Prognostic impact of pleural effusion in EGFR-mutant non-small cell lung cancer patients without brain metastasis.
Article in Thoracic cancer, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 2 of them syntheses that pooled 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.
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
backgroundIn epidermal growth factor receptor (EGFR)-mutant non-small cell lung cancer (NSCLC), brain metastasis is known as a poor prognosis factor. However, prognostic factors in the patients without brain metastasis remain unclear. In this study, we aimed to clarify the differences between metastatic site and prognosis in common EGFR-mutant NSCLC patients without brain metastasis.
methodsChemotherapy-naïve, advanced EGFR-mutant NSCLC patients without brain metastasis diagnosed between January 2010 and March 2016 were enrolled. We evaluated prognosis according to the presence or absence of bone metastases, liver metastasis, and pleural effusion.
resultsA total of 50 EGFR-mutant NSCLC patients without brain metastasis were enrolled. The median progression-free survival and overall survival were significantly shorter in patients with pleural effusion than in those patients without (progression-free survival 7.0 months, 95% confidence interval [CI] 3.7-13.0 vs. 13.0 months, 95% CI 9.1-21.7, hazard ratio [HR] 2.29, 95% CI 1.11-4.73, P = 0.020; overall survival 19.5 months, 95% CI 5.7-28.8 vs. 55.3 months, 95% CI 24.0-not evaluable, HR 3.00, 95% CI 1.35-6.68, P = 0.005). Pleural effusion was an independent factor of poor prognosis for progression-free survival (HR 3.44, 95% CI 1.50-7.88, P = 0.003) and overall survival (HR 2.34, 95% CI 1.00-5.44, P = 0.049).
conclusionPleural effusion might be a poor prognosis factor for advanced EGFR-mutant NSCLC patients without brain metastasis treated with first-generation EGFR-tyrosine kinase inhibitors. Further precision medicine according to the metastatic site is required.
