Counts, Characteristics and Outcomes of Patients Transported by the Royal Flying Doctor Service to Metropolitan Perth With Suspected Acute Coronary Syndrome: Western Australian Linked Data Study.
Article in The Australian journal of rural health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectivesDetermine counts, characteristics and outcomes following transport by the Royal Flying Doctor Service Western Operations (RFDSWO) to Perth. STUDY
designRetrospective cohort study of the RFDSWO aeromedical patient dataset linked to administrative datasets.
participantsSuspected acute coronary syndrome (ACS) patients aged ≥ 25 years transported from rural Western Australia to Perth between 2001 and 2017.
main outcome measuresBasic counts and proportions. Poisson regression was used to determine absolute change in number of transports and relative risk (RR) of receiving diagnostic coronary angiography; logistic regression to model odds ratio (OR) of death between transport and end of hospital care.
resultsRFDSWO carried out 11 390 transports for suspected ACS between 2001 and 2017, with the absolute number of annual transports increasing by 6.0%. After excluding 164 transports without linked records, the remaining 11 226 consisted of patients with a mean age of 60.3 years and 70.8% male. Most (99.1%) were hospitalised and 1.8% died. Among those hospitalised, 84.5% received diagnostic coronary angiography and 74.5% were discharged with a diagnosis of ACS. Females (RR = 0.97; CI = 0.95-0.99), higher comorbidity scores, and those from the Pilbara/Midwest/Wheatbelt regions (compared to South West) were less likely to receive diagnostic coronary angiography. Older patients (OR = 1.07; CI = 1.06-1.11), earlier transport years, higher comorbidity scores, those with priority 1 transport or requiring medical escort, and those from the Kimberley (compared to South West) were more likely to die.
conclusionsFindings suggest a high suspicion of coronary artery pathology among transported patients. Patient-level and regional differences in outcomes warrant further investigation with more granular data.
