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

purposeIn Democratic Republic of the Congo (DRC), informal coltan mining has been expanding amidst increased insecurity due to armed conflicts. We investigated the impact of occupational dust-exposure on the respiratory health of Congolese coltan miners.

methodsIn total, 441 Congolese workers participated in this study, including 199 informal coltan miners and 242 office workers (controls). Information on respiratory complaints was collected using two standardized questionnaires. Physical examination (vital signs, auscultation) and lung function test (Peak Flow meter) were performed. In addition, workplace airborne PM2.5 and volatile organic compounds (VOC) concentrations were measured.

resultsHigher airborne PM2.5 (range 180-210 µg/m

conclusionsThis study showed high prevalence of respiratory complaints in Congolese informal coltan miners, suggesting the necessity to implement efficient occupational safety measures and regulate this informal mining business.
