A significant trend (P = 0.001) across eGFRcys categories was found, with an HR of 2.11 (95% CI 1.19–3.74) for eGFRcys <60 compared with eGFRcys >90 mL/min/1.73 m 2 .

There seemed to be a differential risk of SCD in atrial fibrillation subgroups for all three GFR estimates, although the P for interaction was borderline non-significant for eGFRcys (P for interaction 0.11, Model 2) (Table 4 , Supplementary data, Table S4 ).
