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

backgroundThe extent of pericardiectomy is an important issue in constrictive pericarditis but its impact on long-term outcomes has been rarely reported. We compared long-term results of radical pericardiectomy with conventional phrenic to phrenic pericardiectomy.

methodsNinety patients who underwent pericardiectomies between February 1995 and April 2015 were reviewed retrospectively. They were classified into conventional (n = 37) and radical (n = 53) groups according to pericardiectomy being performed anterior or posterior to the phrenic nerves, respectively. The follow-up duration at outpatient clinic was 37.6 (11.7, 86.6) months and the survival data until 91.6 (54.5, 147.0) months were obtained. The last echocardiographies were done at 22.4 (4.35, 60.85) months.

resultsThe early mortality rate was 4.4% (4/90). They all belonged to the conventional group and died of low cardiac output syndrome. The survival rate was higher in the radical group (P = .032, 74.7 ± 9.2% versus 50.4 ± 11.9% in 20 years). NYHA class of both groups had recovered until the last follow-up but the radical group showed better recovery (P < .001). The conventional pericardiectomy (HR = 6.181; 95% CI (1.042, 36.656)), redosternotomy (HR = 6.441; 95% CI (1.224, 33.889) and preoperative grade of tricuspid regurgitation (HR = 15.003; 95% CI (1.099, 204.894) were associated with late mortality. Right ventricular systolic pressure decreased, and pericardial thickening resolved only in the radical group with significant intergroup differences as time went on. Tricuspid regurgitation worsened after the operation in both groups, but it deteriorated more in the conventional group. However, it improved over time in the radical group.

conclusionsRadical pericardiectomy led to greater improvement in right ventricular systolic pressure and lesser deterioration of tricuspid regurgitation with the passage of time than did the conventional procedure. Conventional pericardiectomy and preoperative higher grade tricuspid regurgitation were associated with long-term mortality.
