The Impact of a Pharmacist-led Warfarin Educational Video in a Saudi Setting.

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
contextInternationally, various warfarin education strategies have been described in the medical literature and delivered by a variety of health-care providers. However, none of these were tested in a Saudi setting.
aimThe aim of this study was to assess the impact of pharmacist interventions via an educational video on improving patient knowledge of and satisfaction with warfarin therapy and the international normalized ratio (INR). SETTING AND
designThis study adopted a prospective pre- and posttest design and enrolled 91 patients from an anticoagulant clinic at King Khaled University Hospital in Riyadh, Saudi Arabia, between September 2017 and February 2018. MATERIALS AND
methodsAll patients completed the Anticoagulation Knowledge Assessment (AKA) and Anti-Clot Treatment Satisfaction (ACTS) scales. Subsequently, the patients watched a 10-min educational video containing basic information regarding warfarin and were given relevant informative booklets. The patients were reassessed after a mean follow-up period of approximately 52 days.
resultsIn total, 85 patients completed the study. The impact of the intervention on patient knowledge was highly significant (mean difference = 17.7%, 95% confidence interval (CI) = 21.75-13.58,
conclusionThis study provided evidence that a pharmacist-led audiovisual intervention via an educational video coupled with an informational booklet effectively improved patients' knowledge retention and satisfaction with warfarin therapy benefits. Longer studies are needed to determine the impact of this intervention on patients' perceptions of warfarin burdens and their INRs.
