Variance in intraindividual stability of vitreous humor for thanatochemistry.
Article in International journal of legal medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
introductionThis study investigates the intraindividual variability and ex-vivo stability of vitreous humor (VH) analytes for forensic thanatochemistry. VH, an anatomically isolated and robust postmortem fluid, provides valuable insights into the postmortem interval (PMI) and potential antemortem medical conditions. MATERIALS AND
methodsA total of 207 VH samples were collected from 36 cases and divided into three cohorts: serial sampling across three days postmortem, intraindividual variability assessment using triplicates, and ex-vivo stability evaluation through freeze-thaw cycles.
resultsLinear relationships between PMI and potassium, calcium, creatinine, and lactate were identified, but their non-linear trends limited PMI estimation accuracy. Sodium, chloride, and glucose demonstrated variations linked to cardiovascular and infectious conditions, while elevated urea and creatinine correlated with renal or multi-organ failure. The study highlighted the importance of interpreting these biochemical markers in conjunction with clinical and environmental factors to improve reliability. DISCUSSION: Ex-vivo stability testing revealed relevant variations in VH levels, emphasizing the need for standardized pre-analytical handling. Overall, while VH analytes offer promising forensic applications, their use for PMI estimation and medical diagnoses requires cautious interpretation within a multidisciplinary context.
