Educational Video Addition to the Bariatric Surgery Informed Consent Process: a Randomized Controlled Trial.
Trial report in Obesity surgery, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
objectiveBariatric surgery is not a risk-free procedure and requires lifelong patient compliance in the postoperative period. Although the risks involved in bariatric surgery and the importance of lifelong follow-ups in the postoperative period are explained to patients in detail through verbal and written informed consent, the strong desire for weight loss can sometimes cause patients and their families to be ignorant of the mentioned issues preoperatively. The objective of this study is to evaluate the effectiveness of preoperative informational videos at improving the comprehension of informed consent content in bariatric surgery candidates. MATERIALS AND
methodsA total of 74 bariatric surgery candidates were randomized into two groups. The first group was given a usual verbal-written informed consent. The second group got an additional informing video presentation informed consent, in addition to the usual verbal-written informed consent. Then, both groups got a questionnaire evaluating their knowledge of bariatric surgery informed consent. The correct response scores and their relationship with patient demographics were analyzed.
resultsBoth groups had similar demographic features. Video-presented group had higher scores in questionnaire (11.3 ± 2.3 versus 9.4 ± 1.7, p = 0.001). Subgroup analysis showed that health care workers (12.5 ± 1.9 versus 10.3 ± 2.2, p = 0.005) and university graduates (11.6 ± 2.4 versus 10.1 ± 2.1, p = 0.03) got better results in the questionnaire. In multivariate analysis, video-assisted informing was found to be the only independent variable for high questionnaire scores (p = 0.0001).
conclusionsThis study showed that video-assisted informed consent improves patients' comprehension prior to bariatric surgery. We recommend routine preoperative video-assisted informing for bariatric surgery candidates in addition to usual verbal-written informed consent.
