Differences in stratum-specific effect estimates were qualitatively evaluated, without any formal test of the interactions.
We assessed effect modification by considering biologic plausibility, the magnitude and direction of differences in stratum specific risk estimates, and tests of homogeneity.
No differences in stratum corneum lipid composition or increases in transepidermal water loss after a 24-hr irritation test were found between FLG mutation carriers and FLG wild-type individuals 50.
These differences in stratum-specific KL values were most pronounced for studies with greater coverage compared with studies with limited coverage of exposure history by exposure measurement data, and for studies with sufficient compared with insufficient job history information (Table 2).
7 8 A case control study found no difference in stratum corneum hydration and transepidermal water loss between diabetics and controls.
The former includes differential exposure to disease, such as those that occur early in life, those that affect social and physical environments, and work, all of which are associated with differences in social strata.
The differences observed in stratum corneum cell layers depending on location, age and among different individuals corroborate previous findings [26] demonstrating the smallest number of stratum corneum cell layers in genital skin compared to that of face and scalp.
The differences in low-stratum vegetation, pH, leaf litter depth and gravel were the main habitat factors influencing the invertebrate communities of these landscapes.
Several reports on the observed differences in the stratum corneum with premalignant and malignant changes have been reported [ 10, 26, 32, 33].
Most of this difference was in stratum I, in which 50% (five out of 10) of responders benefited vs 10% (two out of 21) of non-responders.
