For grip strength, several marginally significant proteins (ERBB1, adapter molecule crk, teratocarcinoma‐derived growth factor 1, complement C1r subcomponent, glutathione S‐transferase P) were no longer significant after excluding stroke participants and C‐X‐C motif chemokine 9 and Beta‐2‐microglobulin reached the statistical significance threshold (Table S7). The gene discussed is C1R; the disease is Stroke.
