Continued implications of the COVID-19 pandemic environment on non-small cell lung cancer characteristics and treatment in the United States.
Article in Journal of thoracic disease, 2025. 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
Background: Given the continued disruption of the coronavirus disease 2019 (COVID-19) pandemic throughout 2021, we aimed to assess for continued implications of the altered healthcare landscape on non-small cell lung cancer (NSCLC) presentation and treatment in the second year of the pandemic. Methods: This was a retrospective cohort study using the United States National Cancer Database (2019-2021). Demographic, cancer-related, and treatment variables were compared between patients diagnosed in the pre-pandemic year [2019], pandemic-year-one [2020], and pandemic-year-two [2021]. Multivariate logistic regression was performed to control for the impact of demographics on oncologic variables, and then for the impact of oncologic variables on treatment modalities and outcomes. Results: Of 376,193 NSCLC cases, 135,649 (36.1%) were pre-pandemic, 119,338 (31.7%) were pandemic-year-one, and 121,206 (32.2%) were pandemic-year-two. Compared to the pre-pandemic year, patients diagnosed in pandemic-year-two had risk-adjusted increases in clinical T stage [odds ratio (OR) =1.017; 95% confidence-interval (CI): 1.003-1.031], N stage (OR =1.048; 95% CI: 1.033-1.063), M stage (OR =1.044; 95% CI: 1.028-1.060), and overall stage (OR =1.038; 95% CI: 1.023-1.052). Additionally, compared to the pre-pandemic year, patients diagnosed in pandemic-year-two continue to see risk-adjusted increases in time from diagnosis to staging (OR =1.044; 95% CI: 1.017-1.072), to first treatment (OR =1.143; 95% CI: 1.133-1.154), to surgery (OR =1.117; 95% CI: 1.093-1.141) and to systemic therapy (OR =1.021; 95% CI: 1.924-1.039). Conclusions: Compared to the pre-pandemic year, patients diagnosed with NSCLC in the United States during pandemic-year-two continue to present at later clinical stage and experience delays to treatment. The oncologic and treatment characteristics of NSCLC have not returned to pre-pandemic baseline in the United States, possibly due to compounding delays to diagnosis and treatment and a growing back log of cases.
