Prevalence of carotid ultrasound screening in survivors of childhood cancer: A report from the Childhood Cancer Survivor Study.

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
introductionMany childhood cancer survivors are at risk for cardiovascular disease and stroke. The North American Children's Oncology Group long-term follow-up guidelines recommend carotid ultrasound in cancer survivors 10 years after neck radiation therapy (RT) ≥40 Gy. The use of carotid ultrasound in this population has not been described.
methodsSurvivors of childhood cancer diagnosed 1970-1999 (N = 8693) and siblings (N = 1989) enrolled in the Childhood Cancer Survivor Study were asked if they had ever had a carotid ultrasound. Prevalence of carotid ultrasound was evaluated. Prevalence ratios (PR) and 95% confidence intervals (CIs) were evaluated in multivariate Poisson regression models.
resultsAmong participants with no reported cardiovascular condition, prevalence of carotid ultrasound among survivors with RT ≥40 Gy to the neck (N = 172) was 29.7% (95% CI, 22.5-36.8), significantly higher than those with <40 Gy (prevalence 10.7%; 95% CI, 9.9%-11.4%). Siblings without a cardiovascular condition (N = 1621) had the lowest prevalence of carotid ultrasound (4.7%; 95% CI, 3.6%-5.7%). In a multivariable models among survivors with no reported cardiovascular condition and RT ≥40 Gy to the neck, those who were over age 50 (vs. 18-49) at follow-up (PR = 1.82; 95% CI, 1.09-3.05), with a history of seeing a cancer specialist in the last 2 years (PR = 2.58; 95% CI, 1.53-4.33), or having a colonoscopy (PR = 2.02; 95% CI, 1.17-3.48) or echocardiogram (PR = 6.42; 95% CI, 1.54-26.85) were more likely to have had a carotid ultrasound.
conclusionMany survivors do not undergo carotid ultrasound despite meeting existing guidelines. Health care delivery features such as having seen a cancer specialist or having other testing are relevant.
