Impact of HDV infection on post-transplant outcomes in patients transplanted for HBV-related liver disease: results from a multicenter cohort study in Southern Italy.

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
aimsPatients with HBV and HBV/HDV infection were compared in terms of clinical outcomes after liver transplantation in a long-term follow-up.
methodsIn a multicenter retrospective study, the patients, who had received liver transplants for HBV chronic liver disease, were enrolled in a long-term follow-up (1-20 years). The primary outcome was overall survival, the secondary outcome occurrence of clinical events.
resultsA total of 257 patients were enrolled, 95 with HBV (HBV group) and 162 with HBV/HDV (HBV/HDV group) infection. Overall, 31 patients died in the follow-up, most frequently due to extrahepatic events. Overall mortality was similar between the two groups (15.8% in HBV vs 9.9% in HBV/HDV group), while deaths from hepatic events were more frequent in the first group (7.4 vs. 1.2%, p = 0.014). In multivariable logistic regression analysis only a history of chronic kidney disease (CKD) at the time of transplantation emerged as independent factor associated with death (OR 7.027, 95% CI 2.068-23.876; p = 0.002). Overall, 84 patients experienced at least one clinical event, mainly onset of renal failure (57 cases), cancer (32) and hepatic clinical (19). Compared with HBV/HDV group, clinical events occurred more frequently in HBV group (44.2 vs. 25.9%; p = 0.003), both hepatic and extrahepatic (11.6 vs. 4.9%, p = 0.050; 35.8 vs. 23.5%, p = 0.034, respectively). In multivariable logistic regression analysis, HBV group (OR 2.243, 95% CI 1.172-4.293; p = 0.015) and CKD at the time of transplantation were associated to the occurrence of clinical events (OR 8.890, 95% CI 2.373-33.306; p = 0.001).
conclusionsIn this long-term follow-up study, HDV infection was not associated to a worsen post-transplant outcomes, while chronic kidney disease at transplantation emerged as the strongest predictor of mortality and clinical events.
