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: Determining the postmortem interval (PMI) in forensic cases involving children is challenging owing to limited evidence. Deciduous teeth are valuable in forensic analysis because of their ability to preserve deoxyribonucleic acid (DNA) for longer than other tissues. Aim: This study investigated the effect of storage conditions (wet vs dry) on DNA degradation and microbial dynamics in deciduous teeth. Materials and methods: Forty-eight deciduous teeth from children aged 5-10 years were stored under wet or dry conditions. Each condition was evaluated at three time points: baseline (immediately postextraction), 1 month, and 6 months. DNA was extracted and quantified, and microbial profiles were analyzed using polymerase chain reaction (PCR) to detect common oral bacteria. Results: DNA quantification was highest immediately after extraction, with a significant decline over time. Under dry conditions, DNA levels remained higher than those under wet conditions. For dry storage, DNA quantification showed significant differences ( Conclusion: The environment in which deciduous teeth are stored significantly affects DNA preservation and microbial dynamics. These findings highlight the impact of environmental factors on DNA integrity and microbial profiles, emphasizing their importance in forensic analysis. Clinical significance: This study underscores the role of the environmental context in which teeth are found, affecting DNA and microbial data. This is crucial for accurate PMI estimation and forensic investigation of pediatric patients. How to cite this article: Reddy H, Saha S, Nair MR,
