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

Background: The Prognostic Nutritional Index (PNI) is a numerical score used to assess the nutritional and immunological status, derived from serum albumin concentration and lymphocyte count. While malnutrition and systemic inflammation are known to influence surgical outcomes and cancer prognosis, the predictive value of PNI in colorectal cancer (CRC) is underexplored. This study aimed to evaluate whether preoperative PNI predicts postoperative complications and long-term survival in patients with CRC undergoing curative-intent surgery. Methods: The records of 2,026 patients who underwent curative-intent surgery for CRC between 2011 and 2023 at a tertiary center in Taiwan were retrospectively reviewed. Propensity score matching (PSM) was used and patients were stratified into high and low PNI groups based on the median value. Outcomes included in-hospital complications, 5-year overall survival (OS), and disease-free survival (DFS) in the subgroup of patients with stage I-III disease. Multivariable logistic regression and Cox proportional hazards models were used as well as restricted cubic spline (RCS) analysis. Results: High PNI was independently associated with lower rates of overall complications (adjusted odds ratio [aOR] = 0.22, 95% confidence interval [CI]: 0.17-0.28), ileus (aOR = 0.23), anastomotic leakage (aOR = 0.16), and lung-related complications (aOR = 0.38). High PNI was also significantly associated with improved 5-year OS (aHR = 0.45, 95% CI: 0.38-0.55), but not DFS. In additional competing-risk and comorbidity-stratified analyses, high PNI remained protective for both cancer-related (p = 0.0005) and non-cancer-related mortality (p < 0.0001), with consistent effects across CCI strata and attenuation for cancer-related death in CCI ≥ 3 (p = 0.1024). Additionally, PNI demonstrated superior predictive performance over the neutrophil-to-lymphocyte ratio (NLR) for all complication types based on receiver operating characteristic (ROC) analysis. Conclusion: Preoperative PNI was independently associated with postoperative complications and OS in patients with CRC undergoing curative surgery. Routine assessment of PNI may help refine risk stratification and guide perioperative management to improve surgical outcomes.
