Small Left Ventricle and Clinical Outcomes After Transcatheter Aortic Valve Replacement.
Article in Journal of the American Heart Association, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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.
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 In patients undergoing transcatheter aortic valve replacement (TAVR), those with small left ventricle (LV) may have an increased risk of poor outcomes, because small LV is associated with low-flow (LF), left ventricular hypertrophy. However, the impact of small LV on patients undergoing TAVR remains unknown. Methods and Results We examined 2584 patients who underwent TAVR between October 2013 and May 2017 using data from the Japanese multicenter registry. On the basis of the American Society of Echocardiography guidelines, small LV was defined as left ventricular end-diastolic dimension <42.0 mm for men or <37.8 mm for women. The 2-year clinical outcomes were compared between patients with and without small LV using multivariable Cox regression analyses and propensity score matching. Subgroup analyses by LF, left ventricular hypertrophy were performed. Of 2584 patients who underwent TAVR, 466 (18.0%) had small LV. Patients with small LV had smaller body size and less comorbidity, and were more likely to have LF status compared with those without. Small LV was associated with a higher 2-year all-cause (20.8% versus 14.3%; adjusted hazard ratio [HR],1.58 [95% CI, 1.20-2.09];
