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

aimsWe aimed to explore the prognostic role of circulating DNA-related markers to improve clinical decision-making in patients with lung malignancies.

methodsA systematic search was performed on PubMed, Scopus, and Web of Science.

resultsAbout 133 articles were included, comprising 5750 EGFR-positive, 1583 ALK-positive, and 9657 patients without specified genetic groups. Circulating tumor DNA (ctDNA) response was a significant prognostic marker associated with improved overall survival (OS) (HR = 0.36 [0.27, 0.47], I2 = 0%) and progression-free survival (PFS) (HR = 0.31 [0.18, 0.55], I2 = 67.33%) in advanced non-small cell lung cancer (NSCLC). Meta-analysis of tumor mutational burden (TMB) in the same group demonstrated trends toward poorer survival outcomes for higher TMB -pooled HR of 1.63 (95%-CI: 0.92, 2.88, I2 = 71.23%) for OS and 1.09 (95%-CI: 0.63, 1.89, I2 = 86.66%) for PFS. Finally, meta-analysis in advanced EGFR-positive NSCLC implicated significant prognostic effect of EGFR response positivity on OS and PFS -pooled HR of 0.39 and 0.27, respectively.

conclusionCirculating DNA markers entailed valuable information in patient prognostication and depicting treatment efficacies in lung cancer. Further studies are needed to decipher more robust criteria for the presently accepted markers - namely ctDNA and EGFR response measures. Additionally, there are several markers - i.e. TMB - that have more exploratory clinical benefits.
