Adverse events after screening and follow-up colonoscopy.
Article in Cancer causes & control : CCC, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04196088 (AIDA), which is not on this map. Cited by 47 papers, 8 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
objectiveWe provide new information about how the risk of adverse events following colonoscopy varies by age and indication (screening vs. follow-up performed to evaluate a positive result from another screening modality).
methodsWe constructed a retrospective cohort comprised of 43,456 individuals aged 40-85 years enrolled in a large integrated healthcare organization in Washington State who underwent outpatient colonoscopy between 1994 and 2009. We calculated rates of serious adverse events (perforation, hemorrhage, and acute diverticulitis) in the 30 days following colonoscopy and compared rates using log-binomial regression models.
resultsWe observed 4.7 serious adverse events per 1,000 screening colonoscopies and 6.8 per 1,000 follow-up colonoscopies. Polypectomy increased the rate of serious adverse events (relative rate [RR], 2.64; 95% confidence interval [CI], 1.97-3.56). Older age was associated with increased risk of serious adverse events, after adjusting for polypectomy, gender, and indication. Compared to individuals aged 50-64 years, risk was elevated for those aged 65-74 (RR, 1.93; 95% CI, 1.40-2.65) and 75-85 (RR, 3.21; 95% CI 2.14-4.86). We observed similar age effects in individuals with and without significant comorbid conditions.
conclusionsThe risks of serious adverse events following colonoscopy performed as part of screening are low but increase with age and are more likely after polypectomy.
