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

introductionOptimization of modifiable risk factors prior to elective ventral hernia repair (VHR) improves outcomes. There is no well-established correlation between nutritional status and outcomes after VHR. Prognostic nutritional index (PNI) is a measure of immune and nutritional status, incorporating albumin and total lymphocyte count. We aim to evaluate the association between PNI and clinical outcomes after open VHR.

methodsWe retrospectively reviewed adult patients who underwent open elective VHR (> 3 cm) between 2023 and 2025 with recent (< 1 month preop) albumin and lymphocyte count, categorized as low PNI (< 45) or normal PNI (≥ 45). Statistical analyses included standard univariate and multivariate logistic regression.

results125 patients were included; 42 (33.6%) with low and 83 (66.4%) with normal PNI. 62.4% were male, 75.2% ASA III-IV, 32.8% diabetic, with 32% recurrent hernia on presentation and average defect size of 85.53 ± 98.82cm

conclusionPNI is an independent predictor of surgical site infection after open VHR, and results in longer LOS and higher utilization of rehabilitation services post-discharge. This data may help inform preoperative discussions and risk-stratification. Further studies are warranted to determine whether immunomodulating supplements before elective VHR may improve these measures in patients with low PNI.
