Apixaban for the treatment of cancer-associated venous thromboembolism and left atrial appendage thrombus refractory to optimal anticoagulation with warfarin: a case report.
Article in European heart journal. Case reports, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
backgroundConcomitant venous thromboembolism (VTE) and left atrial appendage (LAA) thrombus associated with cancer is exceedingly rare. The use of direct factor Xa inhibitors in patients with cancer is controversial. CASE SUMMARY: We report a rare case of concomitant VTE and LAA thrombus in an 85-year-old man with prostate cancer. He developed VTE and LAA thrombus, while on warfarin therapy for non-valvular atrial fibrillation. Despite optimal medical treatment with warfarin, systemic thrombosis developed. After thrombolysis, he was prescribed apixaban, an oral direct factor Xa inhibitor, as maintenance therapy. Deep venous thrombosis, pulmonary embolism, and LAA thrombus were effectively treated, and his symptoms resolved. DISCUSSION: Despite the fact that many patients with cancer are in a hypercoagulable state, to the best of our knowledge, this is a first case describing VTE and LAA thrombus presenting concomitantly during optimal warfarin therapy. This case demonstrates the importance of awareness of systemic thrombosis in patients with cancer regardless of vitamin K antagonist therapy. More cases and larger scale data are needed to investigate if factor Xa inhibitors are useful for treating systemic thrombosis in patients with cancer.
