Reflections on Participation in a Trial on Hydroxychloroquine as Prevention for COVID-19 among Health Workers in Niger.

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
In 2020, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a rapidly emerging virus causing the coronavirus disease 2019 (COVID-19) pandemic, had no known effective prophylaxis and no widely available proven effective antiviral treatment. Hydroxychloroquine/Chloroquine was identified as an early potential therapeutic candidate drawing on evidence from reports of both in vitro and in vivo testing. A multicountry placebo-controlled randomized trial was set to evaluate the use of hydroxychloroquine/chloroquine to prevent infection in healthcare workers and staff working in a health facility involved in COVID-19 management. One of the sites of this trial was in Niger. In Niger, of the 240 persons who were provided information about the study and with whom participation was discussed, only five participants provided their informed consent. In this article, we describe the key difficulties encountered in the conduct of this trial from the perspective of the site study team. Among the difficulties, we recognize that the epidemic context, controversy surrounding hydroxychloroquine, vaccine rollout, participants' perspectives, and trial design had a major impact on participation.
