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

backgroundBrain metastases (BMs) are a common and fatal consequence in patients with advanced malignancies. Mutations happening in the epidermal growth factor receptor (EGFR) are associated with an elevated risk BMs, occurring in approximately 20-40% of patients. This study evaluates the safety and efficacy of different radiotherapy (RT) modalities in patients with EGFR-mutant lung cancer brain metastases.

methodThis study was conducted according to the PRISMA guideline. A comprehensive search was conducted on PubMed, Embase, Web of Science, and Scopus, until 13 March 2024. Stata v.17 was used for statistical analysis.

resultA total of 57 studies involving 4614 patients were analyzed, with a female predominance of 59.55% and a mean age of 50-70 years. The 6-month overall survival (OS) rate was 94% [95% CI 91-96%], 81% [95% CI 78- 84%] at 1-year, 55% [95% CI 50-60%] at 2-year, 37% [95% CI 32-42%] at 3-year, decreasing to 21% [95% CI 16-26%] at 5 years. Progression-free survival (PFS) rates were 84% [95% CI 79-89%] at 6 months and 20% [95% CI 14-26%] at 3 years. Meta-regression analysis indicated that a higher number of metastases, Karnofsky performance status below 80, and an ECOG score over one were significantly linked to OS outcomes.

conclusionRT significantly improves survival outcomes in patients with EGFR-mutant brain metastases. However, the combination of RT with targeted therapies, such as tyrosine kinase inhibitors (TKIs), appears to offer more favorable outcomes.
