First-week postoperative caloric intake predicts mortality, complications and functional recovery in elderly patients with hip fracture and compromised nutritional status.

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
objectiveThis study aimed to evaluate the impact of caloric deficiency during the first postoperative week on 60-day mortality, complication incidence and functional ambulatory recovery in elderly patients with hip fracture who are malnourished or nutritionally at risk.
methodsA prospective observational study included 120 patients with surgically treated hip fracture aged > 65 years with preoperative malnutrition (Mini Nutritional Assessment - Short Form ≤ 11). Caloric intake was calculated using the Harris-Benedict equation, and patients were stratified into two groups: <60% or ≥ 60% of the caloric goals during the first postoperative week. Outcomes included 60-day mortality, postoperative complications (infectious, cardiovascular, delirium) and mobility levels. Logistic regression adjusted for covariates was used for analysis.
resultsThe ≥ 60% caloric intake group exhibited significantly higher 60-day survival (93.98% vs. 72.97%, p = 0.004) and lower complication rates (38.55% vs. 75.68%, p < 0.001) than the < 60% group. Logistic regression analyses verified the reduced mortality risk (odds ratio [OR]: 0.129, 95% confidence interval [CI]: 0.02-0.70) and complication risk (OR: 0.225, 95% CI: 0.09-0.59) in the ≥ 60% group. Additionally, sufficient caloric intake was found to correlate with improved mobility (OR: 3.984, 95% CI: 1.54-10.31).
conclusionOur study demonstrates that insufficient caloric intake during the first postoperative week is associated with elevated mortality risk, higher rates of postoperative complications and delayed functional recovery in elderly patients undergoing hip fracture surgery who are malnourished.
