Within the context of certain limitations, the authors did a commendable job addressing the potential for bias from differences in beneficiaries' baseline health status
. As individuals move between systems, it becomes increasingly difficult to distinguish new from existing comorbidities.
While there remains a clear role for the [CD4.sup.+] count in establishing baseline health status
and focusing treatment provision on patients at higher risk of death, the role of [CD4.sup.+] in the monitoring of ART efficiency once patients have started ART is under scrutiny.
Based on baseline health status
(largely driven by [HbA.sub.1c] levels), estimated costs per patient were $42,032 in the clinic group and $37,065 in the comparison group.
Stratified analyses revealed no statistically significant interactions with age, sex, race, marital status, income, neighborhood poverty, or baseline health status
Different socio-demographic characteristics and baseline health status
between populations may be another reason for this difference.
* Obtain a baseline health status
. A complete physical will identify any reasons to restrict or modify activity.
In addition, the time between the start of an exacerbation and recovery to baseline health status
was a significant 18% shorter for sudden-onset vs.
Moderator variables such as reason for weight loss (intentional, unintentional), baseline health status
(healthy, unhealthy), baseline BMI (normal, overweight, obese), method used to estimate weight loss (measured weight loss, reported weight loss) and whether models adjusted for physical activity (adjusted data, unadjusted data) were used to classify subgroups for separate analysis.
The association between waist circumference and mortality persisted after further adjustment for smoking, baseline health status
, and BMI but not after additional adjustment for fitness.
A total of 59% were men, 95% were white, and they had a generally good baseline health status
Baseline health status
was assessed by recall at the 12-month interview.
The health equation specifies that health status in 1998 is a function of household wealth in 1993, after controlling for demographic characteristics, education levels, marital status, and baseline health status
