Impact of the COVID-19 Pandemic on Diagnosis and Multidisciplinary Treatment of NSCLC in Ontario, Canada.

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
Introduction: The coronavirus disease 2019 pandemic disrupted cancer care delivery globally, with many jurisdictions reporting reductions in lung cancer diagnoses and delays in treatment. In Ontario, Canada, both institutional and provincial data have reported mixed trends in NSCLC presentation and care. This study aimed to assess the short-term impact of the coronavirus disease 2019 pandemic on NSCLC diagnoses and treatment pathways across Ontario using population-level data from Cancer Care Ontario administrative health databases. Methods: We conducted a retrospective cohort study of patients diagnosed with NSCLC in Ontario between January 1, 2019 and December 31, 2020. The cohort was created using relevant diagnostic codes and linked provincial databases to evaluate diagnostic trends and access to surgical, medical, and radiation oncology services. Statistical analyses included Poisson regression to assess changes in diagnosis rates and multivariable linear regressions to evaluate wait times, adjusting for age, sex, income quintile, and geographic region. Results: A total of 13,407 NSCLC cases were identified. There was a 6% overall decline in diagnoses in 2020, with a 31% drop during quarter 2 (April-June 2020). The mean wait times for surgical consultation and treatment and also medical and radiation oncology consults improved or remained stable. No delays were found in systemic therapy initiation. Multivariable analyses confirmed these findings. Conclusions: NSCLC care delivery in Ontario remained stable during the early pandemic period. Declines in diagnosis warrant further investigation using longer-term data. Real-time data systems are essential for future pandemic preparedness and response.
