    HDM-stimulated cytokine production. Data are shown as means + SEs for those who are HDM SPT–negative (open bars; n = 113, 117, 101, and 151 at birth, 6, 12, and 24 months) versus those who are HDM SPT–positive (gray bars; n = 33, 32, 34, and 43) at 24 months. Samples with 0 assay values are plotted here and below as 0.5 × detection limit. Differences between groups: P < .05; ∗∗P < .01; ∗∗∗P < .001.
