Understanding Unwarranted Variation in Care for Victorian Oesophagogastric Cancer Patients Using Linked Data: A Comparative Analysis Between 2012-2016 and 2017-2021.
Article in ANZ journal of surgery, 2025. 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
backgroundThe Victorian Integrated Cancer Services convened the second Oesophagogastric (OG) Cancer Optimal Care Summit to determine unwarranted variation in care between 2017 and 2021 and compare trends with the first summit (reporting 2012-2016). Statewide administrative datasets were assessed retrospectively at the population level in alignment with the optimal care pathway steps for OG.
methodsVictorians with a primary diagnosis of OG cancer were identified via the Victorian Cancer Registry dataset and linked to various administrative datasets to identify unwarranted variations.
resultsOf the 9868 Victorians diagnosed with OG cancer between 2012 and 2021, 39.4% were metastatic at diagnosis. Improved outcomes between time periods included reduced mortality for OG cancer and post-surgical mortality 1 year post gastrectomy. Patient multidisciplinary meeting presentation increased from 74% to 86%. Unwarranted variations included time from diagnosis to any treatment within 6 weeks for non-metastatic gastric cancer (64%, 2012-2016 and 60%, 2017-2021) and for oesophageal cancer patients (58%, 2012-2016 and 60%, 2017-2021). One regional Integrated Cancer Service (ICS) demonstrated statistically lower survival compared to the statewide average for gastric cancer in 2017-2021. There was greater variation in survival for gastric cancer for 2017-2021 compared to 2012-2016. Rates of dietitian and/or physiotherapist involvement within 3 months of diagnosis for OG cancer surgical and/or chemotherapy patients were low across all ICS and both time periods.
conclusionsThe Victorian cancer system demonstrates improved survival outcomes for OG cancer patients between the two time periods. Time between diagnosis and treatment, lower survival rates in some ICS, and access to supportive care (e.g., dietetics and physiotherapy) remain areas of deficiency.
