Prevalence of Dementia in European, Chinese and Indian/Fijian-Indian Populations in Aotearoa New Zealand: A Protocol.
Article in International journal of geriatric psychiatry, 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
objectivesAotearoa New Zealand (NZ) is a bicultural nation (Māori and European) with a growing population of Asian and Pacific peoples. Recent analysis of national routinely collected data suggests dementia prevalence is higher in Māori and Pacific peoples when compared with European and Asian, and that inequities in dementia care for Māori, Asian, and Pacific people with dementia exist. A population-based dementia prevalence study is needed to confirm these findings. The aim of this protocol is to describe a dementia prevalence study focussing on the European, Chinese and Indian populations in NZ. The findings will be compared to a separate study on Māori populations using a similar study design.
methodsThis is a cross-sectional screen-interview survey of people aged ≥ 65 from European, Chinese and Indian/Fijian-Indian backgrounds in sampled meshblocks within two regions of NZ. Stage 1 involves screening eligible participants at the door using the brief cognitive scale of the Community Screening Instrument for Dementia (CSI-D). Stage 2 involves interviewing random samples of screen positive and negative participants using the 10/66 dementia protocol. With a margin of error of approximately 3%, and a confidence level of 5%, a total of 485 European, 410 Chinese and 425 Indian/Fijian-Indian people will be interviewed with the 10/66 protocol. Age-standardised prevalence estimates of 10/66 dementia will be back-weighted for study design.
conclusionThis study will provide evidence for suspected ethnic inequalities in dementia, inform new culturally appropriate dementia management strategies, and contribute to improved outcomes for people with dementia in NZ.
