A Centralized Program with Stepped Support Increases Adherence to Colorectal Cancer Screening Over 9 Years: a Randomized Trial.
Trial report in Journal of general internal medicine, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT00697047 (Systems of Support to Increase Colon Cancer Screening and Follow-up), which is not on this map. Cited by 5 papers.
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
backgroundScreening over many years is required to optimize colorectal cancer (CRC) outcomes.
objectiveTo evaluate the effect of a CRC screening intervention on adherence to CRC screening over 9 years.
designRandomized trial.
settingIntegrated health care system in Washington state.
participantsBetween August 2008 and November 2009, 4653 adults in a Washington state integrated health care system aged 50-74 due for CRC screening were randomized to usual care (UC; N =1163) or UC plus study interventions (interventions: N = 3490).
interventionsYears 1 and 2: (arm 1) UC or this plus study interventions; (arm 2) mailed fecal tests or information on scheduling colonoscopy; (arm 3) mailings plus brief telephone assistance; or (arm 4) mailings and assistance plus nurse navigation. In year 3, stepped-intensity participants (arms 2, 3, and 4 combined) still eligible for screening were randomized to either stopped or continued interventions in years 3 and 5-9. MAIN MEASURES: Time in adherence to CRC testing over 9 years (covered time, primary outcome), and percent with no CRC testing in participants assigned to any intervention compared to UC only. Poisson regression models estimated incidence rate ratios for covered time, adjusting for patient characteristics and accounting for variable follow-up time. KEY
resultsCompared to UC, intervention participants had 21% more covered time over 9 years (57.5% vs. 69.1%; adjusted incidence rate ratio 1.21, 95% confidence interval 1.16-1.25, P<0.001). Fecal testing accounted for almost all additional covered time among intervention patients. Compared to UC, intervention participants were also more likely to have completed at least one CRC screening test over 9 years or until censorship (88.6% vs. 80.6%, P<0.001).
conclusionsAn outreach program that included mailed fecal tests and phone follow-up led to increased adherence to CRC testing and fewer age-eligible individuals without any CRC testing over 9 years.
