OBJECTIVE: To investigate blood pressure rhythm(BPR)in Yin deficiency syndrome of hypertension(YDSH)patients and develop a random forest model for predicting ***: Our study was consistent with technical processes and specification for developing guidelines of Evidence-based Chinese medicine clinical practice(T/CACM 1032-2017). We enrolled 234 patients who had been diagnosed with primary hypertension without antihypertensive medications prior to the enrollment. All participants were divided into Yin deficiency group(YX, n = 74) and non-Yin deficiency group(NYX, n = 160).Participants were professionally grouped by three experienced chief Traditional Chinese Medicine(TCM)physicians according to four examinations(i.e.,inspection, listening and smelling, inquiry and palpation).We collected data on 24 h ambulatory blood pressure monitoring(ABPM) and YDSH rating scale. We divided 24 h of a day into 12 two-hour periods [Chen-Shi(7:00-9:00), Si-Shi(9:00-11:00), Wu-Shi(11:00-13:00), Wei-Shi(13:00-15:00), Shen-Shi(15:00-17:00), You-Shi(17:00-19:00), Xu-Shi(19:00-21:00), Hai-Shi(21:00-23:00), ZiShi(23:00-1:00), Chou-Shi(1:00-3:00), Yin-Shi(3:00-5:00), Mao-Shi(5:00-7:00)] according to the theory of “midnight-midday ebb flow”. We used random forest to build the diagnostic model of YDSH, with whether it was Yin deficiency syndrome as the outcome. RESULTS: Compared with NYX group, YX group had more female participants with older age, lower waist circumference, body mass index(BMI), diastolic blood pressure(DBP), and smoking and drinking rate(all P < 0.05). The YDSH rating scores of YX group [28.5(21.0-36.0)] were significantly higher than NYX group [13.0(8.0-22.0)](P < 0.001), and the typical symptoms of YX group included vexing heat in the chest, palms and soles, dizziness, dry eyes, string-like and fine pulse, soreness and weakness of lumbus and knees, palpitations, reddened cheeks, and tinnitus(all P < 0.05). The ratio of non-dipper hypertension in YX group was higher t
