The Effects of the COVID-19 Pandemic on Mastectomy Outcomes for Breast Cancer.
Article in Clinical breast cancer, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundSingle center studies have shown that during the Coronavirus Disease 2019 (COVID-19) pandemic, many patients had surgical procedures postponed or modified. We studied how the pandemic affected the clinical outcomes of breast cancer patients who underwent mastectomies in 2020.
methodsUsing the American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) database, we compared clinical variables of 31,123 and 28,680 breast cancer patients who underwent a mastectomy in 2019 and 2020, respectively. Data from 2019 served as the control, and data from 2020 represented the COVID-19 cohort.
resultsFewer surgeries of all kinds were performed in the COVID-19 year than in the control (902,968 vs. 1,076,411). The proportion of mastectomies performed in the COVID-19 cohort was greater than in the control year (3.18% vs. 2.89%, <0.001). More patients presented with ASA level 3 in the COVID-19 year vs. the control (P < .002). Additionally, the proportion of patients with disseminated cancer was lower during the COVID-19 year (P < .001). Average hospital length of stay (P < .001) and time from operation to discharge were shorter in the COVID vs. control cohort (P < .001). Fewer unplanned readmissions were seen in the COVID year (P < .004).
conclusionThe ongoing surgical services and mastectomies for breast cancer during the pandemic produced similar clinical outcomes to those seen in 2019. Prioritization of resources for sicker patients and the use of alternative interventions produced similar results for breast cancer patients who underwent a mastectomy in 2020.
