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

introductionBenznidazole is the preferred drug for treatment of Chagas disease. However, it is toxic and of limited value in chronic infection.

objectiveWe aimed to estimate the rates of and factors related to adverse reactions (ARs) to benznidazole and treatment discontinuations (TDs).

methodsA meta-analysis was performed using an electronic search of the published literature with no language restrictions until June 2017. Prospective studies were included of chronically infected patients in which at least one treatment arm included benznidazole. Data were added from a prospective cohort of patients with Chagas disease at our centre (January 2007-June 2017). Weighted rates of ARs and TDs were estimated, and potentially related factors were analysed.

resultsSome 413 studies were found, from which we chose 42 (nine clinical trials and 33 observational studies, including ours), comprising data for 7822 patients. The weighted rate of ARs to benznidazole was 44.1% (95% confidence interval [CI] 37.2-51.2). ARs were more frequent in adults than in children (51.6 vs. 24.5%), with the most common being skin reactions (34%), gastrointestinal complaints (12.6%) and neurological symptoms (11.5%). Grade 4 ARs were recorded in 3% of cases. The weighted rate of TDs was 11.4% (95% CI 8.5-14.5); TDs were more frequent in adults than in children (14.2 vs. 3.8%). In our cohort, only female sex was related to an increased rate of ARs but not to TDs.

conclusionBenznidazole had a poor tolerability profile, with a high incidence of TDs, especially in adult patients and women. Optimised dosing schedules and/or new drugs are urgently needed.
