Independent predictive role of nutritional markers in kidney function decline and mortality in diabetes.

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
Background: Malnutrition and chronic inflammation are common in chronic kidney disease (CKD) and contribute to disease progression and mortality. While the prognostic nutritional index (PNI), geriatric nutritional risk index (GNRI), and controlling nutritional status (CONUT) scores assess nutritional status, their predictive values for CKD progression and mortality in individuals with diabetes, particularly independent of tumor necrosis factor receptor 2 (TNFR2), remains unclear. This study aimed to evaluate whether these markers predict outcomes beyond TNFR2. Subjects/methods: We analyzed 640 individuals with diabetes, stratified by PNI quartiles (Q1 vs. Q2-4). Serum TNFR2 was measured using enzyme-linked immunosorbent assay. Nutritional status was assessed using PNI, GNRI, and CONUT scores. Cox proportional hazards models adjusted for covariates including TNFR2 examined associations between nutritional markers and a kidney event (≥30 % decline in estimated glomerular filtration rate), mortality, and a composite outcome. Results: The mean age was 65 years; 53.9 % were male. Over median follow-ups of 5.3 and 5.4-years, 75 (11.7 %) experienced a kidney event and 44 (6.9 %) died. A total of 112 (17.5 %) experienced the composite outcome. All three markers were independently associated with a kidney event (PNI: hazard ratio [HR], 1.84; 95 % confidence interval [CI], 1.13-3.02) and a composite outcome (PNI: HR, 1.94; 95 % CI, 1.30-2.89). GNRI was the only marker independently associated with mortality (HR, 2.90; 95 % CI, 1.56-5.37). Conclusions: PNI, GNRI, and CONUT scores strongly predict adverse outcomes in diabetes, emphasizing the importance of nutritional evaluation. Targeted nutritional interventions may improve prognosis.
