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

Background: Malaria elimination in mobile and hard-to-reach populations calls for novel, tailored interventions. In French Guiana, the malaria burden is high among the population working in illegal gold mining. Between April 2018 and March 2020, we implemented Methods: We fitted mathematical models of the transmission of Findings: Treatment coverage increased in the intervention compared to the pre-intervention period, the effect being stronger for Interpretation: Malakit had a significant impact on malaria transmission by improving the access to treatment for the population working in illegal gold mining in French Guiana. Building on the regional efforts of the past fifteen years, Malakit contributed to another step towards malaria elimination in the Guiana Shield. Funding: European Union, Global Fund, MoH of Brazil, Cayenne Hospital, Health Regional Agency of French Guiana.
