The Relationship Between Iron Status and Atherosclerotic Cardiovascular Disease Risk in Non-anemic Patients Without a History of Cardiovascular Diseases: A Cross-Sectional Study.

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
Iron deficiency (ID) and iron status in non-anemic patients with atherosclerotic cardiovascular disease (ASCVD) risk without a history of cardiovascular diseases is still weakly explored. In this study, the authors evaluated the most common ID definitions in this group of patients. A total of 533 participants from the National Health and Nutrition Examination Survey (NHANES) were collected from 2005-2006, 2017-2018, and 2017-2020 records. Participants were divided according to their ASCVD risk score to the following groups: low (n=168, 32%), borderline (n=43, 8%), intermediate (n=200, 37%), and high (n=122, 23%). There was a higher prevalence of ID in low- and borderline-risk groups in contrast to intermediate- and high-risk groups. Higher serum ferritin concentrations were observed in groups with a greater ASCVD risk score. Transferrin saturation (TSAT) was comparable in all ASCVD categories. Lack of ID, defined by three different guidelines that are mainly based on serum ferritin levels, predisposed to a higher ASCVD risk category. Normal iron status, defined by these three guidelines, was positively associated with the male gender. The opposite association was observed for non-Hispanic Whites. The analyzed criteria of ID, based mostly on serum ferritin levels, demonstrated limited usefulness in patients with increased ASCVD risk. Further studies should be done to determine proper ID diagnostic criteria in non-anemic patients without a previous cardiovascular history with elevated ASCVD risk.
