Effectiveness of Elbasvir/Grazoprevir in patients with hepatitis C virus genotype 1 infection and chronic kidney disease in the United States veterans population.
Article in Antiviral research, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
BACKGROUND &
aimsRandomized controlled trials of EBR/GZR have reported high treatment efficacy, safety and tolerability in patients undergoing dialysis. However, real world effectiveness data for EBR/GZR in this population is lacking. We evaluated the effectiveness of EBR/GZR in an HCV-infected population with all stages of CKD including dialysis compared with control patients with estimated glomerular filtration rate (eGFR) ≥60 in the US Department of Veterans Affairs (VA).
methodsWe conducted a retrospective cohort study of patients with chronic HCV genotype 1 infection with EBR/GZR prescriptions dispensed during February 1, 2016-August 31, 2017 in 128 VA Medical Centers. We collected patient information regarding history of dialysis, end stage renal disease (ESRD), and/or eGFR values. We measured SVR based on undetectable HCV RNA at least 4 weeks after the completion of treatment. We examined SVR rates by CKD stage compared to control patients and within patient subgroups using logistic regression models.
resultsWe identified 5961 patients (42.5% genotype 1a, 55.0% genotype 1b) who met eligibility criteria and completed a EBR/GZR treatment course (≥11 weeks). Approximately 73.2% (n = 4361) had eGFR ≥60 who served as control patients, 14.4% (n = 860) had Stage 3 CKD, and 12.4% (n = 740) had Stage 4-5 CKD or ESRD. Of patients with Stage 4-5 CKD/ESRD, 76.1% underwent dialysis (n = 563). The overall SVR was 96.7% in all patients, 96.4% for eGFR≥60, 98.3% in Stage 3 CKD, and 96.5% in Stage 4-5 CKD/ESRD. No statistically significant differences were found in the SVR rates in patients with or without dialysis in the Stage 4-5 CKD/ESRD patients (adjusted OR 0.91; 95% CI 0.56-1.47 and OR 1.74; 95% CI 0.63-4.81) compared with those with eGFR≥60.
conclusionWe found EBR/GZR was effective in patients with HCV GT1 infection regardless of CKD severity or receipt of dialysis in the US VA population.
