The prognostic value of the prognostic nutritional index for short- and long-term outcomes in coronary care unit patients.
Article in BMC cardiovascular disorders, 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
backgroundSystemic inflammation is associated with the outcomes of coronary care unit (CCU) patients. We sought to assess the prognostic implication of the prognostic nutritional index (PNI), a surrogate marker of inflammation in CCU patients.
methodsThe study included 1,158 participants from the Medical Information Mart for Intensive Care-IV (MIMIC-IV) database and 342 from the Second Affiliated Hospital of Wenzhou Medical University (WMU), participants were subsequently grouped based on the PNI threshold. Key endpoints were 30-day mortality and major adverse cardiovascular events (MACEs) at 1-year follow-up and were examined with propensity score matching (PSM) and Cox regression analysis. The prognostic implications of PNI and other inflammatory markers were compared using an area under the curve (AUC).
resultsA total of 285 participants in the MIMIC-IV cohort developed 30-day mortality, and 139 developed MACEs in WMU, of which 103 (30.12%) died, 19 (5.56%) experienced non-fatal myocardial infarction, and 29 (8.48%) experienced non-fatal stroke. PNI was significantly associated with short-term mortality (HR
conclusionPNI emerges as a potential prognostic marker for anticipating adverse outcomes in CCU patients, the intrinsic cause may attribute to malnourished status and inflammation.
