Decreased numbers of gastric, colorectal, lung, and breast cancer surgeries performed in 17 cancer-designated hospitals in Gunma Prefecture of Japan during the COVID-19 pandemic.
Article in Surgery today, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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
purposeThis study aims to clarify the influence of the COVID-19 pandemic on cancer surgery in Gunma Prefecture.
methodsA total of 9839 cases (1406 gastric cancer, 3569 colorectal cancer, 1614 lung cancer, and 3250 breast cancer) from 17 hospitals in Gunma Prefecture were investigated. We compared the number of surgical cases, proportion of cases found by screening, and cStage at the time of the first visit by month in 2020 and 2021 with those in 2019.
resultsThe rate of decline in cancer surgery was 8.9% in 2020 compared with 2019 (p = 0.0052). Compared with the same month of 2019, in some months of 2020 and 2021, significant decreases were observed in the number of surgeries for gastric and colorectal cancer, the percentage of surgical cases detected by screening in all four cancers, and the proportion of cancers with a relatively early cStage in gastric and breast cancer.
conclusionsThe number of surgical cases of the four cancer types detected by cancer screening decreased in Gunma Prefecture owing to the influence of the COVID-19 pandemic. Furthermore, for some cancer types, the number of operations performed in patients with early-stage cancer is also decreased.
