Impact of EGFR Mutations on Survival and Clinical Response in Non-Small Cell Lung Cancer in a Tertiary Care Hospital.
Article in Clinical and translational science, 2026. 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
Lung cancer continues to be the leading cause of morbidity and mortality associated with malignancies. Identifying prognostic factors is vital for improving survival outcomes. This study assessed the impact of clinical, demographic, and genetic factors on overall survival (OS) and progression-free survival (PFS) in patients with non-small cell lung cancer (NSCLC). A prospective cohort of 70 NSCLC patients was analyzed. Demographic and clinical data, including epidermal growth factor receptor (EGFR) mutation status and clinical response by RECIST 1.1 criteria, were assessed. Survival outcomes were estimated using the Kaplan-Meier method with log-rank test. The median PFS and OS were 15 and 24 months, respectively. EGFR-positive patients showed significantly longer survival than EGFR-negative patients (PFS: 17 vs. 11 months, OS: not reached [NA] vs. 24 months). Brain metastases indicated poor OS (OS: 15 months vs. NA) but did not affect PFS. Patients with a partial response after one year exhibited improved overall survival (24-month OS probability of 77.8%). EGFR mutation status, brain metastases, and clinical response are key predictors of survival in NSCLC patients. Integrating genetic screening, timely management of brain metastases, and early assessment may enhance personalized treatment and improve prognosis.
