  • Data are presented as probabilities. A: persistent cough; B: transient cough; C: atopic persistent wheeze; D: nonatopic persistent wheeze; E: transient viral wheeze. #: questions were asked only to those who reported wheeze ever in the respective survey. The residual category for these variables is “no” to wheeze ever. : residual category is “no cough”; +: 0.25–0.50; §: 0.50–0.75; ƒ: 0.75–1.00.
