Postmortem Lividity Color Change During Rewarming Following Cold Storage: A Case Report of Drowning.
Article in Cureus, 2025. 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
Postmortem lividity typically presents as purplish discoloration due to the accumulation of deoxygenated blood in dependent body regions after death. However, certain pathological and environmental conditions can alter its appearance, occasionally resulting in a cherry-red hue that may mislead forensic interpretation. We report a case of drowning in which postmortem lividity appeared cherry-red following cold storage but gradually turned purplish during surface rewarming before autopsy. This observation illustrates the reversible, temperature-dependent behavior of lividity dominated by oxygenated hemoglobin (O₂Hb), contrasting with the stable coloration seen in carbon monoxide (CO) poisoning. Understanding such changes is critical in forensic evaluations to avoid diagnostic pitfalls associated with livor mortis coloration.
