The economic burden of pain in migraine: a national study of U.S. healthcare expenditures.
Article in Frontiers in neurology. 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
Background: Migraine is a prevalent and disabling neurological disorder associated with substantial healthcare costs. Coexisting pain is frequently reported among individuals with migraine and may significantly exacerbate both clinical burden and healthcare expenditures. However, limited research has quantified the specific contribution of pain to excess healthcare costs in this population. Methods: We conducted a cross-sectional analysis using 2019-2022 data from the Medical Expenditure Panel Survey (MEPS) to examine the impact of pain on healthcare expenditures among U.S. adults with migraine. Pain was identified using a self-reported measure of pain interference with daily activities. Individuals were categorized into two groups: migraine with pain and migraine only (without pain). Generalized linear models (GLMs) were used to estimate adjusted healthcare costs, and Blinder-Oaxaca decomposition was applied to assess the extent to which observed cost differences were attributable to patient characteristics. Results: Among 1,411 adults with migraine, 66% reported pain that interfered with daily function. Individuals with migraine and pain incurred significantly higher total healthcare expenditures than those without pain ($18,748 vs. $10,042; Conclusion: Pain substantially increases the economic burden of migraine, largely through elevated outpatient care costs. These findings highlight the need for comprehensive pain assessment and integrated care strategies to manage pain in individuals with migraine and reduce healthcare expenditures.
