M-H, Mantel–Haenszel approach. b Forest plot graphic assessing the relative risk of the presence of IgG Autoantibody to FcεR1α in studies that performed the ASST. M–H, Mantel–Haenszel approach. c Forest plot graphic assessing the relative risk of the presence of IgG Autoantibody to FcεR1α in studies that did not perform the ASST. M–H, Mantel–Haenszel approach
