A cross-sectional analysis of all vena cava filter placement over 9-years in Brazil: trends and mortality rates in a population of over 200 million.

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
backgroundVenous Thromboembolism (VTE) is a major global health concern, with Vena Cava Filters (VCFs) serving as an alternative to anticoagulation in high-risk patients. Brazil's VCF trends remain understudied, particularly in its dual public-private healthcare system. This database study allows a broad overview of the Brazilian healthcare landscape.
methodsThis cross-sectional nationwide analysis used Brazilian public (SUS/TabNet) and private (ANS/D-TISS) healthcare databases (2015-2023) to assess VCF placement rates, regional disparities, and in-hospital mortality. Data included 21,630 procedures, analyzed via generalized linear models (Gamma/Poisson distributions).
resultsThe private system performed 57% of VCFs (12,323) despite covering only 25% of the population, with a 4.25-fold higher procedure rate per capita than the public system (29.45 vs. 6.42 per-million). Women accounted for 57.8% of recipients. The Southeast region dominated (70% private, 40.5% public), while the North and Midwest had the lowest rates. Mortality rates were comparable (public 6.7% vs. private 7.4%, p = 0.066), peaking during COVID-19. Procedure volumes rose 140% over 9-years, contrasting with declining U.S. trends post-FDA restrictions.
conclusionsBrazil's VCF use reflects systemic disparities, with private-system overrepresentation and regional gaps. This study enables unprecedented insights into large-scale VCF implementation across diverse healthcare subsystems.
