1 · What the graph read from it

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.

2 · The registry

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

backgroundMalondialdehyde (MDA) is generated during lipid peroxidation as in oxidized low-density lipoprotein, but antibodies against oxidized low-density lipoprotein show variable results in clinical studies. We therefore studied the risk of cardiovascular disease (CVD) associated with IgM antibodies against MDA conjugated with human albumin (anti-MDA). METHODS AND

resultsIn a 5- to 7-year follow-up of 60-year-old men and women from Stockholm County previously screened for cardiovascular risk factors (2039 men, 2193 women), 209 incident CVD cases (defined as new events of coronary heart disease, fatal and nonfatal myocardial infarction, ischemic stroke, and hospitalization for angina pectoris) and 620 age- and sex-matched controls were tested for IgM anti-MDA by ELISA. Antibody peptide/protein characterization was done using a proteomics de novo sequencing approach. After adjustment for smoking, body-mass index, type 2 diabetes mellitus, hyperlipidemia, and hypertension, an increased CVD risk was observed in the low IgM anti-MDA percentiles (below 10th and 25th) (odds ratio and 95% CI: 2.0; 1.19-3.36 and 1.67; 1.16-2.41, respectively). Anti-MDA above the 66th percentile was associated with a decreased CVD risk (odds ratio 0.68; CI: 0.48-0.98). After stratification by sex, associations were only present among men. IgM anti-MDA levels were lower among cases (median [interquartile range]: 141.0 [112.7-164.3] versus 147.4 [123.5-169.6]; P=0.0177), even more so among men (130.6 [107.7-155.3] versus 143.0 [120.1-165.2]; P=0.001). The IgM anti-MDA variable region profiles are distinctly different and also more homologous in their content (correlates strongly with fewer peptides) than control antibodies (not binding MDA).

conclusionsIgM anti-MDA is a protection marker for CVD. This finding could have diagnostic and therapeutic implications.
