An Assessment of Radiotherapy and Surgery Utilisation and Health Outcomes, in Aboriginal and Non-Aboriginal People With Cancer in NSW, Australia, 2009-2018.

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
introductionAboriginal patients face barriers to accessing cancer care. Few studies have evaluated the utilisation of radiotherapy or surgery in Aboriginal people. This study aims at assessing variation in types of cancer, degree of spread (DOS) at presentation, utilisation rates of cancer surgery and radiotherapy between Aboriginal and non-Aboriginal cancer patients.
methodsRetrospective analysis of de-identified linked datasets. All patients with registered notifiable cancer in the NSW cancer registry 2009-2018 separated by Aboriginality status were included.
resultsTotally 389,992 people were diagnosed in NSW during study period; 8970 people (2.3%) identified as Aboriginal. In univariate analysis, Aboriginal people presented at diagnosis with statistically significant younger age, greater comorbidity, advanced (DOS) and greater proportions living in most disadvantaged areas than non-Aboriginal people. Based on univariate analysis, Aboriginal patients received radiotherapy more frequently than non-Aboriginal patients (30.3% versus 26.0%, p < 0.01). Non-Aboriginal patients underwent cancer surgery more frequently than Aboriginal patients (57.0% versus 51.2%, p < 0.01). When stratified by tumour type and adjustment for patient and clinical factors, radiotherapy and surgery utilisation varied by type of cancer.
conclusionsThe degree of cancer spread, and the presence of comorbidities remains a greater issue for Aboriginal people. Access to radiotherapy increased significantly for Aboriginal patients during the past 10 years. However, differences in surgical and radiotherapy utilisation exist. These differences can be partially explained by the greater DOS and presence of comorbidity in Aboriginal patients leading to less surgical intervention and greater requirement for radiotherapy.
