Table 2.
Calculated odds of SWMC boys versus SWMC girls developing interstitial markings based on age, sex, and the combination of both.
b | z | p > |z| | |
---|---|---|---|
Age | –0.14725 | –2.279 | 0.023 |
Sex | –2.3777 | –2.454 | 0.014 |
Age and sex | 0.27763 | 2.874 | 0.004 |
Abbreviations: b, raw coefficient; z, z-score for test of b = 0; p > |z|, p-value for z-test. Probabilities for boys increased with age, likely the result of their significantly higher outdoor exposures and their moderate to severe physical exercise while outdoors.
