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
introductionExcess body weight can underestimate undernutrition in hospitalized patients. Performing standardised Nutrition-Focused Physical Examination may reduce subjectivity. This study aimed to assess the concurrent validity of the Systematic Nutritional Clinical Assessment tool and its ability to identify nutritional depletion in patients with excess body weight.
methodsThis cross-sectional study included adult patients hospitalized in two Brazilian regions. Within 48 hours of admission, patients underwent anthropometric assessment, handgrip strength, Subjective Global Assessment or Patient-Generated Subjective Global Assessment, and Systematic Nutritional Clinical Assessment.
resultsA total of 412 patients were included (57.6 ± 14.3 years; 58.7% male), from oncology (29.1%), hepatology (28.6%), cardiology (24.0%), and nephrology (18.2%). Undernutrition frequency was 51.4% by Subjective Global Assessment/Patient-Generated Subjective Global Assessment and 35.7% by Systematic Nutritional Clinical Assessment. The Systematic Nutritional Clinical Assessment showed moderate agreement with the Subjective Global Assessment (k = 0.572; p < 0.001), high diagnostic accuracy (AUROC 0.886), 63.7% sensitivity, and 94% specificity. In the subgroup of patients with excess body weight, the post-test probability for positive results increased from 31.7% to 93.1%. The biceps and triceps compartment stood out for high sensitivity (83.0%), while the dorsum of hands and interosseous muscles stood out for high specificity (87.5%).
conclusionThe Systematic Nutritional Clinical Assessment is shown to be a reliable instrument for confirming nutritional depletion in patients with and without excess body weight. When a simplified physical examination is required during nutritional assessment, the evaluation of the dorsum of hands and interosseous muscles showed the highest specificity.
