It's January, ergo it's diet time.
P values for effects of diet, time and diet × time interaction.
No interaction between diet, time and colony was significant.
Two-factorial mixed models were applied to calculate residuals for all variables (fixed factor: diet, time, diet*time) and a random effect (animal).
The high-carotenoid diet significantly increased plasma carotenoid levels compared to initial levels and females fed the low-carotenoid diet (time × diet: F2,50 = 108.12, p < 0.0001, Figure 1a).
Fixed effects were site, gender, diet, time and week, with all interactions between diet, time and week considered, but for site and gender interactions these were restricted to those with diet and week.
Human dosimetry of PCBs should include factors such as exposure through the diet, time spent indoors and outdoors, concentration of PCBs outdoors, and age.
The level of significance was set at 0.05 for testing the effects of diet, time, and their interaction; the interaction was the primary basis of distinguishing between the diets.
Data of the sows were analysed by two-factor analysis of variance (fixed factors diet, time and their interaction) using the GLM Repeated Measures procedure from SPSS 19 (SPSS Inc., Chicago, IL, USA) with time as within subject factor.
At the 3- and 4-week diet time points, mice also had one inguinal mammary gland surgically cleared of endogenous mammary epithelium (cleared fat pad), whereas the contralateral gland was kept intact (intact gland).
