Association Between the Phase Angle and Function Recovery in Patients With Hip Fractures.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundPatients with hip fractures frequently present with malnutrition, and proper nutritional management is recognized as an important factor in their clinical care.
objectiveWe aimed to clarify whether the preoperative phase angle could predict postoperative functional recovery and to identify the impact of undernutrition on clinical outcomes in patients with hip fractures.
methodsFor 100 hip fracture patients, serum albumin level and muscle mass on the admission day were recorded. Muscle mass was estimated using plain computed tomography (CT) images with the skeletal muscle index (SMI). All participants were subjected to bioelectrical impedance analysis (BIA), and the phase angle was calculated at admission. Functional Independence Measure (FIM) scores on admission and at two weeks postoperatively and ΔFIM (the difference between the FIM score on admission and the score at two weeks postoperatively) were determined. Correlations among the phase angle, serum albumin level, SMI, and FIM scores were assessed.
resultPositive correlations were observed between the phase angle with both serum albumin level at admission (R=0.53, p<0.001) and SMI (R=0.43, p<0.001). Serum albumin level at admission and the phase angle were positively correlated with both the FIM score at two weeks postoperatively and ΔFIM. From multiple regression analysis with the FIM score at two weeks postoperatively or ΔFIM as the dependent variable, and the phase angle, serum albumin level at admission, and SMI as three independent variables, only the phase angle showed significant correlations with the FIM score at two weeks postoperatively (p<0.001) and ΔFIM (p<0.05).
conclusionsThe preoperative phase angle could predict postoperative functional recovery and identify the impact of undernutrition and sarcopenia on clinical outcomes in patients with hip fractures.
