Racial comparisons of everolimus pharmacokinetics and pharmacodynamics in adult kidney transplant recipients.
Article in Therapeutic drug monitoring, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundThere is limited data analyzing the pharmacokinetic (PK) and pharmacodynamic (PD) properties of everolimus (EVR) between African Americans and Caucasians. The purpose of this study was to determine and compare the EVR PKs and concentration-associated efficacy and toxicity in African American and Caucasian adult kidney transplant recipients.
methodsThis was a retrospective PK and PD analysis of all patients who received EVR at the Medical University of South Carolina Transplant Center between 2006 and 2012.
resultsForty-three patients received EVR (22 African Americans, 21 Caucasians). Baseline demographics, immunosuppression, and immunologic risk were similar between races, except for preexisting hypertension, deceased donor type, and cold ischemic time, which were higher in African American patients. PK analysis revealed that African American patients received higher initial EVR doses (2.1 ± 0.8 versus 1.6 ± 0.6 mg/d, P = 0.036), leading to higher early EVR concentrations (EVR >6 ng/mL during the first 60 days: 36% versus 10%, P = 0.037). Efficacy analysis demonstrated similar EVR effects on acute rejection rates (9% versus 10%, P = 0.961), chronic allograft changes (18% versus 14%, P = 0.729), and renal function, with both groups having improved creatinine clearance with EVR therapy (ΔeGFR: 27 versus 12 mL·min·1.73 m). Toxicity analysis demonstrated that African American patients had a trend toward higher rates of EVR discontinuation (46% versus 19%, P = 0.065) and significantly more diarrhea/gastrointestinal intolerance (73% versus 38%, P = 0.022).
conclusionsThese results demonstrate EVR therapy is effective at preventing rejection and improving graft function in both African American and Caucasian adult renal transplant patients. Conflicting with previous mammalian target of rapamycin PK/PD analyses in African American patients, this study cohort demonstrated higher early EVR levels in the African American patients.
