Abstract
BACKGROUND: There is increasing interest in direct oral anticoagulants (DOACs), given their safety and convenience in atrial fibrillation, compared with vitamin K antagonists (VKAs). However, the use of DOACs in left ventricular (LV) thrombi is considered off-label, with current guidelines recommending VKAs. The aim of this meta-analysis was to compare the safety and efficacy of DOACs to VKAs in the management of LV thrombi. METHODS: A systematic search was conducted for studies published between January 1, 2009 and January 31, 2021 in PubMed, Embase, and CENTRAL. Included studies compared DOACs to VKAs for the treatment of LV thrombi and reported on relevant outcomes. Odds ratios (ORs) were pooled with a random-effects model. RESULTS: = 56%). CONCLUSIONS: Within the context of low-quality evidence, there was a statistically significant reduction in stroke among those treated with DOACs, without an increase in bleeding. There were no significant differences in systemic embolism, stroke or systemic embolism, mortality, or LV thrombus resolution, suggesting that DOACs may be a reasonable option for treatment of LV thrombi.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
