Abstract

fetched live from OpenAlex

AIM: To conduct a network meta-analysis (NMA) to determine the comparative efficacy, as measured by sustained virological response (SVR), between boceprevir (BOC), telaprevir (TEL), faldaprevir (FAL), simeprevir (SIM) and sofosbuvir (SOF) in combination with peginterferon-ribavirin (PR) against a control of PR. DESIGN: A literature search was conducted to identify randomized controlled trials (RCTs) including adult patients with hepatitis C virus genotype 1 who were naive to any prior therapy. RCTs assessing standard duration therapy (SDT) or response-guided therapy (RGT) BOC, TEL, FAL, SIM or SOF in combination with PR against a control of PR were eligible for inclusion. All RCTs must have provided SVR at either 12 or 24 weeks post-therapy cessation. RESULTS: We included nine RCTs. All direct-acting antivirals (DAAs) were found to perform better than PR. Additionally, SDT FAL was found to be better than the 240 mg RGT FAL regimen with the PR lead-in. A sensitivity analysis excluding RCTs with only SVR at 12 weeks was consistent with the results of the primary analysis. A sensitivity analysis removing an RCT assessing SIM that reported SVR of >60% in the PR control group additionally found that RGT SIM was superior to the 240 mg RGT FAL regimen with the PR lead-in. DISCUSSION: Our analyses indicate that SDT and RGT regimens of DAAs plus PR do not differ greatly in terms of SVR among treatment-naive hepatitis C genotype 1 patients. More advanced Bayesian network meta-analyses are likely needed to incorporate a comprehensive evidence base, expanding beyond randomized clinical trials.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
