Does weightbearing status impact mortality and other complications in hip fracture patients when accounting for frailty?

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
Aims: The aim of this study was to analyze the risk of mortality and other postoperative complications following restricted weightbearing in geriatric patients who undergo fixation of a hip fracture, while accurately controlling for patient frailty. Methods: The National Surgical Quality Improvement Program (NSQIP) database January 2016 to December 2020 was queried for operatively treated hip fractures in patients aged ≥ 60 years using Current Procedural Terminology (CPT) codes (n = 53,959). Logistic regressions and receiver operating characteristic (ROC) curve analysis were conducted to determine the frailty measure which best predicts 30-day mortality among American Society of Anesthesiologists grade (ASA), five-factor modified Fraility Index (mFI-5), and Risk Analysis Index Recalibrated Version (RAI-Rev). The effect of weightbearing on 30-day mortality, and severe (SAE) and minor (MAE) adverse events, was assessed using logistic regressions while controlling for the selected frailty measure and other relevant patient characteristics. Results: A total of 53,959 patients met the inclusion criteria, and 36,177 patients (67%) were weightbearing as tolerated postoperatively. Under ROC curve, the only discriminatory performance was by RAI-Rev in 30-day mortality. Controlling for RAI-Rev, age, sex, BMI, functional status, and CPT, weightbearing patients had a 42% lower odds of 30-day mortality (p < 0.001), a 31% lower odds of a SAE (p < 0.001), and a 24% lower odds of a MAE (p < 0.001) in comparison to non-weightbearing patients. Conclusion: Geriatric hip fractures are prevalent in patients with varying degrees of health. RAI-Rev is a better predictor of postoperative mortality than ASA grade and mFI-5, and should be used in evaluating the risk of geriatric hip fractures. Postoperative weightbearing is associated with significant reductions in complications for geriatric hip fracture patients, even while controlling for frailty. Our findings suggest that postoperative weightbearing after surgical fixation of geriatric hip fractures should be encouraged for able patients.
