Association of Surgeon Volume with Adherence to American Society of Breast Surgeons Surgical Quality Measures.
Article in Annals of surgical oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundSurgical volumes have long been correlated with outcomes, but their relationship to quality measures (QMs) remains unclear. This study aimed to examine the association between surgeon volumes and American Society of Breast Surgeons QM performance.
methodsThe study analyzed 635,252 women in the National Cancer Database 18 years old or older with stage I, II, or III breast cancer who underwent surgery between 1 January 2018 and 31 December 2022. Surgeon volume was calculated as tertiles using National Provider Identifiers. Quality measures included treatment timeliness, axillary management, and multidisciplinary care. Adjusted multilevel logistic models, with hospital as a random effect, were used to investigate associations of volume with QM performance.
resultsLow-volume (LV), average-volume (AV), and high-volume (HV) surgeons annually performed a median of 33 (interquartile range [IQR], 17-48), 98 (IQR, 80-112), and 169 (IQR, 147-202) breast cancer surgeries, respectively. Low-volume surgeons cared for a higher proportion of older, non-white, and non-metropolitan patients and were more likely to provide timely surgery (odds ratio [OR], 1.12; 95 % confidence interval [CI], 1.09-1.14), but less likely to adhere to adjuvant radiotherapy (odds ratio [OR], 0.81; 95 % confidence interval [CI], 0.77-0.85), appropriate axillary management (OR, 0.65; 95 % CI, 0.57-0.74), and sentinel lymph node biopsy (SLNB) omission (OR, 0.69; 95 % CI, 0.65-0.73). For LV surgeons, breast center accreditation was associated with increased radiotherapy referral (OR, 1.28; 95 % CI, 1.14-1.44) and SLNB omission (OR, 1.47; 95 % CI, 1.23-1.76).
conclusionLow-volume surgeons had greater variability in breast QM performance and may benefit from efforts, including education and strengthening multidisciplinary communication, to improve breast cancer care for vulnerable populations.
