The number of obstructive colorectal cancers in Japan has increased during the COVID-19 pandemic: A retrospective single-center cohort study.
Article in Annals of medicine and surgery (2012), 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 26 papers, 2 of them syntheses 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
backgroundThe global pandemic of COVID-19 has changed cancer treatment environments. In Japan, cancer screenings were halted and the numbers of endoscopies and surgeries were restricted in some hospitals based on the state of emergency declared. Herein, we investigated the impact of the COVID-19 pandemic on the characteristics of colorectal cancer (CRC) patients in facilities that are on the frontline of both COVID-19 and cancer treatments. PATIENTS AND
methodsWe retrospectively analyzed the cases of all of the CRC patients (n = 123) who underwent surgery at our regional cancer treatment center and tertiary emergency hospital in Japan during a 120-day period ranging from before to after the state of emergency declaration. CRC patients during the corresponding period in the previous year were also examined.
resultsAlthough the number of CRC patients did not show a significant change related to the pandemic, the incidence of obstructive CRCs significantly increased after the pandemic's start. The numbers of outpatients and colonoscopies both decreased, which could have resulted in the decrease of CRC patients detected by cancer screening during the pandemic. The numbers of symptomatic CRC patients and emergency admissions both increased significantly during the pandemic.
conclusionOur findings indicate the possibility that the discovery of CRCs in patients could be delayed due to the halt in screenings caused by the COVID-19 pandemic, resulting in the increase of obstructive CRCs. These results highlight the importance of cancer screening and suggest that the screening system for cancers should be reorganized before future pandemics.
