*Data given for 212 participants who experienced at least 1 upper respiratory infection, were seen by a study physician, and had a nasopharyngeal swab collected for bacterial culture. An additional 82 enrollees were excluded from the study because they did not experience an upper respiratory infection and did not have a nasopharyngeal swab collected for bacterial culture. Some numbers do not add up to 212 because of missing data.
†No. hours and days/week in day care were grouped into any or none. Environmental exposure to tobacco smoke was based on parental self-report.
