KITLG and hypertensive disorder: Zhong et al. [57] reported that the peripheral plasma SCF level is higher in patients with non-dipper hypertension than those with dipper hypertension; note that subjects with a decline of less than 10% of nocturnal blood pressure (BP) compared to all day-time blood pressure values are defined as “non-dippers,” while those who suffer from a reduction above 10% of nocturnal BP compared to day-time levels are defined as “dippers”.
