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

This study aimed to characterize the pharmacokinetics of tobramycin administered one, two, or three times daily and to develop an optimal dosing scheme for children with cystic fibrosis. Therapeutic drug monitoring data were obtained from children hospitalized at three academic medical centres from 2006 to 2012. Population pharmacokinetic models were constructed using NONMEM 7.2. Model-based simulations were performed in Matlab R2012b to identify optimal dosing regimens using pharmacodynamic targets. The pharmacokinetic analysis involved 257 patients with a median age of 8.1 years (range 0.1-18.8). Clearance was estimated as 5.59 L/h and the volume of distribution was 18.90 L. Mean (±SD) maximum serum concentrations were highest among patients dosed once per day (24.1 ± 8.9 μg/mL) and were lower among patients dosed two and three times per day (11.2 ± 1.4 and 8.1 ± 2.4 μg/mL, respectively). Simulations revealed that once daily dosing was the only effective regimen for a Pseudomonas aeruginosa MIC of 1.5 μg/mL and none of the tested regimens reliably achieved the pharmacodynamic target for MICs ≥2 μg/mL. Once daily dosing resulted in higher maximum serum concentrations when compared to multiple-daily dosing. In simulations, once daily dosing was the only regimen to achieve the pharmacodynamic target for all subjects with MICs <2 μg/mL.
