Postmortem Sperm Retrieval in Hanging-Induced Mechanical Asphyxia: Probability and Temporal Dynamics.
Article in Journal of human reproductive sciences. 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
Aim: To assess the feasibility of retrieving viable spermatozoa in hanging deaths and their correlation with post-mortem interval (PMI) and sperm quality parameters. Settings and Design: A descriptive observational study was conducted at the Department of Forensic Medicine and Toxicology, AIIMS Bhopal. Materials and Methods: PMSR was performed in 18 medicolegal autopsy cases involving males aged 18-49 years within 24 h of death using an in-house innovated vaso-epididymal wash technique. Sperm motility and viability were assessed using an automated semen quality analyser and the eosin dye exclusion test. Statistical Analysis Used: Data were analysed using descriptive statistics, Pearson's correlation and Chi-square tests. Results: Motile sperm were recovered in 44.4% and viable sperm in 50% of cases. Mean motility and viability in positive samples were 14.5% and 29.9%, respectively. Viability stays up to 21.5 h post-mortem, peaking at 72%. No significant correlation was seen between PMI and sperm quality. A strong association between immotile and viable sperm supports a two-step degradation process, with motility loss preceding cellular death. Conclusion: Our results confirm the recovery of motile and viable sperm in 50% of hanging-related deaths up to 21.5 h post-mortem (peak 72%,
