Figure 2. Time to First Detection of Atrial Fibrillation at 12 Months in a Study of Long-term Continuous Cardiac Monitoring vs Usual Care on Detection of Atrial Fibrillation (AF) in Patients With Stroke Attributed to Large- or Small-Vessel Disease.

Figure 2.

At 6 months, the AF incidence was 7.9% in the ICM group vs 0.8% in the control group (hazard ratio, 9.9 [95% CI, 2.3-43.5]; P < .001). The median (interquartile range) time from randomization to AF detection was 99 (36.0-235.0) days for the insertable cardiac monitor (ICM) group and 181 (86.0-231.0) days for the control group. The median (interquartile range) observation time was 365 (365-365) days for all randomized patients for each group.
