Resolution of left atrial appendage thrombi: No difference between phenprocoumon and non-vitamin K-dependent oral antagonists.
Observational study in Clinical cardiology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundAtrial fibrillation is the most important risk factor for left atrial appendage (LAA) thrombi, a potentially life-threatening condition. Thrombus resolution may prevent embolic events and allow rhythm-control strategies, which have been shown to reduce cardiovascular complications. HYPOTHESIS: There is no significant difference between phenprocoumon and non-Vitamin K-dependent oral anticoagulants (NOACs) in the resolution of LAA-thrombi in a real-world setting.
methodsConsecutive patients with LAA-thrombi from June 2013 to June 2017 were included in an observational single-center analysis. The primary endpoint was defined as the resolution of the thrombus. The observational period was 1 year. Resolutions rates in patients on phenprocoumon or NOACs were compared and the time to resolution was analyzed.
resultsWe identified 114 patients with LAA-thrombi. There was no significant difference in the efficacy of resolution between phenprocoumon and NOACs (p = .499) at the time of first control which took place after a mean of 58 ± 42.2 (median 48) days. At first control most thrombi were dissolved (74.6%). The analysis after set-time intervals revealed a resolution rate of 2/3 of LAA-thrombi after 8-10 weeks in the phenprocoumon and NOAC groups. After 12 weeks a higher number of thrombi had resolved in the presence of NOAC (89.3%) whereas in the presence of phenprocoumon 68.3% had resolved (p = .046).
conclusionIn this large observational study NOACs were found to be potent drugs for the resolution of LAA-thrombi. In addition, the resolution of LAA-thrombi was found to be faster in the presence of NOAC as compared to phenprocoumon.
