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
Background: Recognizing the crucial role of nutritional status in the advancement of diabetic complications, this investigation aimed to evaluate sex-specific disparities concerning the relationship between the Controlling Nutritional Status (CONUT) score and diabetic kidney disease (DKD). Methods: Data obtained from the First Affiliated Hospital of Yangtze University, spanning January 2022 to May 2024, were utilized. The CONUT score was determined utilizing serum albumin (ALB), total cholesterol (TC), and lymphocyte (LYM) count. Sex-specific correlations among CONUT scores and DKD were evaluated using multivariate logistic regression and restricted cubic splines (RCS). Receiver operating characteristic (ROC) curve analysis was employed to ascertain the area under the curve (AUC) for the CONUT score in female participants. Subgroup analyses and interaction assessments were conducted to investigate the influence of the CONUT score within sex-specific subgroups. Results: A total of 1,429 individuals were enrolled. Following adjustment for all covariates, women within the elevated CONUT score group exhibited a 66% augmented odds of DKD [OR = 1.66 (95%CI: 1.08-2.58)]. RCS analysis indicated a linear positive correlation between the CONUT score and the odds of DKD in women (P-non-linear: 0.840). The AUC for the CONUT score in women was 0.700 (95%CI: 0.653-0.748), indicating its potential utility as a risk identification tool for DKD. Subgroup analyses revealed a noteworthy positive correlation between elevated CONUT scores and the odds of DKD among females aged ≥60 years, those with a high school diploma, who smoked, consumed alcohol, were not hypertensive, had hyperlipidemia, or had a high TC/HDL ratio. Conclusion: This study demonstrates sex-specific disparities in the prevalence of DKD associated with elevated CONUT scores. These outcomes underscore the significance of individualized nutritional interventions for females at an elevated odd of DKD.
