These results are robust to controlling for possible non-random selection effects.
A general linear model was used to compare outcome scores between the two groups while controlling for possible confounders.
Also controlling for possible confounding effects as depression, time elapsed from CHT or age, the differences between groups in the network evidenced by MVPA was still significant.
After controlling for possible confounding factors, the development of PIH was associated with increased mortality (OR = 2.17; CI: {1.25, 3.77}; P = 0.006).
To determine the relationship between some characteristics (cost, intensity, quality) of prescriptions issued by general practitioners in a health district and their patient loads, controlling for possible confounders.
Factors with a p-value <0.1 were put in a multiple Poisson regression model in order to estimate the same associations after controlling for possible confounders.
The random effect captures the effects of unmeasured variables that might explain some of the differences in cortisol among women, thus controlling for possible correlations among cortisol measurements from the same woman.
We did these comparisons in select groups, chosen because each contained a large number of sites that were recorded from approximately the same time of year in all animals, controlling for possible seasonal effects.
The Mantel-Haenszel test for 2 x 2 contingency tables to test for association between innervation and muscle source (side) in individual animals while controlling for possible effects of different animals.
Organisational functional connectivity characteristics (the number of connections and level of local connectedness gamma) were compared between ALS patients and healthy controls using GLM statistics, controlling for possible effects of age.
Experiments II and III were designed to further strengthen this conclusion by separating the two factors "sleep-deprived vs. non-deprived state at retrieval" and "sleep vs. wakefulness after learning", and carefully controlling for possible circadian influences.
