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
backgroundThis study aimed to examine the association between branched-chain amino acids/branched-chain α-keto acids (BCAAs/BCKAs) and adipose tissue insulin resistance (Adipo-IR) in patients with type 2 diabetes mellitus (T2DM).
methodsA total of 506 patients with T2DM were included in this cross-sectional study. Participants were categorized into two groups based on Adipo-IR levels (non-Adipo-IR: Adipo-IR<7.68; Adipo-IR: Adipo-IR ≥ 7.68). Serum BCAA/BCKA concentrations were measured using ELISA kits. Correlations between BCAAs/BCKAs and Adipo-IR or HOMA-IR were evaluated using Spearman correlation analysis. Binary logistic regression was used to examine the associations of BCKAs with both indices of insulin resistance.
resultsMedian serum BCKA levels were significantly higher in the Adipo-IR group than in the non-Adipo-IR (128.27 vs. 121.16, p < 0.001), while there was no significant difference in median serum BCAA levels between the two groups (2.54 vs. 2.52, p = 0.714). BCKAs were positively correlated with both Adipo-IR and HOMA-IR (both p < 0.01), and the association with Adipo-IR was stronger. Binary logistic regression analysis revealed that BCKAs were associated with Adipo-IR regardless of adjustment for influencing factors, with increasing odds ratios across BCKAs quartiles (p for trend < 0.01). However, after adjusting for covariates, the association between BCKAs and HOMA-IR was no longer significant.
conclusionsSerum BCKA levels were elevated in T2DM patients with Adipo-IR and were more strongly correlated with Adipo-IR than HOMA-IR. BCKAs may serve as sensitive biomarkers for Adipo-IR. Consequently, we would promote their clinical usage in the early screening of individuals with obesity, insulin resistance and a high risk of T2DM.
