Impact of postdischarge care fragmentation on clinical outcomes and survival following transcatheter aortic valve replacement.
Article in Herz, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundThe study aimed to evaluate the prognostic impact of postdischarge care fragmentation in patients undergoing transcatheter aortic valve replacement (TAVR).
methodsA total of 266 patients undergoing TAVR due to severe aortic stenosis were included in this retrospective cohort study. Patients were assigned to one of two groups based on presence (n = 104) and absence (n = 162) of postdischarge care fragmentation. Fragmented care was defined as at least one readmission to a site other than the implanting TAVR center within 90 days. Prognostic impact of care fragmentation on clinical outcomes and predictors of long-term mortality were investigated.
resultsIncreased major vascular complication (16.3 vs 8.0%, p = 0.037), permanent pacemaker implantation (14.4 vs 6.2%, p = 0.025), and acute kidney injury (22.1 vs 14.2%, p < 0.001) were reported in the fragmented care group. Although early mortality (6.7 vs 4.3%, p = 0.152) was similar between groups, there was a significant difference in 5‑year mortality (66.3 vs 45.7%, p < 0.001). In a univariate regression analysis fragmented care, age, chronic obstructive pulmonary disease, pulmonary artery systolic pressure, and paravalvular leakage were significantly associated with 5‑year mortality. Fragmented care (hazard ratio [HR] 1.510, 95% confidence interval [CI] 1.080-2.111; p = 0.016), age (HR 1.024, 95% CI 1.001-1.048; p = 0.045), paravalvular leakage (HR 1.863, 95% CI 1.076-3.228; p = 0.026), and chronic obstructive pulmonary disease (HR 1.616, 95% CI 1.114-2.344; p = 0.012) were found to be significant independent predictors of 5‑year mortality in a multivariate analysis, after adjusting for other risks.
conclusionFragmented care has a significant prognostic impact on clinical outcomes and survival.
