1 · What the graph read from it

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.

2 · The registry

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

backgroundDetermining the cause of death in suspected asphyxia is often difficult when external findings are absent. Mast cells (MCs) may provide objective histological evidence of hypoxia.

objectiveTo compare the efficacy of immunohistochemistry (IHC) using CD117 with Toluidine Blue (TB) and Giemsa (GM) stains in detecting mast cells in asphyxial and non-asphyxial lung tissues. MATERIALS AND

methodsLung samples from 164 medicolegal autopsies at AIIMS Jodhpur were studied, 57 asphyxial and 107 non-asphyxial deaths. Peribronchial and perialveolar regions were examined using TB, GM, and IHC (CD117). Mean mast cell counts were compared using Mann-Whitney U and Kruskal-Wallis tests.

resultsMast cell counts were significantly higher in asphyxial cases. Peribronchial counts: IHC 2.27 ± 1.02, TB 2.29 ± 1.19, GM 0.84 ± 0.59. Perialveolar counts: IHC 0.74 ± 0.12, TB 0.10 ± 0.19, GM 0.01 ± 0.51. IHC was more sensitive than GM (P < 0.001), while TB showed comparable efficacy to IHC.

conclusionCD117-based IHC is the most sensitive method for identifying mast cells in asphyxial lungs, though TB remains a valuable low-cost option. Mast cell analysis can serve as an adjunct marker in diagnosing mechanical asphyxia.
