Estimated time to suppress plasma HIV-1 RNA below 50 copies/mL based upon varying levels of baseline plasma HIV-1 RNA. The estimated required number of days (thick continuous line) with 95% confidence limits (thin continuous lines) are shown. To use this prediction for patients who have a certain baseline value, the population SEs for several baseline values were calculated; the 95% confidence level is t multiplied by the SE, where t = 2 is the Student’s t value for P < 0.05 and df = 116. Time is expressed in number of days, and plasma HIV-1 RNA levels are expressed in log₁₀ copies per milliliter.
