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

Background: Patients with schizophrenia have a high prevalence of sarcopenic obesity (SO) (19.2%), largely due to antipsychotic use and sedentary lifestyle. Conventional diagnostic techniques (e.g., dual-energy X-ray absorptiometry [DXA]) are limited by their cost and complexity. Objective: To evaluate thenar muscle ultrasound (thickness and echo intensity) combined with sex for SO screening and its association with pneumonia and falls. Methods: A total of 490 patients with stable schizophrenia underwent bilateral thenar ultrasonography. SO was diagnosed according to the Asian Working Group for Sarcopenia (AWGS) 2019 criteria (muscle mass, grip strength, gait speed) and the Japanese obesity consensus (body fat ≥20% in males, ≥30% in females, or visceral fat ≥100 cm²). Diagnostic efficacy (ROC analysis) and adverse outcomes were assessed. Results: Patients with SO (n=94) had significantly reduced thenar muscle thickness (left: 13.81 vs. 14.75 mm, p<0.001; right: 14.83 vs. 15.96 mm, p<0.001) and higher echo intensity (left: 39.57 vs. 35.66, p=0.002; right: 38.52 vs. 34.51, p<0.001) compared with patients without SO (n=396). A model combining right thenar thickness, echo intensity, and gender achieved the best diagnostic performance (AUC = 0.805, sensitivity=73.2%, specificity=76.3%). SO was significantly associated with increased fall risk (adjusted OR = 2.889, p=0.002) and pneumonia (unadjusted OR = 2.175, p=0.038). Conclusion: Thenar ultrasound combined with sex provides an efficient tool for SO screening (AUC>0.8) in patients with schizophrenia, supporting early intervention to reduce adverse outcomes.
