^*Model includes 8340 (99·4%) of 8394 cohort participants; the original model intercept coefficient was −6·65 (95% CI −7·21 to −6·10), suggesting that the probability of hospital admission for children with no predictors was 0·14%.

^†Odds ratios calculated using shrunken estimates from the bootstrap internal validation calibration slope.

^‡Defined as present if asthma in medical notes and asthma drugs issued in the previous 12 months.

^§Including after cough.
