1 · What the graph read from it

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.

2 · The registry

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

Objective: Phase angle (PhA) obtained through bioimpedance analysis has been linked to mortality and malnutrition in dialysis patients. However, it remains unclear whether PhA is associated with renal prognosis in non-dialysis CKD patients. Methods: Two thousand two hundred two CKD patients were enrolled in the SMP-CKD cohort, Guangdong Provincial Hospital of Traditional Chinese Medicine from July 1, 2015 to May 31, 2024. Participants undertook bioimpedance measures, and the correlation between PhA and renal endpoint was analyzed. Analytical approaches include Cox proportional hazards analysis and group-based trajectory modeling. Composite outcome is defined as the first occurrence of >30% decline or <5 mL/min/1.73m Results: During a mean follow-up of time 2.5 years, 570(25.9%) participants reached the composite endpoint. In the multivariable Cox regression model, subjects belonging to higher quartiles of phase angle presented with a decreased risk of poor prognosis, showing 29 and 38% risk reductions in Q3 (aHR 0.71, 95%CI 0.55-0.93) and Q4 (aHR 0.62, 0.45-0.85) versus Q1 (both Conclusion: Phase angle could be useful in determining nutritional status of CKD patients, lower phase angle is an independent risk factor for poor prognosis in CKD patients.
