If possible, observations of differential gene expression should thus be adjusted for proportions of blood cell subsets, which is not always done.
The level of significance for the association between incidence and 3-year survival was reduced when adjusting for proportion of DCO registrations from P=0.045 to 0.092, although the odds ratio and 95% confidence interval remained unchanged.
However, a unit increase in deprivation score was not significantly associated with receiving any surgery in the original model (OR 0.98, 95% CI 0.95 1.01, P=0.121), but after adjusting for proportion of DCO patients was significantly associated (OR 0.96, 95% CI 0.93 1.00, P=0025).
Many of the associations were altered by adjusting for proportions of CD8+ T cells, CD4+ T cells, natural killer cells, B cells, monocytes, and granulocytes (Table 4).
To control for the effects of neighborhood composition on BMI, our models adjusted for the proportion of residents below the federal poverty line, proportion black, and proportion Hispanic using data from the 2000 U.S. Census summary file 3 (U.S. Census Bureau 2000).
The effect of the proportion of surgical patients as a confounder on outcomes was assessed by comparing crude relative OR (crude OR SAP divided by crude OR SDD) and relative OR adjusted for the proportion of surgical patients (adjusted OR SAP divided by adjusted OR SDD).
Overall work impairment adjusted for the proportion of time absent and present; our data suggest that presenteeism likely accounted for a larger proportion of lost productive time than absenteeism among those who were employed, as has been previously reported for common pain conditions.
The estimated group difference was greater when participation in summer school was distinguished from receipt of the summer program offer in analyses that explicitly adjusted for the proportion of students who failed to comply with their assignment.
The potential confounding factors also adjusted for were proportion of smokers, drinkers, subjects with illness for one year or more before death, and having a sedentary or heavy job; as well as dummy variables for holiday and day of the week.
**Additionally adjusted for the proportion of professional workers in the corresponding census.
