Factors associated with polyp detection during colonoscopy: A retrospective observational study.
Observational study in The Kaohsiung journal of medical sciences, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
The polyp detection rate (PDR) is an important quality indicator for colonoscopy. Several factors have been shown to be associated with PDR. However, whether the moderate sedation is a factor for polyp detection remains controversial. This study aims to assess factors associated with polyp detection including the moderate sedation factor during colonoscopy. Patients who underwent colonoscopy from June 1, 2014 to May 31, 2015 were enrolled into this retrospective study. Patients with poor colon preparation and failure to reach the cecum were excluded. The clinical factors, including patient's sex, age, midazolam/fentanyl sedation, indications, endoscopist colonoscopy volume, and use of antispasmodic agent were evaluated by multivariate analysis. A total of 3373 patients were included in this study. The mean age was 55.8 years, and 1980 patients (58.7%) were male. Among the 3373 patients, 2513 (74.5%) underwent midazolam/fentanyl-based sedated colonoscopy. The multivariate analysis showed that male sex, age over 50 years old, midazolam/fentanyl sedation and indications of screening and surveillance were significantly associated with polyp detection. Moreover, when stratified by sex and age, the midazolam/fentanyl sedation was associated with polyp detection in male patients and patients over 50 years old. This study has highlighted the role of midazolam/fentanyl sedation administered by colonoscopists as a modifiable factor that may increase polyp detection during colonoscopy.
