The Impact of the COVID-19 Pandemic on Breast Cancer Patients.
Article in European journal of breast health, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 24 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
objectiveThe coronavirus disease-2019 (COVID-19) pandemic causes delays in the diagnosis and treatment of cancer patients due to fear of contagion and lockdown. This study aims to investigate the effects of the COVID-19 pandemic on breast cancer patients treated in our breast center. MATERIALS AND
methodsPatients who applied to our clinic with the diagnosis of invasive breast cancer in March 2020 and March 2021 (Study Group) when the COVID-19 pandemic was observed, and in March 2019 and March 2020 before the COVID-19 pandemic (Control Group) were compared in terms of demographic, clinical and pathological characteristics. Statistical analyses were performed using the SPSS software version 21.
resultsThere were 176 (46%) patients in the study and 206 (54%) patients in the control group. Almost a 15% reduction was detected in patients admitted during the COVID-19 pandemic. The rate of pre-menopausal patients and patient-related delay time (PRDT) were significantly higher in SG (57.7% vs. %45, p=0.013, 2.58 vs. 1.82-month, p=0.001, respectively). There was a larger tumor size and more metastatic lymph nodes after NAC in the SG, but the differences were not significant. There was no difference regarding breast cancer stages and molecular subtypes between the two groups, but there was significantly more de novo stage IV breast cancer in the SG (p=0.009). The incidence of neo-adjuvant chemotherapy and type of surgical therapy was similar between the two groups.
conclusionCOVID-19 pandemic caused a decrease in the number of patients who applied to our clinic and increased patient-related delay time due to fear of transmission and lockdown. The rate of de novo stage IV breast cancer was also significantly increased.
