Quantifying Gamma-Interferon from CMV-Specific CD8+ T Cells Defines Protection Against Clinically Significant CMV Infection in Solid Organ Transplant Recipients: The Quanti-CMV Score.

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
The cutoff value of the commercial interferon (IFN)-γ release assay (QuantiFERON-CMV) proposed by the manufacturer is assumed to be predictive. We aimed to determine the optimal cutoff value for protection against clinically significant cytomegalovirus (CMV) infection within 30 days. We analyzed two different cohorts: adult CMV seropositive kidney transplant (KT) recipients with antithymocyte globulin (ATG) induction from the TIMOVAL study and seropositive lung transplant (LT) patients from the CYTOCOR study. The optimal cutoff value was established using Youden's index. We estimated the predictive capacity of the cutoff value through the AUROC and assessed the diagnostic accuracy of the assay at the different cutoff values. We finally evaluated clinical variables that could improve the predictive ability of the assay on a predictive score. Four hundred-four samples from 130 transplant recipients were analyzed. The optimal cutoff value was ≥2.2 IU/mL for both populations, with a positive predictive value of 99% and 99.5% (95% CI, 98-100%) for KT and LT recipients, respectively. The AUROC of the predictive score was 0.85 (95% CI, 0.73-0.97). Using the proposed cutoff value and the Quanti-CMV score may allow the individualization of preventive strategies and serve as an objective tool to support clinical decision-making.
