Are We Choosing Surveillance Imaging in Gastric and Pancreatic Cancers Wisely? A Population-Based Study.
Article in Journal of gastrointestinal cancer, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
BACKGROUND/
objectiveAlthough gastric and pancreatic cancers are aggressive, there is no evidence that early detection of recurrence improves overall survival. We aimed to measure the frequency of surveillance imaging in patients after curative resection for gastric and pancreatic cancers.
methodsWe performed a population-based cohort study on patients in Ontario, Canada, with a first diagnosis of gastric and pancreatic cancer in 2003-2013. Health administrative databases were linked using unique encoded identifiers to record demographics, imaging frequency, and health resource utilization.
resultsThe cohort comprised 2930 patients (2151 gastric, 779 pancreatic). The median age was 69 (38% female). The cumulative incidence of CT imaging overall was 74.3% after 1 year and 82.8% by 3 years. Imaging was more likely for pancreatic cancer compared to gastric cancer (p < 0.0001). On multivariate analysis, imaging was less likely for females and older patients and varied significantly by health district. Imaging frequency increased over the study period.
conclusionsSignificant and increasing numbers of patients received surveillance imaging after resection of gastric or pancreatic cancers despite lack of data to show its benefit. This data shows the need for the Choosing Wisely Canada recommendations (published after the study period) and serve as a baseline for future analyses.
