The relationships of symptoms and blood pressure were studied in a population sample of 1926 individuals. Analysis of covariance showed that none of the 13 symptoms was significantly related to systolic or diastolic BP. Symptoms were more strongly associated with confounding variables.
在一个包含1926人的人群样本中研究了症状与血压之间的关系。协方差分析表明,13种症状中的任何一种都与收缩压或舒张压没有显著关联。症状与混杂变量的相关性更强。
