Gender differences are detectable in WBLogTREC/ml when females (open circles/ dashed regression line) are compared with males (closed circles—solid regression line) at any age. There is a statistically significant difference between the two groups after correcting for age (p = 0.043). The negative correlation with age is maintained in each population. (A single sample (male; TREC/ml—2.58) was removed from this analysis because it was an outlier exerting significant influence on the result when included).
