Figure 4. Terminal digit of the five consecutive systolic and diastolic blood pressure (BP) readings (4890 readings, 2445 each of systolic and diastolic BP measurements taken from each of the 490 participants). Numbers along the horizontal axis denote the terminal digits and the percentages are on the vertical axis. The reference line of 20% denotes the expected. *P for equal proportions (20% expected for each of the five end digits).
