The findings of this article1 underscore the need for enhanced meteorological monitoring on ground ozone concentrations as well as the need for early detection and targeted intervention of respiratory diseases in vulnerable members of society to reduce the escalating burden of respiratory diseases worldwide. However, from the viewpoint of data interpretation and extrapolation, we have 2 concerns.
