Method description to mark maximum flicker light-induced dilatation. (A) Method I marked the maximum flicker light-induced dilatation response (FID) ten seconds into the flicker till three seconds after the flicker phase (seconds 41–53, marked in red), based on the median curve of three identical flicker cycles. (B) Method II marked absolute maximum FID three seconds into the flicker till three seconds after the flicker phase (seconds 48–53, marked in red). (C) Method III averaged the last three seconds during and the first three seconds after the flicker phase (seconds 48–53, marked in red), which represents the standard report provided by the manufacturer (IMEDOS Systems). aFID arteriolar flicker light-induced dilatation response.
