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

backgroundCalcineurin inhibitor (CNI) nephrotoxicity drives long-term kidney-function decline after simultaneous pancreas-kidney (SPK) and liver-kidney (LK) transplantation, but belatacept conversion, as an alternative strategy, is poorly studied in these recipients, whose non-kidney allograft rejection risk differs.

methodsWe retrospectively studied six SPK and six LK recipients converted from CNI- to belatacept-based immunosuppression and analyzed the cohorts separately alongside a narrative review of published SPK/LK conversion experiences. Outcomes were estimated glomerular filtration rate (eGFR) trajectories and slopes, donor-specific antibodies (DSA) and rejection, pancreatic, hepatic and metabolic parameters, infections, and survival, reported descriptively with exploratory estimates and 95% confidence intervals (CI).

resultsConversion occurred a median of 64 (SPK) and 89 (LK) months after transplantation, always with a transient low-dose CNI overlap (target trough 3-4 ng/ml). In SPK recipients, median eGFR rose from 45.4 to 55.5 mL/min/1.73m

conclusionsLate belatacept conversion with a transient low-dose CNI overlap was feasible in selected SPK and LK recipients and was associated with stable-to-improved kidney function without a pancreatic or hepatic safety signal. The uncontrolled design supports feasibility, not efficacy.
