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 impact of aortic valvular resistance (VR) on the degree of post-transcatheter aortic valve replacement (TAVR) aortic regurgitation (AR) remains unclear. The objective of the study was to investigate the relationship between VR and paravalvular AR after TAVR.

methodsBetween August 2007 and December 2015, 708 TAVR patients had sufficient data to calculate VR before the intervention and were eligible for the present analysis. The patient population was dichotomized according to VR. The association between VR and post-TAVR AR was separately assessed by prosthesis type.

resultsAmong patients with low VR (LVR; < 238 dynes/cm

conclusionsHVR is associated with a nearly 2.5-fold increased risk of moderate or greater post-TAVR AR and is an independent predictor of post-TAVR AR.
