Multiple linear regression analysis of the atrial cell L-type Ca²⁺ current, I_CaL. Post-CS period studied=3 days. I_CaL estimate=estimated difference in mean I_CaL between highest (eg: drug-treatment) and lowest (eg: non-drug-treatment) level of variable, or male minus female. Values are subject (patient) means±standard error (SE). Number of patients with post-CS AF=18/103.
