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
Objectives: Sarcopenia and low muscle mass are distinct clinical conditions associated with adverse outcomes after colorectal cancer (CRC) surgery. Due to limited effective screening methods, we evaluated the diagnostic performance of four tools for these conditions in preoperative patients with CRC. Methods: This cross-sectional study included patients aged ≥65 years with stage I-III CRC scheduled for elective surgery. Sarcopenia and low appendicular skeletal muscle mass (ASM) were diagnosed according to the Asian Working Group for Sarcopenia 2019 criteria. Diagnostic performance of calf circumference (CC), SARC-F, SARC-CalF, and the Ishii score was evaluated. Results: Ninety-eight patients (48.0% females, mean age 77.4 ± 6.2 years) were included. Prevalences of low ASM and sarcopenia were 56.1% and 41.8%, respectively. For low ASM, CC demonstrated the highest accuracy (AUC 0.907, sensitivity 80.0%, specificity 86.0%), significantly outperforming SARC-F and SARC-CalF (AUCs 0.617 and 0.854; Conclusions: The Ishii score demonstrated superior diagnostic performance for sarcopenia, underscoring the importance of muscle strength assessment for effective screening.
