HBsAg quantification predicts off-treatment response to interferon in chronic hepatitis B patients: a retrospective study of 250 cases.
Article in BMC gastroenterology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
backgroundFor chronic hepatitis B (CHB) patients without willingness to extend the routine duration of interferon (IFN) therapy, it is important to identify patients who will benefit from treatment cessation. Hepatitis B surface antigen (HBsAg) quantification is recommended for management of IFN therapy. At present, the understanding on end-of-treatment (EOT) HBsAg level predicting post-treatment response to IFN is still finite.
methodsA total of 2451 non-cirrhosis, HBsAg-postive patients treated with IFN-based therapy during the period from December 2010 to December 2017 at Nanfang Hospital were enrolled in this study. Serum HBsAg levels at EOT were measured to evaluate the associations between EOT HBsAg levels (Group 1, HBsAg > 0.05 and ≤ 10 IU/mL; Group 2, HBsAg > 10 and ≤ 200 IU/mL; Group 3, HBsAg > 200 IU/mL) with post-treatment HBsAg loss. Chi-squared, t-test,,Kaplan-Meier analysis, Cox regression analysis, and Multivariate Logistic regression analysis were used to analyse and evaluate differences between the there groups.
resultsThe cumulative HBsAg loss rates 5 years after treatment in Group 1-3 were 30.4% (17/56), 9.8%(4/41) and 0%(0/153) (p < 0.001). An EOT HBsAg level of > 10 IU/mL showed relatively high negative predictive value (NPV) of up to 97.9% for HBsAg loss. Low baseline HBsAg level < 25,000 IU/mL, on-treatment HBsAg decline > 1 log10IU/mL at week 24 and EOT HBsAg level ≤ 10 IU/mL were found significantly associated with HBsAg loss. A total of 6 patients have achieved HBsAg loss at EOT and 17 patients with EOT HBsAg level ≤ 10 IU/mL have achieved post-treatment HBsAg loss. Baseline characteristics, dynamic changes of on-treatment HBsAg and duration of IFN therapy were balanced across patients with EOT or post-treatment HBsAg loss.
conclusionEOT HBsAg level can serve as a monitoring indicator for IFN therapy. EOT HBsAg level ≤ 10 IU/mL was found to lead to high rate of post-treatment HBsAg loss. For patients without willingness to extend IFN treatment, off-treatment follow-up could be considered when HBsAg level decreased to ≤10 IU/mL.
