Rapid Nutritional Screening and Short-Term Prognosis in Advanced Schistosomiasis: A Prospective Cohort Study.
Article in Acta parasitologica, 2026. 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
purposeTo identify an appropriate rapid nutritional screening tool for bedside use, and to determine whether early nutritional risk provide clinically meaningful prognostic information in advanced schistosomiasis.
methodsThis prospective single-center cohort enrolled 436 patients with advanced schistosomiasis. Anthropometric indicators and four nutritional screening and assessment tools (NRS-2002, RFH-NPT, LDUST, and SGA) were applied. Agreement between tools was evaluated using Kappa statistics. Short-term prognosis was defined as adverse outcomes within 4 months. Multivariable and penalized logistic regression models identified prognostic nutritional indicators. Model performance was assessed using receiver operating characteristic curves, calibration, decision curve analysis, and net reclassification improvement. Clinical nomograms were developed.
resultsThe mean age was 63.19 ± 11.19 years and 54.6% were male. Using SGA as reference, LDUST showed the highest sensitivity (100%) and demonstrated favorable screening performance. SGA identified malnutrition in 14.2% of patients, while LDUST classified 50.0% as at nutritional risk. Triceps skinfold thickness (TSF), LDUST-defined risk, and SGA-defined malnutrition were relatively informative nutritional predictors. Models incorporating these measures demonstrated higher prognostic discrimination (AUC = 0.786, 95% CI 0.709–0.862) compared with clinical variables alone (AUC = 0.739, 95% CI 0.655–0.823). Higher TSF was associated with a lower risk of poor outcomes (OR = 0.945, 95% CI 0.895–0.998). Nomograms indicated TSF contributed the greatest prognostic weight among nutritional variables.
conclusionLDUST offers a feasible and sensitive tool for rapid bedside nutritional screening in advanced schistosomiasis. Nutrition-based assessments may provide modest additional prognostic information beyond clinical variables, supporting early risk stratification and targeted nutritional management, particularly in resource-limited settings where disease burden is high.
