Delay in breast cancer diagnosis and its clinical consequences during the coronavirus disease pandemic.
Article in Journal of surgical oncology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 29 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
objectiveAt the end of 1 year of the coronavirus disease (COVID-19) pandemic, we aimed to reveal the changes in breast cancer cases in the context of cause and effect based on the data of surgically treated patients in our institution. PATIENTS AND
methodsPatients with breast cancer were divided into two groups. Group 1 consisted of patients who were operated in the year before the COVID-19 pandemic, and Group 2 consisted of patients who were operated within the first year of the pandemic. Tumor size, axillary lymph node positivity, distant organ metastasis status, neoadjuvant chemotherapy, and type of surgery performed were compared between the two groups.
resultsThe tumor size, axillary lymph node positivity, and neoadjuvant chemotherapy were higher in Group 2 than in Group 1 (p = .005, p = .012, p = .042, respectively). In addition, the number of breast-conserving surgery + sentinel lymph node biopsy were lower, while the number of mastectomy and modified radical mastectomy were higher in Group 2 than in Group 1 (p = .034).
conclusionPatients presented with larger breast tumors and increased axillary involvement during the pandemic. Moreover, distant organ metastases may increase in the future.
