Circulating Tumor DNA Testing Overcomes Limitations of Comprehensive Genomic Profiling from Tumor Tissue.
Article in Case reports in oncology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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.
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
"Liquid biopsy" is an established technique for examining circulating tumor DNA (ctDNA) from a routine blood draw and detecting actionable biomarkers. Nonetheless, ctDNA testing is rarely utilized for patients with newly diagnosed metastatic colorectal cancer (CRC). We report a case in which ctDNA testing uncovered an actionable biomarker that was not detected by comprehensive genomic profiling of tumor tissue. An 81-year-old woman with a remote history of non-Hodgkin's lymphoma presented with primary masses in the ascending colon and sigmoid colon. The ascending colon and sigmoid colon tumors were classified as microsatellite stable (MSS) and mismatch repair proficient (pMMR), and both ctDNA and tissue next-generation sequencing (NGS) from the ascending colon mass were ordered. Because tissue NGS results indicated that the ascending colon tumor was MSS, palliative 5-fluorouracil, leucovorin, and oxaliplatin (FOLFOX) chemotherapy was started. However, the ctDNA NGS results that arrived after the start of FOLFOX found high microsatellite instability (MSI-H) and mismatch repair deficiency (dMMR) disease with a serine/threonine-protein kinase B-Raf (
