a positive trendp < 0.001
After calculating the AAPC between 1990 and 2021, we observed a positive trend in age-standardized incidence (0.25% [95% CI, 0.21% to 0.30%], p < 0.001) and prevalence rates (0.20% [95% CI, 0.18% to 0.22%], p < 0.001) for IHD, while age-standardized mortality (−0.56% [−0.64% to −0.48%]) and DALY rates (−0.55% [−0.63% to −0.46%]) showed a decline.
