Impact of the COVID-19 pandemic on cancer recurrence rates in patients with ovarian cancer.
Article in Gynecologic oncology reports, 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
The coronavirus diseases 2019 (COVID-19) pandemic was associated with disruption of oncology care and increased utilization of telehealth. However, the impact of the pandemic on cancer outcomes is under-studied. We evaluated the impact of the COVID-19 pandemic on recurrence rates in ovarian cancer patients in a retrospective cohort study. Women (age ≥ 18 years) diagnosed with stage I-IV epithelial ovarian cancer between 01/01/2017-06/30/2021 at Kaiser Permanente Southern California who received chemotherapy and/or surgery; and achieved complete remission following first-line treatment were included. The pre-pandemic and pandemic periods were defined based on the date of implementation of stay-at-home order in California (03/04/2020). Chart reviews were conducted to determine recurrence within 12 months of remission by physician notes, imaging findings, or CA125 levels. A total of 548 patients were included; 73.4 % and 26.6 % patients were diagnosed during the pre-pandemic and pandemic periods, respectively. About a quarter of the patients had cancer recurrence within 12 months of remission; 25.6 % and 19.2 % of patients diagnosed in the pre-pandemic and pandemic periods had recurrence, respectively (p-value = 0.12). Patients diagnosed during the pandemic were 35 % less likely to have recurrence than those in the pre-pandemic period, after adjusting for age, race/ethnicity, cancer stage, and time to treatment. Additionally adjusting for poly-ADP ribose polymerase (PARP) inhibitors in patients with stage II-IV cancer led to similar findings. In conclusion, ovarian cancer patients diagnosed and treated during the COVID-19 pandemic at KPSC did not have a higher recurrence rate than patients in the pre-pandemic period, despite changes in management approach.
