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.

Abstract

backgroundThe risk of atherosclerotic cardiovascular disease (ASCVD) is increased in Rheumatoid Arthritis (RA). Previous research has suggested that lipid metabolism is altered in RA, but research under postprandial conditions is scarce. The aim of this study was to investigate whether women with RA have a different lipemic and inflammatory response to a mixed meal containing red meat compared to women without RA.

methodsTwenty-two women with RA, with modest disease activity, and 22 women without RA matched for age and body mass index (BMI) at the group level consumed a hamburger meal containing ca. 700 kcal (53 E% from fat, 27 E% from carbohydrate). Venous blood was sampled in the fasted state and after 30 min, 1, 2, 3 and 5 h and analysed for lipid species using nuclear magnetic resonance spectroscopy. Postprandial inflammation was measured by interleukin- 6 (IL- 6). The postprandial lipid response was calculated as the incremental area under the curve minimal value, and serial measurements were analysed by repeated measures analysis of variance. Lipid and inflammatory responses were compared by linear regression analysis, adjusted for age, BMI, physical activity, and baseline plasma concentration.

resultsPlasma concentrations of IL- 6, triglycerides (TGs) and very low-density lipoprotein (VLDL) particles increased significantly after the meal compared to baseline within both groups, but no differences were observed between groups. However, the women with RA had a less pronounced response in cholesterol carried in VLDL particles (p = 0.03) and in TGs in the subfraction of VLDL particles with highest density (p = 0.03). No association was found between the response in TGs and IL- 6.

conclusionThis study does not provide compelling evidence for any difference in the lipemic or inflammatory response in women with RA compared with age- and BMI-matched women without RA following ingestion of a mixed, high-fat meal containing red meat. The modest disease activity in women with RA should be considered when interpreting these findings. Subtle group differences found in the lipids carried by VLDL particles warrant further investigation.
