1 · What the graph read from 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.

2 · The registry

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

We report a population pharmacokinetic (PK) and pharmacodynamic (PD) model of orally administered ribavirin in patients with chronic hepatitis C virus (HCV) infection enrolled in a multicenter clinical trial, including the estimation of covariate effects on ribavirin PK parameters and sustained viral response (SVR). Ribavirin concentrations obtained from 144 patients, consisting of n = 71 African American (AA) and n = 73 Caucasian Americans (CA), during 24 weeks of therapy were best described by a two-compartment model with first-order absorption and elimination parameterized in terms of apparent oral clearance (CL/F), apparent central volume (Vc/F), apparent peripheral volume (Vp/F), and apparent intercompartmental clearance (Q/F). The typical population parameters were CL/F (19.0 L/h), Vc/F (1,130 L), Vp/F (4,020 L), and Q/F (38.6). The Vp/F was approximately 50% greater in AA compared to CA. Significant covariates in the SVR model included IL-28B genotype, homeostasis model assessment of insulin resistance, and ribavirin exposure during the first week (AUC(0-7)). The population PK and logistic regression models both described the observed ribavirin concentration data and SVR data well. These findings suggest that optimization of ribavirin plasma concentrations during the first week of ribavirin dosing is most critical in AA patients in order to increase the rate of SVR, especially those with the IL-28B TT genotype.
