The effect of multimedia interventions on the informed consent process for cataract surgery in rural South India.
Trial report in Indian journal of ophthalmology, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
contextThe provision of ocular surgical interventions for poorer, less educated populations is increasing as a result of increased globalization and outreach. However, these populations still have trouble understanding surgical concepts and are not always fully informed decision makers.
aimsWe aimed to test the effect that a multimedia addition to a traditional verbal informed consent would have on patient comprehension of relatively difficult cataract surgical concepts. SETTINGS AND
designWe conducted a randomized controlled trial with relatively uneducated patients reporting to a private surgical hospital in Chennai, India. 47 patients were placed into the intervention group and 50 patients were placed into the control group. MATERIALS AND
methodsThe intervention group was presented with a scripted verbal informed consent as well as a 3-fold pamphlet and a presentation with a 3-dimensional model of the eye. The control group was only presented with a scripted verbal informed consent. The two groups were tested using an 11 item "True/False/I don't know" quiz directly before the informed consent, directly after the informed consent, and one-day postoperatively. STATISTICAL ANALYSIS USED: Scores on the quiz were compared across groups and time-points using paired t-tests.
resultsPatients in the both groups showed a significant improvement in scores between pre- and post-informed consent quizzes (P value on the order of 10(-6)) and the improvement in scores was significantly greater in the intervention group than the control group (P value on the order of 10(-16)). There was no significant difference observed in either group with regards to the change in scores between post-informed consent and post-operative quizzes.
conclusionMultimedia aids in addition to a standard informed consent process are effective in improving patient comprehension even for patients with low literacy and limited knowledge of surgical interventions.
