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

purposeTo collect information on unintended drug exposure during pregnancy in early clinical drug development. MATERIALS AND

methodsQuestionnaire mailed in autumn 2015 to members of human pharmacology societies in Europe for anonymous responses via the online tool SurveyMonkey.

results53 of the ~ 700 addressees participated in the survey. 23 female trial participants and 11 female partners of male trial participants were exposed to investigational medicinal products during unintended pregnancies in a clinical trial. Most survey respondents confirmed adequate contraceptive methods by in/exclusion criteria and the use of pregnancy tests in female trial participants at screening and before the first dose. The last menstrual period was documented less frequently (at screening: 28 of 44, before first dose: 5 of 44 respondents). A considerable proportion of respondents denied the routine use of compliance checks about the appropriate use of contraceptive methods, had no procedures in place if contraceptive methods failed, and did not train physicians in instructing trial participants about the appropriate use of contraceptive methods.

conclusionThe methods to avoid unintended pregnancies during participation in a clinical trial need improvement and should include (i) pregnancy tests, (ii) documentation of last menstrual period before the first dose, (iii) compliance checks of the appropriate use of contraceptive methods, and (iv) training of trial physicians. Procedures should be in place for what to do if contraceptive methods fail.
