Figure 1.

Mean values at baseline, pre-lockdown and during lockdown in the three groups for systolic (A) and diastolic (B) blood pressure (dotted line = uncontrolled blood pressure group, solid line = unstable blood pressure control, dashed line = controlled blood pressure group). *P < 0.001 (1 year before lockdown vs. lockdown systolic blood pressure), ^#P = 0.001 (pre-lockdown vs. lockdown systolic blood pressure), ^$P = 0.002 (1 year before lockdown vs. lockdown diastolic blood pressure), and ^§P = 0.018 (pre-lockdown vs. lockdown diastolic blood pressure). Grey box refers to the lockdown period. DBP, diastolic blood pressure.
