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.

Abstract

BACKGROUND In adult liver transplant patients, the use of prolonged-release tacrolimus may have treatment adherence benefits over the immediate-release formulation. The aim of this study was to characterise real-world practice data on conversion of liver transplant recipients from immediate- to prolonged-release tacrolimus in France. MATERIAL AND METHODS A prospective, observational study (NCT02143479) was conducted in 18 transplant centers in France between June 2014 and March 2016. Liver transplant recipients (n=398) included patients who changed from immediate-release to prolonged-release tacrolimus within the first three months (early conversion group) (n=205) or between three and 12 months after transplantation (late conversion group) (n=184). Clinical data were collected at an initial baseline outpatient visit and six-month and 12-month follow-up visits. Endpoints included the dose conversion ratio from immediate-release to prolonged-release tacrolimus, number of and reasons for additional visits due to conversion, safety, and tolerability. RESULTS Baseline clinical and demographic characteristics were similar between the two cohorts. The mean ±SD ratio of conversion of tacrolimus dose was 1.04±0.28; 1.01±0.28 (early) and 1.08±0.28 (late) (p=0.0247). The mean ±SD time from conversion to the first tacrolimus trough blood concentration was 30.8±42.8 days; 24.8±45.4 days (early) and 37.5±38.7 days (late). Only one patient required an additional visit due to conversion. Reasons for conversion included the physician's preference (56.3%), center practice (38.6%), and the dosing frequency (36.0%). Conversion was associated with a low rate of graft rejection, and no new safety issues were reported. CONCLUSIONS Conversion of liver transplant recipients from immediate-release to prolonged-release tacrolimus within three to 12 months of transplantation was easy to manage and associated with favorable clinical outcomes and safety profiles.
