Baseline retinoblastoma transcriptional corepressor 1 (Rb1) functional inactivation is a pre-requisite but not sufficient for small-cell histological transformation in epidermal growth factor receptor (EGFR) mutant lung adenocarcinomas post-tyrosine kinase inhibitor therapy.

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

Small-cell transformation is an uncommon mechanism of tyrosine receptor kinase inhibitor (TKI) resistance in epidermal growth factor receptor (EGFR)-mutant lung adenocarcinomas. This study aims to assess the dynamic changes in the molecular landscape and Rb1 functional status in EGFR-mutant lung adenocarcinomas transforming to small-cell carcinomas post-treatment with EGFR-TKIs. This is an ambispective study (2019-2023) wherein the baseline and post-TKI biopsies of EGFR-mutant lung adenocarcinomas with small-cell transformation were subject to Rb1 immunohistochemistry and 72-gene targeted panel next-generation sequencing. Rb1-deficiency was defined as Rb1 protein loss or Rb1
