The between-school variation remains significant and is only modestly reduced after controlling for additional variables.
We controlled for additional variables including insurance status, ease of accessing health care, Body Mass Index (BMI), the presence of smokers in the house, and parental asthma status all of which are potential risk factors for asthma.
KAM impulse explained significant variation in the ratio uCTX-II;sCPII even when controlling for additional variables (p = 0.04).
We have controlled for additional variables, both individual maternal characteristics and contextual SES variables, and assessed multiple pollutants, using both linear and categorical forms of exposure.
These cases highlight how the use of colitis mouse models in gut microbiota research will require controlling for additional variables beyond the common confounders (such as host genetic background and environmental factors).
Therefore, the odds of being moderately addicted to Khat compared to a low level of dependence increased by a factor of 1.67 for those who live in rural areas compared to living in urban areas, after controlling for additional variables in the model.
Of the 17 studies of program effects, 11 controlled for additional variables in the comparison of retention and provision of care between people who did and did not participate in a financial-incentive program [ 12, 48, 52, 53, 65, 81, 84- 88].
This is in agreement with the findings of our study; however, our affirmation of this association was confirmed even after controlling for several additional variables and finer categories of utilization.
Since cavitary disease is positively correlated with transmission and thus a measure of "virulence" [ 36], we decided to further investigate this difference, while controlling for the additional variables associated with cavitary TB.
Again, the association between race/ethnicity and use of any health care remained statistically significant after controlling for additional individual level variables (Table 2).
