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

backgroundThe reasons for increasing rates of bilateral mastectomy for unilateral breast cancer are incompletely understood, and associations of disease stage with bilateral surgery have been inconsistent. We examined associations of clinical and sociodemographic factors, including stage, with surgery type and reconstruction receipt among women with breast cancer. PATIENTS AND

methodsWe surveyed a diverse population-based sample of women from Northern California cancer registries with stage 0 to III breast cancer diagnosed during 2010-2011 (participation rate, 68.5%). Using multinomial logistic regression, we examined factors associated with bilateral and unilateral mastectomy (vs. breast-conserving surgery), adjusting for tumor and sociodemographic characteristics. In a second model, we examined factors associated with reconstruction for mastectomy-treated patients.

resultsAmong 487 participants, 58% had breast-conserving surgery, 32% had unilateral mastectomy, and 10% underwent bilateral mastectomy. In adjusted analyses, women with stage III (vs. stage 0) cancers had higher odds of bilateral mastectomy (odds ratio [OR], 8.28; 95% confidence interval, 2.32-29.50); women with stage II and III (vs. stage 0) disease had higher odds of unilateral mastectomy. Higher (vs. lower) income was also associated with bilateral mastectomy, while age ≥ 60 years (vs. < 50 years) was associated with lower odds of bilateral surgery. Among mastectomy-treated patients (n = 206), bilateral mastectomy, unmarried status, and higher education and income were all associated with reconstruction (P < .05).

conclusionIn this population-based cohort, women with the greatest risk of distant recurrence were most likely to undergo bilateral mastectomy despite a lack of clear medical benefit, raising concern for overtreatment. Our findings highlight the need for interventions to assure women are making informed surgical decisions.
