Unexpectedly, the results indicate that a high number of environmental barriers indoors have a slightly protective effect against mortality risk, even after adjustment for functional limitations.
This association was significant after control for treatment with glucocorticoids, and remained significant after additional adjustment for functional capacity, a disease outcome which is correlated with DAS28 (table 4 column 4 6).
After adjustment for functional status, blood sedimentation rate, and serum albumin levels, no differences in lipoprotein profile emerged between the three groups, with the exception of HDL-C that was lower in VD compared with controls.
Exploratory analyses were performed whereby multivariable logistic regression using both forward selection, and backward elimination, were used to select demographic, health and functional measures independently associated with depressed mood, with and without adjustment for functional impairment within this population and within a subgroup without a previous history of depression.
Although these researchers studied the effects of statins on prognosis of infections, their findings that analyses with more thorough adjustment, including for functional status, showed no association might also extend to prevention of infections.
On the other hand, we performed numerous adjustments of functional annotations for genes from the previously published metabolic model [ 10].
After adjustment for baseline functional status and clinical and demographic variables, blacks had significantly worse summary physical component scores, summary mental component scores, and SAQ Angina Frequency Scale scores.
