Delayed Breast Cancer Detection in an Asian Country (Taiwan) with Low COVID-19 Incidence.
Article in Cancer management and research, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04750018 (Influence of Co-Vid 19 Pandemic on Screening Mammography in a Single Institution), which is not on this map. Cited by 12 papers, 3 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.

Abstract
purposeTo assess whether the COVID-19 pandemic delayed breast cancer diagnosis in Taiwan, an Asian country with a low COVID-19 incidence.
methodsThe monthly volume of breast biopsies and breast cancers during the COVID-19 pandemic (during January 21 and July 31, 2020) was compared to the same period in 2019 (pre-COVID-19).
resultsTaiwan recorded a lower COVID-19 incidence rate (20.2 cases per million population) than other Asian countries. The screen-detected lesions accounted for 55% and 36% of 2019 and 2020 total biopsied lesions, respectively. Total breast biopsy, mammography-guided, and ultrasound-guided biopsies decreased by 17%, 23%, and 14%, respectively, from pre-COVID-19 to COVID-19. Monthly differences were significant in total biopsy (p=0.03), mammography-guided biopsy (p=0.04), and a benign pathology result after breast biopsy (p<0.01). Nearly 46% decline was noted in the biopsy results of non-invasive breast cancer in 2020. The number of total breast cancers and early breast cancers (stages 0 and 1) decreased by 10% and 38%, respectively, during pandemic. Individuals with early breast cancer accounted for 71% and 49% of the total diagnosed breast cancer in the pre-COVID-19 and COVID-19 periods, respectively (p<0.001).
conclusionThe pandemic significantly delayed early breast cancer detection in Taiwan despite low COVID-19 incidence. CLINICAL
