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

backgroundPatients with isolated tricuspid regurgitation (TR) in the absence of left-sided valvular dysfunction are often managed nonoperatively.

objectivesThe purpose of this study was to assess the impact of surgery for isolated TR, comparing survival for isolated severe TR patients who underwent surgery with those who did not.

methodsA longitudinal echocardiography database was used to perform a retrospective analysis of 3,276 adult patients with isolated severe TR from November 2001 to March 2016. All-cause mortality for patients who underwent surgery versus those who did not was analyzed in the entire cohort and in a propensity-matched sample. To assess the possibility of immortal time bias, the analysis was performed considering time from diagnosis to surgery as a time-dependent covariate.

resultsOf 3,276 patients with isolated severe TR, 171 (5%) underwent tricuspid valve surgery, including 143 (84%) repairs and 28 (16%) replacements. The remaining 3,105 (95%) patients were medically managed. When considering surgery as a time-dependent covariate in a propensity-matched sample, there was no difference in overall survival between patients who received medical versus surgical therapy (hazard ratio: 1.34; 95% confidence interval: 0.78 to 2.30; p = 0.288). In the subgroup that underwent surgery, there was no difference in survival between tricuspid repair versus replacement (hazard ratio: 1.53; 95% confidence interval: 0.74 to 3.17; p = 0.254).

conclusionsIn patients with isolated severe TR, surgery is not associated with improved long-term survival compared to medical management alone after accounting for immortal time bias.
