Line charts showing female and male profiles of hypertension by age for JNC7 and ACC/AHA definitions — Age/sex-specific profiles of hypertension prevalence in Sri Lankan adults according to JNC7 and ACC/AHA 2017 definitions, SLHAS 2018–2019.

Notes: Panel A displays the smoothed profile of HTN (JNC7) with age, and panel B displays the smoothed profile of HTN (ACC/AHA). Both are estimated using the weighted data for participants aged 18–85 years by fitting restricted cubic splines with six knots to allow for nonlinear relationships. Shaded regions denote 95% confidence intervals.
