The bold values in the last column (p value) indicate statistically significant differences.
↵* Base: all participants in 18-year follow-up.
↵† Base: participants who underwent SPT and spirometry.
↵‡ p Values are from χ2 tests, except those marked §which are from Fisher's exact tests.
Persistent, onset at/before 8 years follow-up and still current at 18; late-onset, onset between 8 and 18 years; remitted, onset at/before 8 years but not current at 18 years.
