Review in Current treatment options in gastroenterology, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03571061 (Comparisons of Sigmoid-colon Water Immersion, the Whole Colon Water Immersion and Carbon Dioxide), which is not on this map.

1 · What the graph read from 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

opinion statementThe current review will attempt to describe the important lessons learned from published randomized controlled trials (RCT) comparing water immersion (WI) or water exchange (WE) techniques with gas insufflation colonoscopy. Air insufflation (AI) to distend the colon to permit visualization and passage through the lumen was developed for diagnostic colonoscopy. When screening colonoscopy was adopted, the same AI method was used. Interval cancers, diagnosed within 3 to 5 years after an index screening colonoscopy, appeared to be linked to low adenoma detection rate (ADR). Conscious sedation was introduced to manage insertion pain a few decades ago, incurring moderate costs of nursing staff, space for recovery, patient burdens of escort requirement, and at home recovery time. Recent advancement to deep sedation entailed additional costs of anesthesia staff support. In the past decade, investigators worldwide evaluated the use of water-assisted methods as an adjunct or in lieu of gas insufflation during insertion to minimize discomfort and improve ease of insertion. For convenience, one approach embraced the removal of infused water during withdrawal (WI). A subsequent evolution entailed removal of infused water predominantly during insertion (WE), specifically designed to further minimize insertion pain. Results of RCT shed light on the impact of WI and WE on insertion pain (primary outcome) and adenoma detection (secondary outcome). Water immersion is easier to learn and apply than WE, but mastery of the WE technique appears to have two major advantages. Current RCT data suggest that both WI and WE decrease insertion pain and facilitate completion of difficult colonoscopy, with WE having a superior impact than WI. Water exchange was serendipitously associated with an increase in ADR; this has been repeatedly confirmed in follow-up studies. When it is unknown which patient's colonoscopy will be difficult, it would seem prudent for the average colonoscopist to optimize the chance of success and increase in ADR by using WE from the very start.
