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

Women with primary mitral insufficiency have a smaller regurgitant volume at the same regurgitant fraction than men. We hypothesized that normalizing regurgitant volume with left ventricular end-diastolic volume or allometric scaling would eliminate the difference in regurgitant volume between women and men. The study cohort consisted of 101 patients with mitral valve prolapse undergoing cardiac MRI. Descriptive statistics and linear regression were performed to assess differences between sexes. Of the 101 patients, 46 (46%) were women. Women had a significantly smaller left and right ventricular end-diastolic volume, end-systolic volume, and stroke volume. While there was no difference in regurgitant fraction between women and men (34 ± 13% vs. 35 ± 14%; p = 0.71), women had a significantly smaller regurgitant volume (36 ± 18 ml vs. 49 ± 26 ml; p = 0.005). The slope-intercept relationship between regurgitant fraction and regurgitant volume revealed unique slopes and y-intercept values for men and women (p-value < 0.0001).
