Assessment of the quality of anticoagulation management with warfarin in a tertiary care center.
Article in Saudi medical journal, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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
objectivesTo evaluate the quality of an anticoagulation clinic in a tertiary hospital and identified factors affecting the time in the therapeutic range (TTR) and its relation to different complications. Methods: This single-center retrospective study conducted between March 2015 and June 2016 included 1914 patients receiving warfarin therapy. They were divided into 4 warfarin indication groups: non-valvular atrial fibrillation (AF) (n=403), valvular AF (n=227), prosthetic valves (n=700), and venous or pulmonary embolism (n=584).
resultsThe median age was 56 (25th, 75th percentiles: [45, 67]) years, and 53.2% were female. The median TTR was 0.52 (0.28, 0.76). Low hemoglobin (0.007) and high alkaline phosphatase (0.020) levels negatively affected the TTR. Venous thromboembolism (VTE) was associated with low TTRs. Minor bleeding occurred in 64 (3.35%), gastrointestinal bleeding in 14 (0.7%), and stroke in 41 (2.2%) patients, with no inter-group differences. The TTR was not associated with minor bleeding (odds ratio [OR]=0.49; p=0.09), gastrointestinal bleeding (OR=0.29; p=0.18), or stroke (OR=1.15; p=0.79).
conclusionReflecting the real-life experience of anticoagulation control, our patients spend less than half the TTR within the INR. The low target TTR mandates the need to improve service quality and control factors affecting the TTR, including hemoglobin levels and regular visits for patients with VTE.
