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
objectivesThis study aims to establish evidence-based cut-off values of the Mini Nutritional Assessment-Short Form (MNA-SF) for predicting key postoperative outcomes including 60-day mortality, complications, and functional ambulation recovery in a broader cohort of elderly hip fracture patients. PATIENTS AND
methodsBetween January 2022 and July 2024, a total of 183 elderly hip fracture patients (57 males, 126 females; mean age: 82.7 ± 7.6 years; range, 65 to 101 years) who received surgical treatment were included. The patients encompassed the full spectrum of nutritional status (from well-nourished to malnourished). Logistic regression assessed the associations between preoperative MNA-SF scores (as a continuous variable) and 60-day mortality, complication rates, and gait status. Receiver operating characteristic (ROC) curves were used to identify optimal outcome-predictive cut-off values in the total cohort.
resultsIn the overall population, 78 of 183 (42.6%) patients developed postoperative complications, with 94 total complication events documented-34 orthopedic-specific complications (36.2%, including eight surgical site infections, four implant-related complications, and 22 affected limb function-related complications) and 60 systemic complications (63.8%, including 25 pulmonary infections, 26 urinary tract infections, 18 deep venous thromboses, 22 delirium cases, and three pressure sores). Lower MNA-SF scores were significantly correlated with increased risks of 60-day mortality and postoperative complications, but not with gait recovery. The optimal predictive cut-off for mortality was ≤ 7 (adjusted odds ratio [OR] = 0.72, 95% confidence interval [CI] 0.57-0.90; sensitivity 73.7%, specificity 64.0%; area under the curve [AUC] = 0.708). For complications, the optimal cut-off was ≤ 8 (adjusted OR = 0.82, 95% CI 0.72-0.93; sensitivity 74.4%, specificity 51.6%; AUC = 0.645).
conclusionThe MNA-SF is a valuable tool for preoperative risk stratification in geriatric hip fracture patients. We propose novel, evidence-based cut-off values (≤ 7 for mortality and ≤ 8 for complications) derived from a comprehensive cohort, which provide clinically actionable thresholds for identifying high-risk patients most likely to benefit from targeted nutritional and medical interventions.
