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

aimsPulmonary arterial hypertension (PAH) is a syndrome characterized by elevated pulmonary artery pressure. We developed a population pharmacokinetic (PPK) model using combined plasma drug concentration data from Japanese paediatric (<15 years) and adult (≥15 years) patients with PAH to investigate the pharmacokinetic characteristics of PAH treatments (sildenafil, tadalafil, bosentan and ambrisentan).

methodsPPK analysis was conducted using a nonlinear mixed-effects modelling approach. A one-compartment model was selected as the structural model, and an exponential error model was used to describe interindividual variability. Individual patient clearance (CL), adjusted for bioavailability (F) using Bayesian estimation based on the PPK model, was used to estimate the steady-state plasma concentrations (C

resultsPPK analysis was performed on data from 35 paediatric and 16 adult subjects to estimate pharmacokinetic parameters. The population mean CL/F values for sildenafil, tadalafil, bosentan and ambrisentan were estimated at 60.6, 1.76, 8.85 and 0.594 L/h, respectively. Covariates that improved model performance and were incorporated into the final model included the effect of bodyweight on the CL/F of each drug. The estimated C

conclusionsThis study clarified the pharmacokinetic parameters and their variability for sildenafil, tadalafil, bosentan and ambrisentan using combined data from Japanese paediatric and adult patients with PAH. The results of Bayesian estimation suggest that at current clinical dosages, plasma concentrations of these drugs may be lower in paediatric than adult patients.
