White blood cell counts in participants with hypertension. Total numbers of A) leucocytes, B) neutrophils, C) monocytes, and D) lymphocytes and E) the neutrophil-to-lymphocyte ratio (NLR) were analysed in study participants without hypertension (grey dots) and with hypertension (red dots). Hypertension was defined as systolic blood pressure ≥ 140 mmHg and/or diastolic blood pressure ≥ 90 mmHg. Lines and error bars represent mean ± SEM. Unpaired t-test was used to assess significance. P value < 0.05 was considered significant. (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article.)
