Triple combination superior to double combination
Abstract:
Patients taking a triple combination of AZT, ddI, and nevirapine appear to have better surrogate markers than those taking the double combination of AZT and ddI, according to 241 AIDS Clinical Trials Group (ACTG) researchers. The triple combination resulted in a 40 percent increase in T-cells over baseline, which persisted through 40 weeks of the study. The triple combination also produced greater decreases in the viral load. Although the trial was not designed to evaluate clinical endpoints, there appeared to be no difference in clinical endpoints except in patients with fewer than 50 T-cells or where there was a trend toward fewer clinical endpoints with the triple combination. Nevirapine, an investigational nonnucleoside reverse transcriptase, is available only through clinical trials.

Multiple Comparison Tests
It would be easy to compare two samples using a significance alpha level of 0.05. In other words, there is only one sample pair to be compared. However, it would be difficult to identify a significantly different sample if the number...
Equivalent Couples
Two couples are considered to be equivalent if they produce the same rotational effect on a rigid body. In other words, the two couples have the same magnitude and act in the same direction, causing the same angular displacement or acceleration in the body.
For instance, consider two couples lying in the plane of the page, with one having a pair of equal...
