What's Needed for a Migraine Cost-Of-Illness Study in Aotearoa New Zealand: Review of Data Sources and Gaps.
Review in Journal of the Royal Society of New Zealand, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Cost of illness (COI) studies are used to quantify the economic burden of disease on health systems, employers and society, and identify where costs may be saved by improvements in disease management. Many migraine COI studies have been published internationally but none have included data from Aotearoa New Zealand (NZ), despite the known high prevalence and individual health burden of migraine. Adapting methods for data reviews developed at the University of Auckland, we reviewed known data sources to identify relevant NZ datasets containing information on migraine prevalence, direct and indirect costs from migraine, supplemented by searches of peer-reviewed literature. Data sources were evaluated against pre-defined criteria to assess quality. We found adequate data on migraine prevalence but limited to no data on migraine-specific indirect costs (absenteeism or presenteeism, reduced employment or inability to work because of migraine). Data on direct costs were insufficient, due to poor or lack of diagnostic data in key areas such as primary care, pharmaceuticals, outpatients, laboratory or imaging tests. This review revealed significant data gaps that would need to be filled for a comprehensive and robust NZ migraine COI study or any ongoing research into migraine in NZ.
