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
objectiveThe study was to assess the knowledge of warfarin in patients using the validated anticoagulation knowledge assessment questionnaire and to evaluate the predictors of the level of knowledge among outpatients receiving warfarin at the Tikur Anbessa Specialized Hospital, Addis Ababa, Ethiopia.
methodsIt was a prospective cross-sectional study carried out from October 2019-January 2020. During the study period a total 401 of them were included in the study. Anticoagulation Knowledge Assessment questionnaire has 29 question items, a single patient should answer at least 21 of the question to be considered as knowledgeable about his/her medication. The data was exported into SPSS version 25 and a one way ANOVA and post hoc were conducted.
resultsThe mean age of the study participants were 36 years old (SD ± 11.83), which was ranges from 18 to 82 and majority of the participants were females (69.6%). Almost in one-third of the participants (35.7%), the reasons for warfarin therapy were Chronic Rheumatic Valvular Heart Disease. The overall AKA mean ± SD score of the respondents was 7.4 (±2.6) that ranges from 2 to 22. From those only (4.2%) of the study participants had succeeds the passing score. Educational level and the duration of warfarin therapy were independent predictors towards patient's warfarin knowledge.
conclusionThe overall patient's knowledge about warfarin treatment was poor when it was compared to most other studies. The longer duration of warfarin therapy and advanced educational level showed favored relationship towards better warfarin knowledge of the study participants.
