Impact of prognostic nutritional index on postoperative outcome of acute empyema.
Article in Journal of thoracic disease, 2025. 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
Background: The prognostic nutritional index (PNI) is a useful prognostic index for postoperative outcomes in many fields. We investigated the usefulness of the PNI as a prognostic biomarker of 1-year postoperative survival for acute empyema. Methods: The subjects of this retrospective study were patients who underwent surgery for acute empyema at NHO Iwakuni Clinical Center between November 2009 and March 2022, and they were divided into two groups: those who survived after surgery (survival group) and those who died from all-cause within 1 year after surgery (death within 1-year group). The preoperative PNI calculated within 3 days before surgery and the postoperative PNI calculated 7 days after surgery were compared between the two groups. An appropriate cutoff value of the preoperative PNI was set for the 1-year survival analyses after surgery. Results: A total of 75 patients were included. The preoperative PNI was significantly lower in the death within 1-year group (n=13) than in the survival group (n=62) (P=0.01) and was significantly associated with prolonged postoperative hospital stay (r=-0.51, P<0.001). Patients with preoperative PNI >29.3 had significantly better 1-year survival than those with an index ≤29.3 (P=0.02). In patients with a preoperative PNI ≤29.3, patients who had a higher postoperative index than the preoperative index had as good 1-year survival as those with preoperative PNI >29.3 (P=0.19). Conclusions: The PNI may be a predictor of postoperative prognosis and an indicator of postoperative treatment efficacy in acute empyema.
