Relatedness between qLAMP and culture assays and cutoffs in different subgroups.

Note: We only used the data from the three-time culture to test the consistency between qLAMP and culture assays. N and BX stand for not found and bronchiectasis, respectively.*In the piecewise linear regression of S. pneumoniae for child patients, all the detected titers were PCs (pathogen candidates), and no breakpoint was found. Therefore, the lowest titer detected in this subgroup is deemed as the upper cutoff.
