Sensitivity analyses without adjustment for stroke severity also supported that insomnia was causally associated with poor functional outcome (OR = 1.25; 95% CI: 1.08–1.44, p = 0.003). In the multivariable MR analysis adjusting for potentially confounding traits including body mass index, depression, type 2 diabetes, smoking, and alcohol consumption, the overall patterns between genetic liability to insomnia and poststroke outcome remained (all p < 0.05).Discussion This MR study supports potential adverse effects of liability to insomnia on functional outcome after ischemic stroke. Interventions that address insomnia may offer a therapeutic target to improve recovery after ischemic stroke and warrant exploration in a clinical context.BMI=body mass index; GISCOME=Genetics of Ischemic Stroke Functional Outcome; IVW=inverse-variance weighted; MR=Mendelian randomization; mRS=modified Rankin Scale; NIHSS=NIH Stroke Scale; OR=odds ratio; SNPs=single nucleotide polymorphisms; T2D=type 2 diabetes; UKB=UK Biobank
