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
Steatotic liver disease (SLD)-a term encompassing nonalcoholic fatty liver disease (NAFLD), metabolic-associated fatty liver disease (MAFLD), and metabolic dysfunction-associated steatotic liver disease (MASLD)-and chronic kidney disease (CKD) are major global health concerns. Metabolic factors, including obesity, type 2 diabetes, hypertension, and dyslipidemia, are integral to the definitions of MAFLD and MASLD and may confound their association with CKD. This study aimed to update a meta-analysis on the association between SLD and CKD risk and to conduct a two-sample Mendelian randomization (MR) analysis to explore the causal roles of SLD and metabolic factors in CKD. We systematically searched PubMed, Embase, and Web of Science up to November 5, 2024, for eligible studies. Random-effects models were used to pool odds ratios (ORs) with 95% confidence intervals (CIs). Two-sample MR was performed using the inverse-variance weighted (IVW) method as the primary model, with additional methods applied for sensitivity analyses. A total of 34 studies involving 3,783,136 participants were included in the meta-analysis. The results demonstrated significant positive associations between MAFLD, NAFLD, and MASLD with CKD (MAFLD: OR 1.41 [1.07-1.84], RR 1.64 [1.39-1.94], HR 1.64 [1.39-1.94]; NAFLD: OR 1.19 [1.08-1.31], RR 1.66 [1.45-1.91], HR 1.43 [1.31-1.55]; MASLD: HR 1.34 [1.08-1.67]). These findings support a significant association between SLD (MAFLD, NAFLD, and MASLD) and an increased risk of CKD. However, Mendelian randomization (MR) analysis found no causal effect of SLD on CKD risk. In contrast, genetically predicted metabolic factors-including body mass index (BMI), waist circumference, type 2 diabetes, systolic and diastolic blood pressure, triglycerides, and high-density lipoprotein cholesterol-were significantly associated with an increased CKD risk. These findings suggest that metabolic dysfunction, rather than SLD itself, may be the main driver of CKD risk. This underscores the clinical importance of early screening and intervention for metabolic health in patients with SLD to reduce the burden of CKD.
