Although not shown, models 6 and 8 were adjusted for the 7-day patterns identified in Models 5 and 7. The polynomial and trigonometric effects refer to those effects that are coded for the time frame named above each model (i.e., for the 7-day models, these are the weekly polynomial or trigonometric effects while for the 30-day models, these are day of cycle effects); the weekly effects within the 30-day models are not shown but were consistent in both magnitude and significance with those found in the 7-day models
