This effect was mainly due to smaller S1 amplitudes in the patient group. SZ patients exhibited less evoked beta and gamma power, particularly at the 0-100 ms time point, in response to S1. Early (0-100 ms) evoked beta and gamma responses were critical in determining the S1 amplitude and extent of P50 gating across the delay interval for both HC and SZ. CONCLUSION Our findings support a disruption in initial sensory registration in those with SZ, and do not support an active mechanism throughout the delay interval. The degree of response to S1 and early beta and gamma frequency oscillations in the delay interval provides information about the mechanisms supporting auditory sensory gating, and may provide a framework for studying the mechanisms that support sensory inhibition. BACKGROUND AND AIMS The association between coronary heart disease (CHD) caused by atherosclerosis and periodontitis has already been established. Peripheral arterial disease (PAD) is also caused by atherosclerosis, but the characteristics of the target artery and the disease are different from those of CHD. The aim of this study was to determine whether the risk of PAD was high in patients with periodontitis. METHODS For this study, we used data from the Korean National Health Insurance Service-Health Screening Cohort (NHIS-HEALS) database that were collected between January 2003 and December 2014. We compared the incidence of PAD between patients with periodontitis and a matched control group selected from among 514,832 people enrolled in the NHIS-HEALS database to confirm the increased incidence of PAD in patients with periodontitis. RESULTS The incidence per 1000 person-years was 2.40 in the patients with periodontitis and 2.08 in the matched controls. The hazard ratio (HR) of PAD in the periodontitis group compared with that in the matched group
