Prognostic role of epidermal growth factor receptor mutation status in patients with de novo lung adenocarcinoma.
Article in Translational cancer research, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundTo explore the relationship between the status of epidermal growth factor receptor (EGFR) and overall survival (OS) in de novo lung adenocarcinoma.
methodsWe retrospectively analyzed 291 lung adenocarcinoma subjects with exact EGFR status. The cases were divided into a mutant-type group (124 patients) and wild-type group (167 patients) according to the status of EGFR. The general information, OS, and possible risk factors influencing the OS were also evaluated.
resultsThe EGFR mutation rate was 42.6% (124/291 patients), and there were statistically significant differences in gender, smoking history, and OS (P<0.05), but no significant difference in diagnosed age, alcohol history, TNM stage, clinical stage, and immunohistochemistry between the two groups (P>0.05). The most common subtypes of EGFR mutations were exon 19 and exon 21. The median OS of the total population was 30.20 months [95% confidence interval (CI): 25.94-34.46 months] and the OS in the mutant-type group was better than in the wild-type group (P<0.001). Cox regression demonstrated that N stage, M stage, and EGFR status were the risk factors for OS in de novo lung adenocarcinoma patients (P<0.001), and the relative risk were 1.398 (95% CI: 1.214-1.609), 2.427 (95% CI: 1.780-3.310), and 2.030 (95% CI: 1.528-2.699), respectively.
conclusionsThe OS of EGFR mutant individuals was better than that of wild-type patients in de novo lung adenocarcinoma patients. EGFR mutation may be a useful prognostic indicator in lung adenocarcinoma.
