Abstract：
UNASSIGNED: Blood pressure [BP] should be measured using a bare upper arm with an appropriately sized cuff. In practice, it is more convenient to measure BP on a bare arm below a rolled-up sleeve or on a sleeved arm.
UNASSIGNED: A n-of-1 randomized controlled trial was performed to assess the difference between BP measurements over a sleeve or below a rolled-up sleeve.
UNASSIGNED: The study subject was male, white, 72 years old, BMI 26 kg/m2, arm circumference 29 cm, and under stable antihypertensive treatment. The mean of three BP measurements over a thin sleeve was compared with measurements below a rolled-up sleeve. Additional measurements on a completely bare arm, with thicker sleeves and up to three layers were performed. The order of measurements was determined by chance and two oscillometric devices were used. Descriptive statistics, Bland-Altman test and 2-side T test were used for comparisons.
UNASSIGNED: 504 measurements were performed: 50 % over the sleeve and 50 % below the rolled-up sleeve. The mean systolic blood pressure (SBP) was respectively 116.9 ± 9. 2 [95% CI 115.7-118.0, range 96-135] and 122.8 ± 9.2 [95% CI 121.7-124.0, range 103-139, p = 0.001] mm Hg. The mean diastolic blood pressure [DBP] was respectively 67.6 ± 6.8 [95% CI 66.8-68.4, range 52-84] and 71.8 ± 6.8 [95% CI 71.0-72.7, range 55-85, p = 0.001] mm Hg. There was no significant difference between the measurements over the sleeve and on the completely bare arm [n = 94, p = 0.97]. Sleeve thickness with 2 layers up to 3 mm thick did not affect the results.
UNASSIGNED: Blood pressure measurements over a thin sleeve were significantly lower than measurements below a rolled-up sleeve and match measurements on a completely bare arm.

摘要：
■应使用裸露的上臂和适当尺寸的袖带测量血压[BP]。在实践中,在卷起的袖子下方的裸露手臂或带袖子的手臂上测量BP更为方便。
■进行了n-of-1随机对照试验，以评估在袖子上或卷起的袖子下的BP测量值之间的差异。
■研究对象是男性，白色,72岁,BMI26kg/m2，臂围29cm，并在稳定的抗高血压治疗下。将薄套筒上的三个BP测量值的平均值与卷起的套筒下的测量值进行比较。在一个完全裸露的手臂上进行额外的测量，用较厚的袖子和多达三层进行。测量顺序是偶然确定的，并使用了两个示波装置。描述性统计，使用Bland-Altman检验和2侧T检验进行比较。
■进行了504次测量:在套筒上方50%和在卷起的套筒下方50%。平均收缩压(SBP)分别为116.9±9。2[95%CI115.7-118.0，范围96-135]和122.8±9.2[95%CI121.7-124.0，范围103-139，p=0.001]mmHg。平均舒张压[DBP]分别为67.6±6.8[95％CI66.8-68.4，范围52-84]和71.8±6.8[95％CI71.0-72.7，范围55-85，p=0.001]mmHg。在套筒上和在完全裸露的臂上的测量之间没有显著差异[n=94,p=0.97]。2层厚至3mm的套管厚度不影响结果。
■薄袖子上的血压测量值明显低于卷起的袖子下方的测量值，并且与完全裸露的手臂上的测量值相匹配。
