Clinical Significance of Time-to-Surgery and COVID-19 Pandemic in Surgically Treated Non-Small Cell Lung Cancer.
Article in Thoracic cancer, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectivesTimely discovery and adequate patient management are crucial in non-small cell lung cancer (NSCLC) since long-term survival is only achievable in early-stage disease. In our study, we aimed to elucidate the effects of time to surgery on survival and to assess the impact of the COVID-19 pandemic on elapsed time until surgery.
methodsIn total, 2536 Caucasian NSCLC patients who underwent curative-intent lung resection surgery were included in this study. 1 month, 2 months, 77 days, and 91.06 days between CT-based diagnosis and surgery were evaluated as possible cut-off values for worse outcome. Survival curves were estimated by Kaplan-Meier plots, and the differences between groups were compared using the log-rank test. Multivariate analysis was performed using a Cox regression model.
resultsPatients with time-to-surgery ≥ 2 months had significantly impaired overall survival (OS) (vs. those with < 2 months; p = 0.002). In our multivariate model, time-to-surgery (p = 0.011), age (p = 0.02), diabetes mellitus (p = 0.02), disease stage (p = 0.0001) and vascular invasion (p < 0.001) all had a significant impact on OS. Importantly, during the COVID-19 pandemic, the elapsed time between diagnosis and surgery increased with a median of 12 days, resulting in a significant delay in time-to-surgery compared to the pre-pandemic period (p < 0.001). Post hoc tests showed, however, that there were no significant differences in time-to-surgery concerning the major waves of COVID-19 infections.
conclusionsTime-to-surgery is an independent predictor of long-term survival in surgically treated NSCLC. In general, the COVID-19 pandemic caused a significant delay in the elapsed time until surgery, but the specific COVID-19 waves had no significant impact on time-to-surgery.
