Impact of Attaining an Aggressive Pharmacokinetic-Pharmacodynamic Target on the Clinical Efficacy of Continuous Infusion β-Lactam Therapy for Early Posttransplant Gram-Negative Infections in Critically Ill Orthotopic Liver Transplant Recipients: An Interim Analysis of a 3-Year Prospective, Observational Study.
Observational study in The Journal of infectious diseases, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundTo assess the impact of attaining aggressive β-lactam (BL) pharmacokinetic-pharmacodynamic (PK/PD) targets on clinical efficacy in critically ill orthotopic liver transplant (OLT) recipients with documented early gram-negative infections.
methodsThe study prospectively enrolled OLT recipients admitted to the posttransplant intensive care unit between June 2021 and May 2024; they had documented gram-negative infections treated with targeted therapy continuous infusion (CI) BLs and underwent therapeutic drug monitoring (TDM)-guided BL dosing adjustment within the first 72 hours. Aggressive PK/PD target attainment was measured. Multivariate logistic regression analyses were performed to test independent variables associated with 30-day resistance occurrence.
resultsFifty critically ill OLT recipients were treated with CI BL in monotherapy (n = 34) or combination (n = 16) therapy for documented gram-negative infections No significant difference in clinical/microbiological outcome emerged between monotherapy and combination therapy. In 4 patients (8.0%), resistance developed within 30 days. At multivariate analysis, failure in attaining an aggressive BL PK/PD target emerged as the only independent predictor of 30-day resistance development (odds ratio, 14.33 [95% confidence interval, 1.46-140.53]; P = .02).
conclusionsAttaining an aggressive PK/PD target with CI BLs in critically ill OLT recipients with documented gram-negative infections could represent an effective strategy for minimizing resistance occurrence to the selected BL.
