1 · What the graph read from it

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.

2 · The registry

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

objectivesTo determine the nationwide prevalence of dementia as it intersects with rurality for Aboriginal and Torres Strait Islander and non-Indigenous peoples in Australia. STUDY

designCross-sectional population-based prevalence study using nationwide respondent-reported data. SETTING,

participantsAll people aged 45 years and older, including people living in residential aged care facilities, hospitals and prisons, who responded to the 2021 Australian census.

main outcome measuresCrude, age-specific and age-standardised dementia prevalence, and odds of dementia, for Aboriginal and Torres Strait Islander and non-Indigenous peoples across remoteness levels.

resultsFor non-Indigenous peoples, the crude and age-standardised (World Health Organization standard) prevalence of dementia was 10.6 and 7.4 per 1000 persons, respectively. For Aboriginal and Torres Strait Islander peoples, the crude and age-standardised prevalence was 13.4 and 16.2 per 1000 persons, respectively. The age-specific prevalence ratio for Aboriginal and Torres Strait Islander and non-Indigenous peoples was most pronounced at younger age bands (3.5 for 45-49 years, 3.8 for 50-54 years and 3.4 for 60-64 years), narrowing to 1.6 among those aged 80-84 years. Odds of dementia decreased significantly with increasing remoteness for non-Indigenous peoples, but not for the Aboriginal and Torres Strait Islander population. Increasing age and no educational attainment were strongly associated with increased odds of dementia across both populations.

conclusionsConsideration of geography is of crucial significance in dementia epidemiology, particularly for Aboriginal and Torres Strait Islander peoples. Our findings confirm those of previous community cohort and linked data studies that highlight the disproportionate burden of dementia borne by Aboriginal and Torres Strait Islander peoples using a national dataset. Place should inform targeted health care policy to address risk and protective factors for dementia prevention and care.
