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

Background: Despite advancements in reperfusion strategies, patients with acute myocardial infarction (AMI) face significant risks of long-term mortality. Systemic inflammation and nutritional/immune depletion synergistically impact prognosis. This study investigated the prognostic value of the neutrophil count to prognostic nutritional index ratio (NPNR)-a novel composite index reflecting inflammatory burden and nutritional reserves-in AMI patients. Methods: This dual-cohort study included 2020 patients from the NOAFCAMI-SH registry in China and 1,433 patients from the MIMIC-IV database in the USA. The primary endpoint was all-cause mortality; the secondary endpoint was cardiovascular mortality. Associations were analyzed using Kaplan-Meier curves, Cox regression, and restricted cubic splines. Results: During a median 2.5-year follow-up in the discovery cohort, 285 all-cause and 234 cardiovascular deaths occurred. Higher NPNR levels correlated with myocardial injury and lower LVEF. Kaplan-Meier analysis showed significantly worse survival with elevated NPNR ( Conclusion: NPNR is a robust, independent predictor of long-term all-cause and cardiac mortality in AMI patients, validated in the external MIMIC-IV cohort. This simple biomarker effectively aids in risk stratification.
