Preoperative Naples Prognostic Score and outcomes after isolated coronary artery bypass grafting: a retrospective cohort study.
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
backgroundInflammatory and nutritional status may refine risk assessment before coronary artery bypass grafting (CABG). This study evaluated the association between preoperative Naples Prognostic Score (NPS) and early and follow-up outcomes after isolated CABG.
methodsThis single-center retrospective cohort included adults who underwent isolated CABG between 2020 and 2023. Patients without a recorded preoperative NPS were excluded. The recorded NPS (0-4) was categorized as low (score 0), intermediate (scores 1-2), or high (scores 3-4). Outcomes were institutionally recorded binary event indicators. Logistic regression evaluated associations with 30-day major adverse cardiac and cerebrovascular events (MACCE), follow-up MACCE, and follow-up all-cause death.
resultsThe analytic cohort included 332 patients: 16 low-NPS, 193 intermediate-NPS, and 123 high-NPS patients. Follow-up all-cause death occurred in 25 patients (7.5%) and was more frequent in the high-, intermediate-, and low-NPS groups, respectively (15.4%, 3.1%, and 0.0%; exact P < 0.001). Any follow-up MACCE occurred in 45 patients (13.6%; 18.7%, 11.4%, and 0.0% across the same groups; exact P = 0.050). Thirty-day MACCE occurred in 11 patients (3.3%); its analyses were exploratory. Per 1-point increase in NPS, the adjusted odds ratio for follow-up all-cause death was 1.69 (95% CI 1.00-2.84; P = 0.048) in the clinical model and 2.06 (95% CI 1.25-3.39; P = 0.005) in the EuroSCORE II complete-case model.
conclusionsHigher preoperative NPS was associated with greater follow-up all-cause mortality after isolated CABG. Associations with composite MACCE were less consistent after adjustment. NPS may support inflammatory-nutritional risk interpretation alongside established surgical risk assessment, but the findings require confirmation in cohorts with standardized follow-up and time-to-event data.
