| Waking with breathlessness | 6 | 0 | 5 | 59 | Not calculable | 0.04 * |
| Waking with cough | 11 | 2 | 19 | 38 | 5.5 (1.20, 51.07) | 0.03 * |

| Asthma diagnosis c | 1 | 3 | 1 | 65 | 0.33 (0.01, 4.15) | 0.62 |
a Comparison between crop season and off-season periods, being ‘Yes’ for ‘with symptoms’ and ‘No’ for ‘without symptoms’; b Odds Ratio calculated through McNemar test and Confidence Interval (CI) = 95%; c Asthma diagnosis = at least one asthma attack in the past 12 months and/or confirmation of medication use. * Values with statistical significance.
