Interrupted time series (ITS) approach comparing the incidence of a new diagnosis of hypertension in the 3-year period before the COVID-19 pandemic (i.e., 2017–2019) to the 3 years during the COVID-19 pandemic (i.e., 2020–2022) and including the year 2023, when the pandemic was declared over. The blue line represents the observed incidence with 95% confidence bands; the red dashed line represents the counterfactual line with 95% confidence bands
