Effect of valaciclovir on CD4 count decline in untreated HIV: an international randomized controlled trial.
Trial report in The Journal of antimicrobial chemotherapy, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Objectives: To determine the impact of valaciclovir on HIV disease progression in treatment-naive HIV-positive adults. Methods: In this fully blind, multicentre, 1:1 randomized placebo-controlled trial, treatment-naive HIV-1-positive adults with CD4 counts 400-900 cells/mm3 and not meeting contemporaneous recommendations for combination ART (cART) were randomized to valaciclovir 500 mg or placebo twice daily, and followed quarterly until having two consecutive CD4 counts ≤350 cells/mm3 or initiating cART for any reason. The primary analysis compared the rate of CD4 count decline by study arm after adjusting for baseline CD4 count and viral load (VL). Secondary analyses compared the rate of CD4 percentage decline, HIV VL, herpes simplex virus (HSV) recurrences and drug-related adverse events. The trial closed after release of the START trial results in August 2015. Results: We enrolled 198 participants in Canada, Brazil, Argentina and the UK. Median (IQR) age was 35 (30-43) years. Baseline CD4 count was 592 (491-694) cells/mm3 and VL was 4.04 (3.5-4.5) log10 copies/mL. Over 276 person-years of follow-up, CD4 counts declined by 49 cells/mm3/year in the valaciclovir arm versus 58 cells/mm3/year in the placebo arm (P = 0.65). No differences were seen in the rate of change in CD4 percentage (-1.2%/year versus -1.7%/year, P = 0.34). VL was 0.27 log10 copies/mL lower in valaciclovir participants overall (P<0.001). Placebo participants had more HSV recurrences (62 versus 21/100 person-years, P < 0.0001) but similar rates of grade ≥2 drug-related adverse events. Conclusions: Unlike prior trials using aciclovir, we found that valaciclovir did not slow CD4 count decline in cART-untreated adults, although power was limited due to premature study discontinuation. Valaciclovir modestly lowered HIV VL.
