An Interactive Video Educational Tool Does Not Improve the Quality of Bowel Preparation for Colonoscopy: A Randomized Controlled Study.
Trial report in Digestive diseases and sciences, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT07229066 (Evaluation of the Effect of Video-Based Education on Bowel Preparation Before Colonoscopy), which is not on this map. Cited by 11 papers, 3 of them syntheses 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.

Abstract
BACKGROUND/
aimsInadequate bowel preparation leads to poor outcomes in colonoscopy. Prior investigations have demonstrated improved bowel preparation with pre-procedural educational videos. We aimed to determine whether an interactive, online educational video could improve bowel preparation scores in an outpatient population.
methodsWe performed a prospective, endoscopist-blinded, randomized controlled trial at our hospital-based outpatient endoscopy center. Eligible patients were randomized to two groups. Both groups received standard verbal and written instructions, while the intervention group also received access to an interactive, online video. The primary outcome was improvement in the bowel preparation scores graded using the Boston bowel prep score (BBPS). Secondary outcomes included adenoma detection rate, total number of polyps detected, patient satisfaction, pre-procedure anxiety, and complication rates.
resultsThe difference in BBPS in the intervention group (8) compared to the control group (7.6) did not meet statistical significance in our primary outcome of improvement in BBPS (p = 0.076). However, on subgroup analysis, there was a statistically significant improvement in BBPS in the intervention group among African Americans (p = 0.007) and patients older than 65 (p = 0.026). Those in the intervention arm rated pre-procedural materials "very easy" to understand significantly more often than in the control arm (p = 0.018).
conclusionsUse of an interactive, online educational video for bowel preparation did not lead to improvement in overall BBPS. However, among patients at higher risk for inadequate bowel preparation, such as African Americans and elderly patients, there may be a benefit.
