Severity of and Recovery From Anemia After Transcatheter Aortic Valve Replacement: An Analysis of the PARTNER Trials and Registries.
Article in Journal of the Society for Cardiovascular Angiography & Interventions. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 3 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: Anemia is associated with increased mortality in patients undergoing transcatheter aortic valve replacement (TAVR); however, data on the effect of the severity of and recovery from anemia on clinical outcomes are limited. This study examined the impact of the severity of and recovery from anemia after TAVR. Methods: Patients with symptomatic, severe aortic stenosis across all surgical risk groups from the Placement of Aortic Transcatheter Valves (PARTNER) I, II, and III trials and registries who underwent TAVR were analyzed. Baseline anemia was defined as mild (hemoglobin [Hb] level ≥11.0 g/dL and <13.0 g/dL for men and ≥11.0 g/dL and <12.0 g/dL for women) and moderate-to-severe anemia (Hb level <11.0 g/dL). Recovery from anemia was defined as an increase of ≥1 g/dL in the Hb level. Patients with missing Hb information and major bleeding within 30 days were excluded. The association of the severity of and recovery from anemia with clinical outcomes was analyzed using multivariable Cox proportional hazards regression models. The primary outcome was 1-year all-cause mortality. Results: The Kaplan-Meier estimate for 1-year all-cause mortality was 5.4%, 8.2%, and 14.5% in patients with no, mild, and moderate-to-severe anemia, respectively ( Conclusions: In patients undergoing TAVR, moderate-to-severe anemia is independently associated with increased 1-year mortality, and recovery from anemia after TAVR is associated with favorable outcomes. Further efforts are needed to determine whether preprocedural correction of anemia improves post-TAVR outcomes.
