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: Pregnancies affected by metabolic dysfunction-associated steatotic liver disease (MASLD) have tripled over the past decade. However, tools to assess MASLD in pregnancy are limited to ultrasound, which has shown poor reproducibility and does not provide quantitative data. Current guidelines for non-pregnant adults recommend the use of vibration-controlled transient elastography (VCTE) with controlled attenuation parameter (CAP) for staging and monitoring of liver disease. Given the limitations of ultrasound and the scarcity of data on use of VCTE in pregnancy, we evaluated the use of VCTE to determine the prevalence of MASLD in a pregnant population. Also, we determined the association between increased VCTE-derived CAP scores and adverse pregnancy outcomes. Methods: Pregnant individuals with no history of liver disease presenting for routine prenatal care were followed up throughout pregnancy and had VCTE-derived CAP assessments at 24-32 weeks of gestation. Postpartum VCTE-derived CAP assessments were also obtained. Multivariable logistic regression was performed to evaluate for predictors of liver steatosis (CAP) and liver stiffness (liver stiffness measurement [LSM]) and association with adverse pregnancy outcomes. Findings: 247 pregnant individuals (mean age 30·0 years [SD 6·0]; mean pre-pregnancy BMI 30 kg/m² [SD 6·1]) had VCTE assessments during pregnancy. The prevalence of MASLD was 11% (95% CI 7-15%) based on VCTE-derived CAP and evidence of cardiometabolic disease. On multivariable analyses, pre-pregnancy BMI was a predictor of increased CAP scores (odds ratio [OR] 1·13, 95% CI 1·05-1·22), whereas polycystic ovary syndrome was a predictor of liver stiffness (4·79, 1·11-20·65). Increased CAP scores were associated with the development of intrahepatic cholestasis of pregnancy (OR 12·07, 95% CI 1·97-73·87) and LSM with large for gestational age (8·33, 1·02-67·87). Of those with postpartum follow-up (n=41), 24 (59%) individuals had an increase in postpartum CAP scores by at least 10%. Interpretation: We found a high prevalence of MASLD in pregnancy that might not have otherwise been diagnosed. Pre-pregnancy BMI was the strongest predictor of liver steatosis and polycystic ovary syndrome for liver stiffness. Increased VCTE-derived CAP assessment results were associated with certain adverse pregnancy outcomes; however, this result should be interpreted with caution given the small sample size. VCTE-derived CAP assessment could be a useful non-invasive bedside tool to diagnose and assess liver disease in the obstetric context. The prognostic value of VCTE-derived CAP requires further investigation.
