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
objectiveChronic venous disease is a highly prevalent condition with significant morbidity. Although there is a well-documented predominance of chronic venous disease among women, the differences in surgical treatment based on sex, especially in low- and middle-income countries, are not well understood. The aim of this study was to investigate these disparities within Brazil's public healthcare system.
methodsThis cross-sectional study analyzed all varicose vein surgeries (n=1,114,625) performed in the public sector from 2007 to 2024. Data were extracted from the national open database (Sistema de Informações HospitalaresDepartamento de Informática do Sistema Único de Saúde (Department of Informatics of the Unified Health System). We compared demographics, procedural and mortality rates, age at surgery, length of hospital stays, and patterns of travel for surgery between the sexes.
resultsWomen constituted most of the procedures (80.5%). Men underwent bilateral surgery at a significantly older median age than women (49 vs. 47 years, p<0.01). Men were more likely to travel between cities (38.89 vs. 37.22%, p<0.01), while women traveled more between states (0.35 vs. 0.39%, p<0.021). Mortality rates were low for both sexes, but higher for men (0.0197 vs. 0.0023%, p<0.01).
conclusionThis study reveals significant gender disparities in the surgical treatment of varicose veins in Brazil, extending beyond mere prevalence to include differences in the age at which intervention occurs and geographic access patterns. The findings suggest that biological factors alone cannot account for these disparities, highlighting that healthcare-seeking behaviors, mortality rates, and structural inequities also play a crucial role. Further qualitative research is needed to elucidate the underlying motivations for these differences and to guide the development of more equitable healthcare policies.
