Chloroquine and its derivatives in the management of COVID-19: A scoping review
Article in Biomedica : revista del Instituto Nacional de Salud, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Introduction: Recently, researchers from China and France reported on the effectiveness of chloroquine and hydroxychloroquine for the inhibition of SARS-CoV-2 viral replication in vitro. Timely dissemination of scientific information is key in times of pandemic. A systematic review of the effect and safety of these drugs on COVID-19 is urgently needed. Objective: To map published studies until March 25, 2020, on the use of chloroquine and its derivates in patients with COVID-19. Materials and methods: We searched on PubMed, Embase, Lilacs, and 15 registries from the World Health Organization’s International Clinical Trials Registry Platform for theoretical and empirical research in English, Spanish, Italian, French, or Portuguese until March 25, 2020, and made a narrative synthesis of the results. Results: We included 19 records and 24 trial registries (n=43) including 18,059 patients. China registered 66% (16/24) of the trials. Nine trials evaluate chloroquine exclusively and eight hydroxychloroquine. The records are comments (n=9), in vitro studies (n=3), narrative reviews (n=2), clinical guidelines (n=2), as well as a systematic review, an expert consensus, and a clinical trial. Conclusions: One small (n=26), non-randomized, and flawed clinical trial supports hydroxychloroquine use in patients with COVID-19. There is an urgent need for more clinical trial results to determine the effect and safety of chloroquine and hydroxychloroquine on COVID-19.
