Positive predictive value of sustained virologic response 4 weeks posttreatment for achieving sustained virologic response 12 weeks posttreatment in patients receiving glecaprevir/pibrentasvir in Phase 2 and 3 clinical trials.
Trial report in Journal of viral hepatitis, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 18 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
Sustained virologic response at posttreatment Week 12 (SVR12) is the widely accepted efficacy endpoint for direct-acting antiviral agents. Those with hepatitis C virus (HCV) are presenting younger with milder liver disease, potentially reducing need for long-term liver posttreatment monitoring. This analysis aimed to determine the positive predictive value (PPV) of SVR at posttreatment Week 4 (SVR4) for achieving SVR12 in patients with HCV, without cirrhosis or with compensated cirrhosis, receiving glecaprevir/pibrentasvir (G/P) in clinical trials. An integrated dataset from 20 Phase 2 and 3 clinical trials of G/P was evaluated in patients with 8-, 12- or 16-week treatment duration consistent with the current label (label-consistent group), and in all patients regardless of treatment duration consistency with the current label (overall group). Sensitivity analyses handled missing data either by backward imputation or were excluded. SVR4 PPV, negative predictive value (NPV), sensitivity and specificity were calculated for achieving SVR12 in both groups, and by treatment duration in the label-consistent group. SVR was defined as HCV ribonucleic acid <lower limit of quantification. The label-consistent group and overall group included 2890 and 4390 patients, respectively. PPV of SVR4 for SVR12 was >99% in both groups regardless of treatment duration. Not achieving SVR4 had 100% NPV and sensitivity for all groups. SVR4 measure had 79.5% specificity for identifying patients who did not achieve SVR12. Across 20 Phase 2/3 clinical trials of G/P, SVR4 was highly predictive of SVR12. Long-term follow-up to confirm SVR may not be necessary for certain populations of patients with HCV.
