In preliminary analyses minor sectors were examined as: a) categorical variables (minor sector of longest [lagged] duration, a mutually exclusive classification); and b) continuous variables (lagged durations of employment in all minor sectors) [ 36].
There were considerably more cases than controls among subjects whose minor sector of longest duration was a) agriculture: 37 vs. 23 cases, b) food manufacturing: 30 vs. 10, c) automotive plastics manufacturing: 26 vs. 9, d) laundry/dry cleaning: 8 vs. 2 and e) bars-gambling (16 vs. 11) (Table 1).
When classified on minor sector of longest (lagged) duration of employment, and analyzed with conditional logistic regression, several demographic and reproductive risk factors exhibited strong, statistically significant associations as did several minor sectors of employment (Table 4).
Employment duration terms (linear and squared) were statistically significant and included in all matched analyses (except the initial descriptive analysis by minor sector of longest duration).
Several minor sectors potentially of interest for breast cancer investigation, such as textiles, footwear, printing, ceramics, furniture, jewelry and electronics, were combined as light manufacturing due to small numbers of cases.
While the transportation sector accounts for about 25percentt of the global energy-related carbon dioxide emissions, rail represents a minor fraction of that total.
Both the health sector cost and the societal cost were at similar levels in the two arms, and there was only a minor advantage of RDTs over microscopy in terms of the proportion of correctly treated patients.
She was a minor William Cowper of sorts.
A minor loss of nerve, perhaps.
It is a very minor change and it is only a minor part of their susceptibility".
