Cold storage effects on immature calliphoridae: Survival limits and forensic consequences for PMI estimation.
Article in Journal of forensic sciences, 2026. 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
This study investigated the effects of continuous refrigeration (4°C ± 2°C and 50% ± 5% RH) on the development and survival of immature stages (eggs, first, second, and third instar larvae, and pupae) of four forensically important blowfly species (Chrysomya megacephala, Chrysomya putoria, Hemilucilia segmentaria, and Lucilia cuprina) compared to a control group (27°C ± 2°C and 50% ± 5% RH). Groups of approximately 500 individuals at each stage were exposed to refrigeration and the control treatment, with periodic verifications to assess development and survival. Statistical analysis (two-way ANOVA and Šidák posthoc test) revealed significant differences (p < .0001) in development time and survival between the groups. Eggs and first instar larvae did not survive longer than 36 h under refrigeration. Third instar larvae showed greater resistance, with L. cuprina surviving for up to 612 h, entering quiescence without molting. The results highlight the significant impact of refrigeration on the development of these warm-climate species, warning against potential imprecisions in time of colonization (TOC) estimations and, consequently, in postmortem interval (PMI) if refrigeration effects are not considered. The research emphasizes the need for species-specific data and caution when applying linear development models in forensic entomology, especially in cases involving refrigeration.
