Toxicological profile and prognostic factors in phosphide poisoning: insights from a one-year hospital-based study.

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
introductionThe primary objective of this study was to compare the mortality rates and clinical severity of aluminum phosphide (AlP) versus zinc phosphide (ZnP) poisoning. The secondary objectives were to identify specific prognostic factors such as method of ingestion and clinical markers (hypotension, acidosis) and to describe the epidemiological profile of these cases in Khorramabad, Iran.
methodsA retrospective, cross-sectional study was conducted by reviewing the medical records of 59 patients admitted for AlP or ZnP poisoning to Shahid Rahimi Hospital in Khorramabad during 2021–2022. Data on demographic characteristics, poisoning details, clinical course, and outcomes were collected. Statistical analysis was performed using SPSS version 20, employing descriptive statistics, Chi-square, Fisher’s exact, and independent t-tests.
resultsThe majority of patients were male (52.5%), with a mean age of 30.12 ± 11.96 years. AlP poisoning accounted for 69.5% of cases, with a significantly higher mortality rate (29.3%) compared to ZnP, which had a single fatality. The method of ingestion was a critical prognostic factor for AlP; patients who consumed it without dissolving it in water had a markedly higher mortality rate (50%) than those who dissolved it first (6.7%). The development of hypotension (P < 0.001) and metabolic acidosis (P = 0.003) within the first 48 h were strongly associated with mortality in AlP poisoning. AlP poisoning accounted for 69.5% of cases, with a significantly higher mortality rate (29.3%) compared to ZnP, which had no fatalities (0%). The method of ingestion was a critical prognostic factor for AlP. Intensive care unit (ICU) admission was also a significant predictor of poor outcome. In contrast, no significant association was found between prognosis and gender, psychiatric history, physical form of the poison, or time to hospital presentation. Aluminum phosphide is significantly more lethal than zinc phosphide, largely due to its form, leading to internal phosphine gas release. The consumption method, along with the development of hypotension and metabolic acidosis, are crucial prognostic indicator for AlP poisoning.
conclusionThese findings underscore the need for aggressive management of metabolic acidosis and hypotension. Stricter enforcement of pesticide sales bans, enhanced safety protocols to prevent accidental exposures, and further research on ZnP poisoning are strongly recommended.
