Central blood pressure profile variability and prognostic impact of transcatheter aortic valve implantation.

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
Transcatheter aortic valve implantation (TAVI) is a proven treatment for severe aortic stenosis (AS); however, the effects of TAVI on central blood pressure (CBP) and clinical outcomes remain unclear. We assessed CBP indices before and after TAVI and their prognostic value. Seventy-six patients with severe AS who underwent TAVI were retrospectively evaluated, and CBP was estimated noninvasively 1 day before and after TAVI. The following indices were measured: augmentation index corrected for heart rate (HR) (AIx@HR75), peak pressure of the forward wave (Pf) and backward wave (Pb), time to peak pressure of the forward wave corrected for HR (Tfc) and the backward wave corrected for HR (Tbc), and ejection duration (ED). The primary endpoint was the composite outcome of all-cause mortality and hospitalized heart failure. The median follow-up period was 1135 (844-1404) days. Tfc, Tbc, ED, Pb, and AIx@HR75 decreased despite no significant changes in Pf after TAVI. The univariable Cox proportional hazards model showed that ED 1 day after TAVI was associated with composite outcomes (hazard ratio: 1.02; 95% confidence interval [CI]: 1.01-1.04; P = 0.002). When the patients were divided into two groups by the cutoff value determining composite outcomes by receiver operating characteristic curve analysis, a long ED 1 day after TAVI was significantly associated with composite outcomes by Kaplan-Meier curve analysis (log-rank test, P < 0.001). The multivariable Cox proportional hazards model showed that a long ED 1 day after TAVI was associated with composite outcomes (adjusted hazard ratio: 12.12; 95% CI 2.41-60.81; P = 0.002). In conclusion, a long ED 1 day after TAVI was associated with adverse clinical outcomes.
