Lamivudine therapy for korean children with chronic hepatitis B.

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
purposeLamivudine is known to be very effective in suppressing hepatitis B virus replication and virus induced necroinflammation. The aim of this study was to evaluate lamivudine therapy efficacy, predictive factors, breakthrough, prevalence of YMDD mutation, and relapse rate in Korean children with chronic hepatitis B. MATERIALS AND
methodsBetween August 1999 and February 2005, 60 children on lamivudine therapy for chronic hepatitis B were enrolled. Treatment response was defined as alanine aminotransferase (ALT) normalization, and HBeAg and HBV-DNA disappearance.
resultsSeroconversion rates of HBeAg and HBV- DNA were 42% and 53%, respectively, and ALT normalization rate was 88%. Seroconversion rates of HBeAg (60.0%) and anti-HBe (60.0%) were higher in patients younger than 6 years. Seroconversion rate of HBV-DNA (68.4%) and normalization rate of serum ALT (94.7%) were highest in patients between 6 and 12 years. Seroconversion rates of all HBV markers were lowest in patients older than 12 years. Predicted 3 year cumulative seroconversion rates, were 70%, 68% for HBeAg, HBV-DNA, respectively. These were calculated by Kaplan-Meier method. Cox proportional hazard regression model showed that pre-treatment ALT was a positive predictive factor for seroconversion of HBeAg and HBV-DNA. Breakthrough phenomenon was noted in 6 patients, and 3 had a YMDD mutation.
conclusionLamivudine therapy had a significant effect on HBeAg seroconversion and HBV-DNA disappearance, and ALT normalization for Korean children with chronic hepatitis B.
