Combination therapy based on pegylated interferon alfa improves the therapeutic response of patients with chronic hepatitis B who exhibit high levels of hepatitis B e-antigen at 24 weeks: A retrospective observational study.

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
Pegylated interferon alpha (PEG-IFN-α) is a first-line treatment for patients with chronic hepatitis B (CHB), but its efficacy varies from individual to individual. Early discrimination between responder and non-responder patients is important for optimal clinical management. In addition, low therapeutic efficacy is still a major issue; thus, treatment timing should be optimized.We reviewed our experience with hepatitis B e-antigen (HBeAg)-positive patients treated with PEG-IFN-α, alone or in combination with nucleoside analogues (NAs), from 2009 through 2014. Collected data included both general characteristics of 113 patients and laboratory data at baseline and at treatment weeks 12, 24, 52, and 76. The endpoint was HBeAg seroconversion at week 76.A total of 113 patients with changed to or start of NAs therapy were included in this study. At the end of treatment, 44 (38.9%) patients exhibited HBeAg seroconversion. Patients with HBeAg seroconversion had lower baseline HBeAg (475.5 vs 751.7; P = .007). The incidence of HBeAg seroconversion was significantly higher among patients with HBeAg ≤ 500 signal-to-cutoff ratio (S/CO) (OR = 2.60, 95% CI: 1.16-5.83, P = .02) at baseline, HBeAg S/CO ≤ 20 (OR = 3.37, 95% CI: 1.47-7.73, P = .003), or a higher than 10-fold HBeAg drop (OR = 3.55, 95% CI: 1.50-8.37, P = .003) at week 12 or HBeAg ≤ 15 S/CO (OR = 10.35, 95% CI: 4.09-26.20, P < .001) at week 24. Subgroup analyses demonstrated that in patients with HBeAg >20 S/CO at 24 weeks, the addition of NAs treatment may increase HBeAg seroconversion (23.3% vs 0%, P = .03).HBeAg levels had an impact on the rate of serological conversion in CHB patients receiving PEG-IFN-based treatment. Combination therapy with NAs should be considered in CHB patients maintaining a high HBeAg level after 24 weeks of PEG-IFN monotherapy.
