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

Acute ischemic heart disease (AIHD) is a major cause of sudden cardiac death, yet postmortem diagnosis is difficult, particularly in early-phase ischemic injury or decomposed bodies. We investigated the diagnostic value of two molecular biomarkers—8-hydroxy-2′-deoxyguanosine (8-OHdG), indicating oxidative DNA damage, and N-terminal pro-brain natriuretic peptide (NT-proBNP), reflecting cardiac wall stress—in 67 human forensic autopsy cases (33 AIHD, 34 non-AIHD). Immunohistochemistry revealed significantly greater and more diffuse nuclear 8-OHdG expression in AIHD cardiomyocytes compared with controls. Postmortem blood NT-proBNP levels were also significantly higher in AIHD cases (2389.1 ± 499.6 pg/mL) than in non-AIHD cases (896.1 ± 190.1 pg/mL). No significant correlations were found between 8-OHdG expression and NT-proBNP levels, contraction band necrosis, postmortem interval, age, or sex, suggesting that these markers reflect distinct pathological processes—oxidative injury and hemodynamic stress. Both markers demonstrated postmortem stability, and their combined evaluation improved diagnostic confidence in cases with inconclusive histology. This dual-biomarker approach may enhance the accuracy of AIHD diagnosis in forensic practice and provide complementary insights into the molecular mechanisms underlying sudden cardiac death.
