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

Right ventricular (RV) dysfunction is an indication for tricuspid valve (TV) surgery in patients with severe isolated tricuspid regurgitation (TR). Postoperative RV dysfunction is associated with poor outcome; however, the longitudinal changes in RV function before and after surgery have not been established. We retrospectively analyzed 24 patients who underwent TV surgery for isolated severe TR. For assessing RV systolic function, we measured the RV fractional area change (RVFAC) at baseline, and 1 (immediate) and 4-20 (late) months after surgery. We divided patients into 2 groups according to the RVFAC late after surgery (<35%, post-op. reduced; and ≥35%, post-op. preserved). The mean RVFAC was significantly decreased immediately after surgery compared to baseline (41.5 ± 10.1% vs. 32.2 ± 9.6%; p < 0.001). The RVFAC reduction was still observed late after surgery (35.5 ± 7.4%; p = 0.002). Of 24 patients, 12 patients (50%) had preserved RV systolic function late after surgery. Although there was no significant difference in the preoperative RVFAC between the 2 groups, the preoperative RV end-systolic area (RVESA) /body surface area (BSA) was significantly less in the post-op. preserved RV systolic function group (13.8 ± 4.3 cm
