Do Common Genetic Factors Underlie Comorbidity Between Migraine and Major Depressive Disorder in Youth?

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
backgroundMigraine and major depressive disorder (MDD) are common, recurring conditions with comorbidity documented in clinical and community samples of both adults and youth. However, the etiology remains unknown. This study aims to (1) examine the prevalence and association between migraine and MDD in a large, diverse youth sample; (2) assess whether polygenic scores (PGSs) from adult genome-wide association studies are associated with these disorders in youth; and (3) evaluate shared genetic susceptibility underlying migraine-depression comorbidity.
methodsThe sample includes 8496 youth from the Philadelphia Neurodevelopmental Cohort (5239 of European-like Ancestry [EA]). Mental disorders and migraine were assessed using structured diagnostic tools aligned with Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition and International Classification of Headache Disorders. In the EA subset, PGS from adult genome-wide association studies were used to examine genetic associations.
resultsIn cross-sectional analyses, 7% of youth met migraine criteria and 12.5% met MDD criteria. Rates were similar across self-reported races. Migraine and depression were significantly associated (odds ratio = 2.05, P < 0.001). There were significant associations between the PGS for migraine and depression with those disorders in EA youth, but no cross-disorder genetic associations emerged.
conclusionsThis is the first study to examine the genetic architecture of comorbid migraine and mood disorders in a large youth sample. PGS from adults were associated with migraine and depression in youth, but the lack of cross-disorder associations suggests limited shared genetic pathways. Future studies should include prospective data to examine potential mechanisms for migraine-depression comorbidity.
