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

Background: This study aimed to: (1) assess changes in peripheral skeletal muscle oxygenation during exercise after transcatheter aortic valve implantation (TAVI) in patients with severe aortic stenosis (AS); and (2) identify characteristics of patients who exhibited improved exercise tolerance. Methods and Results: In this single-center prospective study, 20 patients with severe symptomatic AS underwent evaluation before and 1 week after TAVI. Exercise tolerance was assessed using the incremental shuttle walk test (ISWT), and the incremental shuttle walk distance (ISWD) was recorded. Calf muscle oxygenation during the ISWT was continuously measured using near-infrared spectroscopy (NIRS). ISWD increased significantly after TAVI (P<0.01). During the ISWT, the change in oxygenated hemoglobin (∆O Conclusions: Peripheral skeletal muscle oxygenation during exercise improved early after TAVI. Moreover, a pre-TAVI pattern characterized by reduced oxygen delivery (lower ∆O
