1 · What the graph read from 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.

2 · The registry

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

backgroundRe-operation after breast-conserving surgery for invasive breast cancer is variable among centres and individual surgeons. In this study, we aimed to characterize the current landscape of practice regarding re-operation for invasive breast cancer in the province of Alberta.

methodsThis study was a retrospective review of the Synoptec database for patients undergoing primary breast-conserving surgery for invasive breast cancer or reoperation in the province of Alberta in the year 2020. We extracted data on demographic and tumour characteristics, use of intraoperative margin-assessment strategies, and surgical facility. We conducted univariate and multivariate logistic model analyses.

resultsWe included 1391 breast surgeries in the study. A total of 158 patients underwent re-operation during the study period. The median time to first reoperation was 34 days. The overall re-operation rate was 11.4% (range 5.4%-18.5%) among surgical facilities. The completion mastectomy rate was 5.2%, and 1.5% of patients underwent multiple revisional surgeries. Tumour multifocality was associated with increased revisional surgery rates on multivariate analysis (odds ratio 2.80).

conclusionThe results of this study are consistent with the published literature. We have identified heterogeneity among sites in Alberta for revisional surgery after breast-conserving surgery for invasive breast cancer. This highlights an opportunity for ongoing education and quality improvement in breast cancer care in the province of Alberta.
