Ezetimibe enhances and stabilizes anticoagulant effect of warfarin.
Article in Heart and vessels, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. 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
Ezetimibe reduces plasma levels of low-density lipoprotein cholesterol by inhibiting Niemann-Pick C1-like protein 1 (NPC1L1). A recent study demonstrated that NPC1L1 plays an important role in absorption of fat-soluble vitamins including vitamin K. We evaluated whether the add-on treatment of ezetimibe affects anticoagulation in patients taking warfarin. Between October 2007 and March 2015, the administration of ezetimibe was started to a total of 101 outpatients who were already on oral anticoagulation with warfarin. We retrospectively analyzed blood lipid levels, prothrombin time international normalized ratio (PT-INR) and time in therapeutic INR range (TTR). Seventy-one patients (70 %) showed increase in PT-INR after ezetimibe treatment (1.96 ± 0.45 to 2.20 ± 0.61, p < 0.001). It was necessary to reduce the warfarin dose in 9 of 101 patients for clinical indication. There was a significant positive correlation between change in PT-INR and statin usage at baseline (p = 0.03). The mean value of changes in PT-INR of patients with taking statin was significantly larger than that of patients without taking statin (0.34 ± 0.54 vs. 0.06 ± 0.36, p = 0.03). There was an increase in the TTR (52 ± 26 to 61 ± 23 %, p < 0.0001) and a decrease in the frequency to change the dose of warfarin after the ezetimibe treatment [45 times of 735 examination days (6 %) to 20 times of 695 examination days (3 %), p = 0.02]. Our data suggest possible drug interaction between warfarin and ezetimibe. Ezetimibe may increase and stabilize the anticoagulant effect of warfarin, especially in patients taking statins.
