Serological and virological response in patients with hepatitis B virus genotype E treated with entecavir or tenofovir: a prospective study.
Article in Archives of virology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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
European clinical practice guidelines (EASL) on chronic hepatitis B (CHB) recently recognized the importance of migration flows in the changing hepatitis B virus (HBV) epidemiology in low-endemic European countries. The role of different genotypes in nucleos(t)ide analogue (NA) treatment is still unknown. In the case of genotype E, which is mainly circulating in West Africa, a quantitative decrease in the level of HBsAg (qHBsAg) during treatment with entecavir (ETV) predicts a longer time to HBsAg loss when compared to genotypes A and D. We prospectively evaluated qHBsAg decline in HBeAg-negative CHB patients infected with HBV genotype E who were treated with tenofovir 245 mg (TDF) or ETV 0.5 mg from 2008 to 2014. Sixty-five West African patients (58; 89.2% males) were enrolled. The median age was 29 years, and the most prevalent route of transmission was familial (25; 38.5%). Median liver stiffness was 7.4 kPa, HBV-DNA was 4.7 Log IU/ml, and qHBsAg was 3.4 Log UI/ml. According to clinical evaluation, 40 patients (61.5%) started ETV treatment, whereas 25 patients (38.5%) started TDF treatment. The decline of qHBsAg in ETV patients was significantly lower than in TDF patients after 5 years of treatment (0.31 vs. 0.68 LogIU/mL, p < 0.001). At the same time points, a significantly higher virological non-response rate was observed in ETV patients (p < 0.001). Despite the partial and non-response rates observed in the ETV group, no mutations associated with drug resistance were detected in these subjects. In genotype E infections, ETV treatment results in a significantly lower decline in qHBsAg and higher rates of virological non-response after 5 years. TDF could represent the optimal choice.
