Methanol-related deaths: evaluation of findings in a 111-case autopsy series.
Article in Frontiers in neurology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Methanol poisoning is a significant public health problem associated with high mortality and severe neurological damage. This study aimed to evaluate the relationship between central nervous system (CNS) findings, blood methanol levels, and hospitalization duration in fatal methanol poisoning cases. Materials and methods: A total of 111 cases with confirmed death due to methanol poisoning, autopsied between January 1, 2021 and June 30, 2025, were retrospectively analyzed. Scene investigation, clinical, toxicological, and histopathological findings were evaluated. CNS findings were analyzed in relation to methanol concentrations and duration of hospitalization. Statistical analyses were performed using IBM SPSS Statistics version 27. Results: The majority of cases occurred during the COVID-19 period (66.7%), with a marked male predominance (92.8%). Exposure most frequently occurred in domestic settings (58.6%). The mean blood methanol level was 230.2 mg/dl (range: 12-827), and levels > 100 mg/dl were detected in 59.5% of cases. Higher blood methanol levels were significantly associated with shorter hospitalization duration ( Conclusion: Neuropathological findings were more frequently observed in cases with longer hospitalization durations. In high-dose methanol intoxication, rapid death may prevent the development of detectable structural CNS lesions; therefore, the absence of CNS pathology does not exclude fatal methanol intoxication. Furthermore, postmortem methanol levels may be reduced by medical treatment, emphasizing the need for a comprehensive forensic evaluation integrating toxicological, clinical, and treatment data.
