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
backgroundOrganophosphorus poisoning is a major health hazard in developing countries. We conducted a study to compare the Acute Physiology, Age and Chronic Health Evaluation II (APACHE II) scoring system and Peradeniya Organophosphorus Poisoning Scale in predicting the complications, ventilator requirement and mortality in patients of Acute Organophosphorus Poisoning. METHODOLOGY: A prospective observational study was done on 100 patients above 18 years of age, presenting with alleged history of consumption of organophosphorus compounds. The patients were evaluated for the required details to calculate the APACHE II score and Peradeniya Organophosphorus Poisoning Scale and were followed up till discharge or mortality to identify the complications, ventilator requirement and mortality. This data was tabulated using Excel and analyzed using SPSS software to look for correlation between the scores and the outcome.
resultsThe mean age of our patients was 33.64 ± 12.99 years. The APACHE II cutoff score for complications, ventilator requirement and mortality was ≥ 7 (sensitivity 94.3%, specificity 96.9%, Area under Receiver Operator Characteristic (ROC) 0.99, p < 0.01), ≥9 (sensitivity 86.7%, specificity 82.4%, Area under ROC 0.91, p < 0.01) and ≥16 (sensitivity 85.7, specificity 96.8%, Area under ROC 0.98, p < 0.01) respectively. Similarly, the Peradeniya Organophosphorus Poisoning Scale cutoff was for complications, ventilator requirement and mortality was ≥ 3 (sensitivity 80%, specificity 92.3%, Area under ROC 0.90, p < 0.01), ≥3 (sensitivity 80%, specificity 75.3%, Area under ROC 0.85, p < 0.01) and ≥7 (sensitivity 85.7%, specificity 97.8%, Area under ROC 0.99, p < 0.01) respectively.
conclusionBoth APACHE II and POPS demonstrated good predictive performance for adverse outcomes in acute organophosphorus poisoning. Both scores showed excellent discrimination for mortality, with no statistically significant difference between their AUCs.
