Phase Angle as a Predictor of Walking Independence in Patients Undergoing Stroke Rehabilitation: A Preliminary Study.
Article in Physical therapy research, 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
Objectives: This study examined the relationship between phase angle (PhA), an indicator of muscle quality, and independent walking in stroke patients. The objective was to determine the predictive value of a PhA at admission for walking independence at discharge. Methods: This study included 220 stroke patients (121 males, 99 females), categorized based on their functional independence measure (FIM) mobility scores at discharge: independent (FIM ≥6; n = 100) and dependent (FIM ≤5; n = 120). Logistic regression analysis assessed whether PhA at admission predicted ambulatory independence at discharge. Additionally, receiver-operating characteristic curve analysis determined optimal cutoff values. Results: Logistic regression analysis showed that PhA at admission and the National Institutes of Health Stroke Scale (NIHSS) were significant predictors of independent walking. The optimal cutoff values for PhA were determined to be 4.35° for men and 4.1° for women. Similarly, the cutoff scores for the NIHSS were 7.5 points for men and 5.5 points for women. Conclusions: In stroke patients, PhA and NIHSS at admission were significantly associated with ambulatory independence at discharge. Evaluation of PhA and NIHSS at admission may be useful for more accurate prediction of gait outcomes.
