The pharmacokinetics of ceftriaxone based on population pharmacokinetics and the prediction of efficacy in Japanese adults.
Article in European journal of drug metabolism and pharmacokinetics. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectiveBy using a population pharmacokinetic analysis method, we predicted the efficacy of Ceftriaxone (CTRX) based on the pharmacokinetics of CTRX in Japanese adults and the sensitivity of infective organisms to CTRX in 2004. In addition, we clarified the difference in efficacy between once-a-day administration and twice-a-day administration.
methodsThe population pharmacokinetic analysis was based on the serum concentrations of CTRX already published by NONMEM. The possible effect of body weight and age on the pharmacokinetics of CTRX was examined using a model which incorporated the change of a specific protein-binding ratio of CTRX. A Monte Carlo simulation was conducted based on the population pharmacokinetic parameters obtained by this analysis, and thereby the time above MIC (TAM) was determined from the MIC values of CTRX administered once at 0.5, 1, and 2 g and twice at 1 g. The efficacy ratio was predicted from the TAM thus obtained.
resultsBecause the time course of serum concentration of CTRX in adult subjects was fitted to a 2-compartment model and both body weight and age were not incorporated as the covariate, the dosing method by which a fixed amount of CTRX is administered to patients has been thought to be adequate. Based on the efficacy ratio estimated from the MIC of CTRX, we have predicted that the once-a-day administration of CTRX even at 0.5g is effective on various infecting organisms.
