At 30 or 90 days of age, the rats were tested for food intake in response to either leptin or saline after being fasted for 18 hours.
According to the continuum of care model for HIV in correctional settings (O'Connell et al. 2013), all persons are tested for HIV at intake to a correctional facility unless they specifically decline (i.e., opt-out testing).
From the data, it appears that not all mice were tested for initial saline intake.
When tested for circadian food intake, an SCN output system, 18-month-old WT control mice exhibit a 4-6-h shift in circadian food intake compared to 5-month-old mice [ 195].
In addition, we also stratified analyses for coffee intake according to established liver cancer risk factors and tested for interactions between coffee intake and stratified variables in logistic regression models.
As the sugar composition was similar among the different honeydews, we tested for differences in honeydew intake as an alternative explanation for the observed differences in parasitoid performance.
We tested for additive interactions between alcohol intake (categorical) and race/ethnicity and alcohol intake (categorical) and BMI (continuous) with all confounders within the model with and without cross product terms.
In addition, we tested for possible interactions between magnesium intake and sex, ethnicity, family history of diabetes, and BMI by adding corresponding multiplicative interaction terms in the models, followed by the likelihood ratio test.
We further tested for effect modification between isoflavone intake and other covariates (age, sex, cigarette smoking, alcohol drinking and body mass index) in colorectal adenoma through the addition of multiplicative interaction terms into the model, but found no statistically significant P-value for interaction (data not shown).
The FFQ was designed in order to cover the usual Uruguayan diet and allowed the calculation of total energy intake: it was tested for reproducibility with good results (results available).
