Effects of presentation method on the understanding of informed consent.
Trial report in The British journal of ophthalmology, 2006. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 25 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
BACKGROUND/
aimKnowledge of which presentation methods impart the most information to patients can improve the informed consent discussion. The purpose of this study was to determine if the comprehension and recall of the informed consent discussion varied with presentation method.
methodsRandomised, prospective study at the University of Arkansas for Medical Sciences. 90 freshmen medical students were randomly assigned to one of three groups and separately went through an informed consent on cataract surgery. Group A heard an informed consent presentation. Group B was shown diagrams while hearing the same presentation. Group C heard the consent and then watched an informational video on cataract surgery. A 10 point multiple choice quiz was administered after the presentation and repeated again 1 week later.
resultsScores from each group were averaged as number correct out of 10 questions. For same day scores, group C scores (7.70 (SD 1.24)) were significantly higher than group A (6.39 (1.63)). One week testing revealed that group C (6.96 (1.62)) recalled more between the two time periods and scored significantly higher than groups A (5.15 (2.11)) and B (5.54 (1.64)).
conclusionsThis study found differences in the participants' ability to recall facts based on the manner in which the material was presented. It clearly demonstrated that the use of visual aids improved the ability to remember facts and risks associated with cataract surgery beyond a verbal presentation alone. It also showed a benefit of the repetition of information as provided by audiovisual presentations that can be used in conjunction with the physician-patient discussion.
