Association between prognostic nutritional index and prognosis of patients receiving coronary artery bypass grafting surgery: a systematic review and meta-analysis.
Review in Frontiers in cardiovascular medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Objectives: To conduct the first systematic review and meta-analysis to assess the association between prognostic nutritional index (PNI) and prognosis of patients receiving coronary artery bypass grafting surgery (CABG). Methods: We conducted a systematic literature search via PubMed, Embase, Web of Science, and Cochrane until March 2025, for studies that evaluated the association between PNI and prognosis of patients receiving CABG. All-cause mortality and acute kidney injury (AKI) were the primary outcomes. Odds ratios (OR) and 95% confidence intervals (CI) were used for data pooling. In addition, sensitivity analysis and subgroup analysis were performed to evaluate the stability of the results and potential sources of heterogeneity. All data analyses were conducted using Review Manager 5.4 and STATA 15.1 software. Results: A total of 11 studies including 11,444 patients were included in the meta-analysis. The results showed that, compared with the low PNI group, the high PNI group had a significantly lower all-cause mortality rate (OR: 0.81; 95% CI: 0.72, 0.90) and a significantly lower risk of acute kidney injury (OR: 0.82; 95% CI: 0.77, 0.86). Sensitivity analyses confirmed that the associations between PNI and all-cause mortality and AKI were stable. Conclusions: PNI can effectively predict postoperative all-cause mortality and AKI in patients undergoing CABG. Considering the inevitable heterogeneity and potential publication bias in this article, more large-scale, multicenter, prospective cohort studies are needed in the future to assess the predictive value of PNI for prognosis after CABG and to identify its influencing factors.
