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

backgroundThis proof-of-concept study compared lamivudine (LAM) with a newer antiviral agent, adefovir dipivoxil (ADF), in preventing hepatitis B virus (HBV) reactivation in chronic HBV patients undergoing chemotherapy.

methodsHepatitis B surface antigen (HBsAg) positive patients intended to undergo chemotherapy were randomized to receive either LAM 100 mg daily or ADF 10 mg daily. Anti-viral therapy was started 1 week prior to chemotherapy and until 6 months after completing chemotherapy. The primary outcome was HBV reactivation rate. All patients with viral breakthrough were screened for resistance mutations by direct sequencing.

resultsSeventy treatment-naïve patients were consecutively randomized 1:1 to LAM or ADF. The median baseline HBV DNA levels were similar (LAM 3.36 vs. ADF 3.17 log10 copies/mL, p = 0.860). The median duration was 8.3 months on LAM and 10.6 months on ADF (p = 0.220). HBV reactivation was observed in 13/35 (37.1%) on LAM compared with 10/35 (28.6%) on ADF (p = 0.611). The median time to HBV reactivation was 4.6 and 8.1 months, on LAM and ADF respectively. Among these 13 patients, 8/13 (61.5%) on LAM had developed drug resistance mutations but none on ADF had developed drug resistance mutations to ADF (p = 0.003). Both drugs were well tolerated and no severe drug-related toxicities were reported.

conclusionIn this randomized clinical study, adefovir and lamivudine demonstrated similar efficacy in preventing hepatitis B reactivation in HBsAg-positive patients undergoing chemotherapy. In patients whose hepatitis B reactivated, adefovir was associated with a lower resistance profile.
