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
purposeTo investigate the association between metabolic syndrome (MetS) and nocturia in a nationally representative U.S. adult population, focusing on individual metabolic components and subgroup differences by age and sex. MATERIALS AND
methodsWe analyzed data from 8,518 adults aged ≥20 years who participated in the National Health and Nutrition Examination Survey from 2005 to 2014. Nocturia was defined as ≥2 nighttime voids. MetS was defined by the presence of ≥3 National Cholesterol Education Program Adult Treatment Panel III criteria. Multivariate logistic regression and restricted cubic spline (RCS) analyses were used to assess associations, adjusting for demographic and behavioral covariates.
resultsOverall, 23.3% of participants had MetS and 29.6% reported nocturia. MetS was independently associated with nocturia (adjusted odds ratio [OR] 1.387, 95% confidence interval 1.236-1.557). A dose-response relationship was observed, with nocturia risk increasing. Central obesity (OR 1.564), elevated fasting glucose (OR 1.397), and elevated blood pressure (OR 1.311) showed the strongest associations. RCS analyses revealed linear associations for waist circumference and systolic blood pressure, and nonlinear associations for diastolic blood pressure and glucose. Sex-specific analyses revealed distinct nonlinear patterns, particularly for waist circumference among male participants and triglyceride levels among female participants. The association remained consistent across most age and sex groups, except in males aged 20-40 years.
conclusionsMetS and its components are independently associated with nocturia. The observed sex-specific differences suggest that metabolic contributors to nocturia may differ by sex supporting nocturia as a potential clinical marker of underlying cardiometabolic dysfunction.
