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: This study aimed to examine whether the ability to open a canned beverage can be associated with sarcopenia and to determine whether beverage can-opening status could serve as a simple screening indicator for sarcopenia. Methods: A cross-sectional study was conducted among 109 older adults requiring long-term care/support attending daycare rehabilitation services (81.1 ± 6.9 years; 55 men, 54 women). Participants were instructed to open a stay-on-tab beverage can while sitting and were classified into Success or Failure groups according to single-attempt performance. Handgrip strength and skeletal muscle mass index (SMI) were measured to diagnose sarcopenia according to the Asian Working Group for Sarcopenia 2025 criteria. Logistic regression analyses were performed to examine the associations between sarcopenia, handgrip strength, SMI, and beverage can-opening status after adjusting for age, sex, body mass index, Barthel Index, and Charlson Comorbidity Index. Screening performance for the inability to open a can for sarcopenia was evaluated. Results: The Success and Failure groups comprised 78 and 31 participants, respectively. Can-opening failure was significantly associated with sarcopenia (odds ratio, 4.5; 95% confidence interval, 1.4-14.1; P = 0.009), and similar associations were observed for low handgrip strength and low SMI. The inability to open a canned beverage demonstrated a moderate discriminatory ability for sarcopenia (area under the curve, 0.62; sensitivity, 42.2%; specificity, 81.3%; P = 0.038). Conclusions: Beverage can-opening status may reflect sarcopenia status. Difficulty in opening cans, an everyday sign readily noticed by individuals and family members, may facilitate early detection of sarcopenia without specialized measurements.
