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

Neutropenia, a rare immune-related adverse event, affects patients receiving treatment with immune checkpoint inhibitors (ICIs). We herein report a case of pembrolizumab-induced agranulocytosis. An 83-year-old man was diagnosed with advanced-stage lung carcinoma concomitant with splenomegaly complicated by hypersplenism, causing pancytopenia. To avoid the risk of bone marrow suppression due to cytotoxic chemotherapy, pembrolizumab monotherapy was chosen. However, the patient developed agranulocytosis despite the resolution of pancytopenia through splenectomy performed after the fourth pembrolizumab cycle. Neutrophil counts improved after steroid treatment but not after granulocyte colony-stimulating factor treatment. This case demonstrated that neutropenia can sometimes develop abruptly after several ICI therapy cycles.
