an increasing trendp = 0.06
For trends by number of pesticides used, an increasing trend was of borderline significance for fungicides among those <40 years ( p = 0.06) and significant for an inverse trend among those > 40 years ( p = 0.05).
For trends by number of pesticides used, an increasing trend was of borderline significance for fungicides among those <40 years ( p = 0.06) and significant for an inverse trend among those > 40 years ( p = 0.05).
The interaction term for age was borderline significant for the any pesticides ( p = 0.06) and fungicides ( p = 0.05) classes at the 5 % level of significance (data not shown).
For trends by number of pesticides used, an increasing trend was of borderline significance for fungicides among those <40 years ( p = 0.06) and significant for an inverse trend among those > 40 years ( p = 0.05).
The risk of HL was elevated and showed evidence of a positive trend by number of pesticides used for the younger age group, but not in the older age group (ORs for five or more pesticides were 1.79 (95 % CI 0.93–3.43) for <40 years and 0.84 (95 % CI 0.46–1.54) for > 40 years) and for fungicides (ORs for two or more fungicides were 3.76 (95 % CI 0.96–14.75) for <40 years and 0.19 (95 % CI 0.03–1.39) for > 40 years).
