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

backgroundPrevious studies have reported beneficial effects of a Mediterranean diet rich in monounsaturated fatty acids (MUFAs) on coronary artery disease (CAD) risk. However, these findings remain inconsistent because some experimental studies have suggested atherogenic and lipotoxicity effects of long-chain and very-long-chain MUFAs on cardiomyocytes.

objectiveWe examined whether red blood cell (RBC) long-chain and very-long-chain MUFAs are associated with risk of CAD in the Physicians' Health Study.

designThe ancillary study used a prospective nested case-control design to select 1000 cases of incident CAD and 1000 control subjects matched for age, year of birth, and time of blood collection. RBC MUFAs were measured by using gas chromatography, and CAD was validated by an endpoint committee. Conditional logistic regression was used to estimate RRs.

resultsThe mean (±SD) age was 68.7 ± 8.7 y. In a multivariable model that was controlled for matching factors and established CAD risk factors and RBC saturated and omega-3 (n-3) fatty acids, ORs for CAD associated with each SD increase of 20:1n-9 and log 22:1n-9 were 0.89 (95% CI: 0.80, 1.00; P = 0.0441) and 0.83 (95% CI: 0.72, 0.95; P = 0.0086). However, only the 22:1n-9-CAD relation remained statistically significant after Bonferroni correction (P < 0.0125). RBC cis 18:1n-9 and 24:1n-9 were not associated with CAD risk.

conclusionOur data suggest an inverse association of RBC 22:1n-9 but not 20:1n-9, 18:1n-9, or 24:1n-9 with CAD risk after Bonferroni correction in the Physicians' Health Study.
