Right Or Left in COLonoscopy (ROLCOL)? A Randomized Controlled Trial of Right- versus Left-Sided Starting Position in Colonoscopy.
Trial report in The American journal of gastroenterology, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to 3 registered trials, which are not on this map. Cited by 22 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.

Abstract
objectivesColonoscopy is technically challenging and can cause discomfort for patients. We aimed to test whether right-sided starting position for colonoscopy would result in shorter procedure time and greater patient comfort when compared with conventional left-sided starting position.
methodsWe conducted a randomized controlled trial in which patients were randomized to begin in either the right- (RL) or conventional left-lateral (LL) position. One hundred and sixty-three adult patients undergoing scheduled colonoscopy were stratified by age, gender, body mass index, and experience of the endoscopist. Patients were then randomized 1:1 in permuted blocks. The primary outcome measure was time to cecal intubation and secondary outcome measures included patient comfort that was evaluated by visual analog comfort scale.
resultsMedian time to reach the cecum was quicker when colonoscopy began with patients positioned RL rather than LL (P=0.0078). Moreover, patients found RL more comfortable than LL (P=0.02). Multiple linear regression confirmed starting position in colonoscopy as an independent determinant of time to reach the cecum (P=0.007). Women and those who had previously undergone abdominal surgery gained the greatest benefit from right-sided positioning (RL vs. LL: 498 vs. 824 s; P=0.03 and 498 vs. 797 s; P=0.006, respectively).
conclusionsOur study reveals that right-sided positioning at the start of colonoscopy results in more comfortable and quicker procedures. Of the factors identified by multiple linear regression to independently have an impact on time to reach the cecum, only starting position is modifiable. Right-sided starting position may therefore be of benefit in colonoscopy, in particular for women and patients who have previously undergone abdominal surgery.
