is there any association between skin prick test results and Peak Flow metry in workers with asthma?

Dear sir, is there any association between skin prick test results and Peak Flow metry in workers with asthma?

We have researched a group of occupational asthmatics and found that both atopics (positive skin prick tests to common environmental allergens) and non atopics (negative skin prick tests)have a similar diurnal variation in their peak flow (difference bewteen the best and worst peak flow each day divided by the record mean). The atopics averaged 23% diurnal variation and the non-atopics 20%, both of which are in the asthmatic range.
