The association between alpha-1 antitrypsin and B-type natriuretic peptide blood levels in healthy African Americans.
Article in BMC research notes, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveB-type natriuretic peptide (BNP) is a neurohormone primarily secreted from cardiac ventricles in reaction to increased volume and pressure. The plasma level of BNP is used to measure the mechanical function of the heart and the risk of developing chronic obstructive pulmonary disease (COPD). Alpha-1 antitrypsin (AAT) is a glycoprotein that acts as an inhibitor of serine proteases and plays a crucial role in protecting the lungs against potential harm. AAT deficiency also causes COPD. The data on the prevalence of BNP and AAT in African Americans (AA) are limited and inconsistent. No previous studies have investigated whether any association exists between BNP and AAT. We collected fasting blood samples from 114 AA subjects who provided informed consent. The plasma levels of the biomarkers were measured using ELISA.
resultsOur findings revealed a significant negative correlation between AAT and BNP (r=-0.266, p = 0.01) as well as between AAT and TNF-α (r=-0.242, p = 0.01). Sex hormones (estrogen and testosterone) have a significant relationship with the levels of AAT and BNP. Increasing the AAT and reducing the levels of inflammation can lower the levels of BNP, which in turn could help lower the risk of heart disease in the AA population.
