p(SR) & p(OR) in unweighted GSMA.A. asthma. B. bronchial hyper-responsiveness. C. total serum IgE. D. skin prick test response. A p(SR) of p < 0.000417 = significant linkage, p < 0.0083 = suggestive linkage. p(SR) & p(OR) data were transformed using f(x) = 0.05/x and plotted on a log10 scale to improve clarity.
