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
objectiveTo investigate whether the Geriatric Nutrition Risk Index (GNRI) can serve as an independent predictor of postoperative urinary retention (PUR) in elderly patients undergoing transforaminal lumbar interbody fusion (TLIF).
methodsThis retrospective study reviewed elderly patients who underwent TLIF at a single institution between 2016 and 2021. Patients diagnosed with PUR during hospitalization were identified. GNRI was calculated based on body weight and preoperative serum albumin levels. Multivariate logistic regression analysis was used to determine the association between preoperative GNRI and PUR. Receiver operating characteristic (ROC) curve analysis was conducted to determine the optimal GNRI cutoff value for predicting PUR.
resultsA total of 294 patients met the inclusion criteria. PUR occurred in 47 patients (15.9%). The GNRI was significantly lower in the PUR group compared to the non-PUR group (93.3 ± 7.49 vs. 101.6 ± 6.59, P < 0.001). Multivariate logistic regression analysis confirmed that a lower GNRI independently predicted PUR (OR: 0.763; 95% CI: 0.699-0.834, p < 0.001). ROC analysis identified a GNRI cutoff value of 94.7, with an area under the curve (AUC) of 0.799 ± 0.037.
conclusionLower GNRI is significantly associated with increased risk of PUR following TLIF. GNRI may serve as a useful, independent predictor of PUR risk.
