated with unplanned pregnancy (OR=1.76). Participant desire/partners' desire for future children (OR=4.95) and young age (OR=0.88 annually above age 19 years) were independently associated with unintended pregnancy.

conclusionWithin a trial that enroll heterosexually active women, there may be ways to identify those at highest risk of becoming pregnant a priori.
