Trajectory pattern of morning SBP and antihypertensive medication in older patients with anxiety compared with those without anxiety during the pandemic. Abbreviations: SBP systolic blood pressure. The timeline of COVID-19 in China was classified as the pre-epidemic period as the reference (October 21 to November 20, 2019), incubation period (November 21 to December 20, 2019), developing period (December 21, 2019 to January 20, 2020), outbreak period (January 21 to February 20, 2020), and plateau period (February 21 to March 21, 2020). The values in the graphs indicate the adjusted mean monthly average morning SBP within each period of the pandemic among patients with anxiety (blue line) and without anxiety (orange line) after adjustment for age, sex, and body mass index. The gray line indicates the average temperature of the areas where the participants lived during the pandemic
