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

Immune checkpoint inhibitors (ICIs) are essential treatments for lung cancer, but their safety following allogeneic haematopoietic stem cell transplantation (allo-HSCT) remains unclear. We report a case of a 66-year-old man who underwent umbilical cord blood transplantation for acute lymphoblastic leukaemia and later developed lung adenocarcinoma. Pembrolizumab monotherapy was initiated, but the patient developed severe steroid-refractory immune-related pneumonitis, leading to mortality 56 days after treatment initiation. Given the scarcity of reports on ICI use in lung cancer patients with prior HSCT, this case highlights critical safety considerations.
