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
purposeSurgical site infection (SSI) is a serious complication of spinal instrumentation surgery. Various risk factors, including nutrition, immunity, and inflammation, have been reported. Recently, similar variables have been reported to help predict cancer prognosis. This study aimed to determine whether cancer prognostic factors are useful in predicting the occurrence of SSI in spinal instrumentation surgery, given the overlap between the factors associated with cancer progression and SSI occurrence.
methodsWe retrospectively analyzed 451 out of 828 patients who underwent spinal instrumentation surgery between 2013 and 2021. The patients were divided into an SSI group (Group I) and a non-SSI group (Group N). Blood samples collected within 3 months before surgery were used to examine the prognostic nutritional index (PNI), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), lymphocyte-C reactive protein (CRP) ratio (LCR), and modified Glasgow prognostic score (mGPS). Univariate and multivariate logistic regression analyses were used to identify independent predictors.
resultsSSI occurred in 12 patients (2.6%). Univariate analysis showed significant differences in PNI, NLR, LCR, and mGPS between groups. Multivariate analysis showed that only mGPS (odds ratio [OR] = 2.72, 95% confidence interval [CI] 1.45-5.11, p = 0.0019) was an independent predicting factor. Receiver operating characteristic curve analysis showed a cutoff value of 1 for the mGPS (AUC = 0.723).
conclusionsmGPS was a significant independent predictive factor for SSI after spinal instrumentation surgery. Since mGPS is based on serum albumin and CRP levels, optimizing preoperative nutritional status and management of CRP levels are crucial for preventing SSI.
