To our knowledge, our study is the first to consider past use of OC and other patterns of OC use and IGF-1 levels in premenopausal women and suggests a potential long term effect of past use of OC on IGF-1 depending on when they are first started.
In a qualitative study, we interviewed selected caregivers from the original study sample [ 28] and identified other patterns of use, for example, periods of intensive uses separated by extended nonuse periods.
However, the effect of other patterns of OC use, in particular past use and timing of use during life on circulating IGF-1 has not been studied.
We examined the association between other patterns of use not measured in earlier studies, such as past use, and plasma IGF-1 levels among 328 premenopausal women aged 18 to 21 and 31 to 40.
Point estimates of odds ratio for sex, other patterns of NSAID use, prior dispensation of gastroprotective agents, prior referral to a gastroenterologist, prior gastrointestinal procedures, prior use of antidepressants and benzodiazepines, and anticoagulants were greater for celecoxib than for rofecoxib, but the difference was not significant.
This approach is precisely what should be extended to other patterns of disease and used as the rule for reducing environmental health risks rather than as a novel exception.
This relationship can guide and/or alert the software engineer in the use of other patterns that may complement the specification when applying a certain pattern, thus improving completeness in the RD. .

Note that, apart from pesticide use patterns, SUPERB also collected use patterns of other consumer products, food intake frequency, and time activities, and one telephone or web survey could easily take one hour or more, which drastically increased participant burden and may have increased the participant drop-out rate in both types of surveys.
Other researchers have found similar patterns using other sources of data (Burkhauser et al. 2002; Burkhauser et al. 2003 1.
