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
backgroundThe purpose of this study was to explore the associations of the triglyceride-glucose (TyG) index and its clinically relevant derivatives with handgrip strength asymmetry (HGS-A) in a nationally representative cohort of older adults in China.
methodsHere, we used the data of participants aged between 45 and 80 years who were from wave 2015 of the China Health and Retirement Longitudinal Study (CHARLS). HGS asymmetry was defined as the ratio of nondominant to dominant HGS, categorized into the following four groups: 0.9-1.1 (nonasymmetry), 0.80 ≤ ratio < 0.90 or 1.10 < ratio ≤ 1.20 (mild asymmetry), 0.70 ≤ ratio < 0.80 or 1.20 < ratio ≤ 1.30 (moderate asymmetry) and ratio < 0.70 or ratio > 1.30 (severe asymmetry). Multivariable logistic regression was adopted to assess the association of TyG, TyG-body mass index (TyG-BMI) and TyG-waist-to-height ratio (TyG-WHtR) with HGS asymmetry.
resultsA total of 3521 middle-aged and elderly individuals (mean age: 59.74 years; 47.9% male) were included, with the mean TyG of 8.733 ± 0.660, mean TyG-BMI of 243.559 ± 31.120, mean TyG-WHtR of 4.702 ± 0.733. The mean HGS ratio was 0.97 ± 0.16, and participants were classified into the following four groups: nonasymmetry (n = 2174), mild asymmetry (n = 972), moderate asymmetry (n = 237) and severe asymmetry (n = 138). Overall, the prevalence of HGS asymmetry was 38.26%. The prevalence of severe asymmetry increased across TyG quartiles from 3.7% to 4.5% (Q1-Q4, p = 0.018). TyG-WHtR showed increasing prevalence of severe asymmetry from 4.9% to 5.1% across quartiles (p = 0.042). For TyG-BMI, it exhibited an inverse relationship with severe asymmetry prevalence decreasing from 5.3% to 2.4%. Multivariable-adjusted models confirmed that TyG-WHtR demonstrated the strongest effect size with Q2 and Q3 associated with significantly increased odds of asymmetry (OR = 1.507 and 1.437, respectively). TyG-BMI showed a protective effect with higher quartiles associated with reduced odds (Q2-Q4 OR range: 0.973-0.984).
conclusionsHigher levels of TyG-WHtR and lower levels of TyG-BMI are both associated with a higher prevalence and severity of HGS asymmetry in middle-aged and older Chinese adults.
