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

Chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) is the most prevalent leukemia in adults which typically follows an indolent clinical course. However, it has the potential to transform into more aggressive categories, including accelerated CLL or diffuse large B-cell lymphoma (DLBCL), a phenomenon known as Richter transformation. Bruton tyrosine kinase inhibidors (BTKI), such as ibrutinib and zanubrutinib, represent a cornerstone of CLL/SLL treatment by inhibiting B-cell receptor signaling. Temporary discontinuation of these agents are common due to surgical procedures or infections which has been associated with rapid disease progression, producing a pseudo-Richter transformation (P-RT) in tissues. We present a case with CLL/SLL who experienced clinical deterioration following ibrutinib withdrawal, resulting in an explosive disease flare and splenic rupture. The patient improved after BTKI reintroduction, and a P-RT was diagnosed. Nine similar patients were found through PubMed search, and we describe their clinicopathological characteristics.
