1 · What the graph read from it

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.

2 · The registry

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

backgroundValacyclovir, an orally administered pro-drug of acyclovir, is utilized in the therapy of herpes simplex and herpes zoster infections. Little data regarding the pharmacokinetics, safety and tolerability are available for pediatric patients. This report describes acyclovir pharmacokinetics following valacyclovir administration in immunocompromised pediatric patients, compares pharmacokinetic parameters following oral valacyclovir and IV acyclovir, and provides a limited assessment of efficacy in the setting of active herpes zoster infection. PROCEDURE: A total of 37 immunocompromised children were enrolled on one of two studies. Pharmacokinetic data are available for 32 patients following valacyclovir (15 mg/kg) administration, 11 of whom also had pharmacokinetic sampling following IV acyclovir administration. Three patients received valacyclovir as treatment for herpes zoster infections.

resultsMean (+/-SD) C(max) values for acyclovir following oral valacyclovir were 18.8 +/- 7 microM with a total exposure of 4,106 +/- 1,519 microM min. The mean bioavailability of acyclovir from valacyclovir was 64%. Grade 1 nausea and emesis, which occurred in five patients was the only valacyclovir-related toxicity. Two of the three patients treated for herpes zoster had complete scabbing of lesions by day 9.

conclusionValacyclovir (15 mg/kg) was well tolerated in pediatric patients and demonstrated excellent bioavailability. Consideration should be given to the use of oral valacyclovir for the treatment of herpes zoster in clinically stable pediatric oncology patients.
