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

A 71-year-old female with postoperative recurrence of lung adenocarcinoma was treated with chemotherapy plus immunotherapy (carboplatin, pemetrexed, and pembrolizumab). On day eight after the first cycle, she presented with fever and loss of appetite. Laboratory tests showed severe pancytopenia. Bone marrow biopsy revealed hypocellular marrow consistent with aplastic anemia (AA), which is considered an immune-related adverse event (irAE). Treatment with pulse glucocorticoid (GC) therapy, granulocyte colony-stimulating factor, and cyclosporine had a limited effect. On day 24, eltrombopag, a thrombopoietin receptor agonist, was started, subsequently leading to gradual hematologic recovery and discharge on day 34. IrAE-induced AA has a poor prognosis, with no established standard treatment. This case demonstrates the potential of thrombopoietin receptor agonists as a therapeutic option in GC-resistant irAE-induced AA.
