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

backgroundTherapeutic drug monitoring (TDM) may optimize dosing of mycophenolate mofetil (MMF) in patients with nephrotic syndrome, but it is not routinely implemented. When performed, TDM typically relies on total mycophenolic acid (MPA) concentrations, although only unbound MPA is pharmacologically active. This study aimed to develop a population pharmacokinetic (PK) model characterizing the PK and pharmacodynamics (PD) of total and unbound MPA in plasma and saliva of paediatric nephrotic syndrome patients following oral MMF.

methodsPK/PD data from 62 children (47 full and 21 limited sampling curves) were analysed using nonlinear mixed-effects modelling.

resultsA two-compartment model with first-order absorption best describes unbound MPA PK. Protein binding was captured using a nonlinear saturable binding equation. The final population PK parameter estimates (for unbound MPA) were absorption rate constant (k

conclusionThe developed model provides a foundation for model-informed precision dosing of MMF in children with nephrotic syndrome.
