Bioelectrical Impedance Phase Angle and its Relationship with Anthropometric and Body Composition Parameters in Hospitalized Children with Severe Acute Malnutrition: A Longitudinal Follow-up Study.
Observational study in Indian pediatrics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectiveBioelectrical impedance analysis (BIA) measures a parameter known as Phase Angle (PhA) which reflects the cellular health. This study assessed changes in PhA and association with anthropometric and body composition parameters in children with severe acute malnutrition (SAM).
methodsA longitudinal observational follow-up study was conducted among hospitalized children aged 12-59 months with SAM, treated at a Nutrition Rehabilitation Centre. Anthropometry and BIA, including PhA data and analyses, were performed at admission, at discharge, and 11-weeks post-discharge follow-up.
resultsOf the 141 children enrolled, 136 were successfully discharged following treatment of medical complications and stabilization. Of these, 106 (75.2%) completed nutritional rehabilitation and follow-up of 11 weeks. The median (q1, q3) hospital stay was 10 (6, 14) days with mean (SD) daily weight gain of 3.50 (- 1.8) g/kg/day. Lower PhA values were observed in children aged 24-59 months, with edema, and those from low-income households. PhA positively correlated with weight-for-height (WHZ) and body-cell-mass-index, and negatively with extracellular water. There was no significant difference in PhA (at baseline or follow-up) between those who achieved complete cure (30.2%), partial cure (51.9%) or remained SAM (17.9%). A multivariable linear regression model (R
conclusionPhA can be a complementary marker of cellular health and nutritional recovery in SAM children. Standardized reference values are needed to enable its routine clinical use, especially in resource-limited settings.
