Impact of COVID-19 Pandemic on the Clinical and Pathologic Characteristics of Colorectal Cancer: A Retrospective Multicenter Study in South Korea.
Article in Cancer management and research, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled it.
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
Purpose: The COVID-19 pandemic has influenced various aspects of colorectal cancer (CRC) patient care, including diagnosis, treatment, and outcomes. This study assesses the pandemic's impact on CRC patients. Methods: We performed a retrospective analysis of medical records for CRC patients who underwent surgery at five hospitals affiliated with Hallym University from January 2017 to December 2022. Patients were divided into two groups: the pre-COVID group (2017-2019) and the COVID group (2020-2022). Results: Among 2038 patients, 987 (48.4%) were in the pre-COVID group, and 1051 (51.6%) were in the COVID group. The COVID group had more patients with two or more comorbidities (P < 0.001) and a higher incidence of rectal cancer (P = 0.010). While the rates of laparoscopic surgeries were similar, the COVID group had increased emergency surgeries (P = 0.005) and diversion procedures (P = 0.002). Additionally, the COVID group faced more overall complications (P < 0.001) and severe complications (Grade III-V, P = 0.004). There was a rise in lymphovascular invasion (P < 0.001) and T4 stage tumors (P < 0.001) within the COVID group. Despite these differences, both groups had similar 2-year overall survival rates (P = 0.409). Conclusion: Although patients treated during the COVID period experienced more frequent stoma formation, complications, and adverse prognostic factors, there were no differences in short-term oncologic outcomes, which was likely due to the follow-up period being insufficient to detect differences in OS.
