A novel approach, exploring subgingival temperature changes over time since death: An animal study.
Article in Journal of Indian Society of Periodontology. 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: Accurate estimation of the postmortem interval (PMI) is a crucial aspect of forensic investigations. Traditional methods rely on rectal temperature measurement, but alternative sites may provide more reliable measurements under certain conditions. The subgingival region, being a well-insulated anatomical site, has been considered for temperature-based assessments. However, no studies have explored its viability in PMI estimation. This study aims to assess subgingival temperature changes before and after euthanasia in rats and rabbits and compare them with rectal temperature variations. Understanding these temperature shifts could help clarify the forensic relevance of subgingival temperature as an alternative or complementary method for PMI estimation. Objective: To evaluate pre-euthanasia and posteuthanasia changes in subgingival and rectal temperatures in rats and rabbits. Materials and Methods: Based on a pilot study, the sample size was calculated ( Results: Subgingival temperature before euthanasia was the only statistically significant finding ( Conclusion: Both subgingival and rectal temperatures decreased after euthanasia, confirming a postmortem temperature decline. However, the results were not statistically significant due to the small sample size. With further research overcoming these limitations, subgingival temperature could serve as a potential alternative for PMI estimation.
