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: Intentional and accidental organophosphorus exposures pose a significant healthcare-related burden on South African communities. This study will review the demographics, characteristics and clinical course of patients presenting with features of acute organophosphorus toxicity to a regional Emergency Centre in Johannesburg, South Africa. Methods: This was a retrospective chart review of all patients treated for possible acute organophosphorus toxicity from January 2020 to August 2021. Results: A total of 205 patients were identified of which 134 patients were included in the study. The median age was 26 years with a male predominance (male= 56%, female=44%). 109 patients (81.3%) survived, 18 patients (13.4%) demised and the outcome of 7 patients (5.2%) was unknown. The median hospital length of stay was 8 days, (IQR= 5-13 days), and the longest hospital stay was 37 days in ICU. Atropinisation dose was significantly higher for intubated patients (median=140.0mg; IQR=90mg-219.5mg) compared to patients who were not intubated (median=60mg; IQR=20.5mg-120mg, Conclusion: Our study shows a high mortality rate secondary to organophosphorus toxicity. Significant exposures and thus higher doses of atropine were associated with increased length of stay and need for intubation. We found a high incidence of atropine-related adverse effects. More studies are needed to further establish the balance between the therapeutic and adverse effects of high-dose atropine as a treatment modality for organophosphorus toxicity.
