– However, no correlation strength was found between NA/MHMA ROC or AD/MHMA ROCs and high histamine ROC (Table 3 ), but – a marginally significant negative relationship was found between histamine and free Cu/Zn ( n = 134, rho = −1.95, P = 0.052) that was supported on SEM analysis by a negative coefficient between these two variables ( n = 134, z = −1.95, P = 0.052).
