Only two variables, receipt of emotional support (in both sexes) and contacts with friends were not statistically associated with survival.
We used multivariate logistic regression models, with dependent variables: receipt of a dilated eye exam within the previous year; receipt of a foot exam within the previous year; performing daily SMBG; and all three simultaneously.
The constructs were further evaluated in unadjusted models, and then again after adjusting for demographic and study-related variables (receipt of intervention, study site, age, race, gender, marital status, education and sexual orientation).
Specifically, we distinguished between six categories of women, corresponding to the six possible combinations of the following two variables: receipt of ANC during the pregnancy (i.e., yes, no) and self-reported HIV status before delivery (i.e., not tested, HIV-negative, HIV-positive).
In order to assess the most significant predictors of death in the MRSA pneumonia group, a multivariate logistic regression analysis controlling for APACHE II score was performed with the inclusion of the following variables: receipt of empiric anti-MRSA therapy, presence of renal dysfunction, need for mechanical ventilation, and vasopressor requirement.
As such an experiment is not possible, the problem of endogeneity arises, i.e. the variable remittance receipt is correlated with the residual.
The main treatment variable is receipt of FA in the form of a household food basket ration.
In addition, within stage III colon and stages II and III rectal cancer, we have adjusted for one single variable representing receipt of guideline therapy.
The main exposure variable was receipt of opiate substitution treatment (such as oral methadone, buprenorphine, dihydrocodeine) 21 ascertained from primary care records.
