1 · What the graph read from 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.

2 · The registry

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

Background: Acute cellular rejection (ACR) is a common complication following heart transplantation (HTx). This study examined the association between tacrolimus whole-blood concentrations and endomyocardial biopsy (EMB)-proven ACR in adult HTx recipients. Methods: We conducted a retrospective analysis of 41 adult HTx recipients enrolled in the HEARTBiT study at St. Paul's Hospital (Vancouver, Canada) between August 2018 and February 2020. A total of 315 EMB visits were analyzed and matched with tacrolimus whole-blood trough concentrations measured within ±1 day using liquid chromatography-tandem mass spectrometry. Patients were stratified into 2 post-transplant intervals: 0 to 90 days and 91 to 180 days, based on BC Clinical Guidelines for Transplant Medications for target tacrolimus levels. Results: During the first 90 days post transplant, tacrolimus concentrations were significantly lower in 2R rejection episodes compared to both 0R ( Conclusions: Lower tacrolimus concentrations during moderate ACR episodes were not attributable to underdosing or clinical confounders, suggesting the role of altered pharmacokinetics or patient-specific factors. Taken together, our results emphasize the clinical relevance of tailoring tacrolimus targets to individual pharmacokinetics, especially in early-phase post-transplant care.
