Clinical Pharmacokinetics and Pharmacodynamics of Ceftazidime-Avibactam Combination: A Model-Informed Strategy for its Clinical Development.
Review in Clinical pharmacokinetics, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 36 papers.
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
Avibactam is a non-β-lactam, β-lactamase inhibitor of the diazabicyclooctane class that covalently acylates its β-lactamase targets, encompassing extended spectrum of activities that cover serine β-lactamases but not metallo-β-lactamases. Ceftazidime and avibactam have complementary pharmacokinetic (PK) profiles. Both drugs have a half-life of approximately 2 h, making them suitable to be combined in a fixed-dose combination ratio of 4:1 (ceftazidime:avibactam). Renal clearance is the primary elimination pathway of both ceftazidime and avibactam, and dose adjustment is required in patients with moderate and severe renal impairment. Population PK models of ceftazidime and avibactam were developed separately and incorporated body weight, disease state, ethnicity, and renal function (creatinine clearance) as covariates of clearance and volume of distribution. The clinical dosing regimen of ceftazidime/avibactam combination was determined from population PK model simulations in the patient population for dosing regimens that can achieve sufficient joint probability of target attainment for ceftazidime minimum inhibitory concentration (MIC) of 8 mg/L at a fixed 4 mg/L avibactam concentration (MIC ≤ 8/4 mg/L); 8 mg/L is the breakpoint of ceftazidime in Enterobacteriaceae and Pseudomonas aeruginosa for the target pharmacodynamic indices of ceftazidime and avibactam of 50% time at which the free ceftazidime concentration is above the MIC (fT > MIC) and 50% time at which the free avibactam is above a threshold concentration of 1 mg/L (fT > C
