Immunosuppression Withdrawal in Pediatric Liver Transplant Recipients With Posttransplant Lymphoproliferative Disorder: A Single-Center Retrospective Study.
Article in Annals of transplantation, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
BACKGROUND Posttransplant lymphoproliferative disorder (PTLD) is a serious complication following pediatric liver transplantation. Reduction of immunosuppression is a cornerstone of PTLD management; however, the feasibility and safety of complete immunosuppression withdrawal (ISW) in this setting remain unclear. MATERIAL AND METHODS We retrospectively reviewed 6 pediatric liver transplant recipients diagnosed with PTLD who subsequently underwent complete ISW at our center between 2013 and 2019. Demographic characteristics, clinical features, pathological classification, treatments, and follow-up outcomes were analyzed. RESULTS The cohort included 6 children (4 females and 2 males) who underwent liver transplantation at a median age of 8 months. PTLD subtypes included infectious mononucleosis-type (n=3), polymorphic PTLD (n=1), Burkitt lymphoma (n=1), and classical Hodgkin lymphoma-like PTLD (n=1). All patients achieved complete remission following multimodal therapy. The median interval from transplantation to initiation of ISW was 35 months. During a median follow-up of 52 months after ISW, 4 patients maintained stable graft function without biopsy-proven rejection, whereas 2 developed rejection-related complications, both of which resolved after restart of low-dose immunosuppressive therapy. No graft loss or PTLD recurrence occurred. CONCLUSIONS In carefully selected pediatric liver transplant recipients with PTLD, supervised ISW may be achieved without irreversible graft injury. However, a substantial risk of rejection remains, highlighting the importance of close clinical and histological monitoring.
