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

backgroundAnatomical and functional changes in the lactating breast may increase the risk of complications after surgical intervention. We examined postoperative complications in peripartum patients undergoing breast surgery. PATIENTS AND

methodsThis retrospective study included pregnant and postpartum patients undergoing oncologic breast surgery from 1989 to 2022. Primary outcome was 90-day complication rate. Patients > 20 weeks gestational age or postpartum were considered to have lactational breast changes. Descriptive statistics and logistic regression analyses were performed.

resultsOf 164 patients, most had high-grade (n = 104, 66.7%), ductal (141, 89.8%), clinical stage II-III (n = 143, 87.2%) invasive carcinoma, and 59.8% (n = 98) received neoadjuvant chemotherapy (NAC). The post-biopsy complication rate was 0.63% (1/160, seroma). At time of surgery, 63 patients (38.4%) were pregnant and 101 (61.6%) were postpartum; 122 (75.0%) had lactational breast changes. The complication rate after surgery (72% total mastectomy, 28% segmental mastectomy) was 12.2% (95% CI 7.6-18.2). Surgical site infection was the most common (n = 10, 6.1%), followed by fluid collections (n = 7, 4.9%; six seromas, one hematoma), and mastectomy flap necrosis (n = 2, 1.2%). No milk fistulae were observed. Postoperative complications were not associated with lactational breast changes in logistic regression models controlling for either extent of breast surgery or NAC receipt (p > 0.05).

conclusionsIn the largest reported cohort of peripartum patients undergoing breast surgery, the postoperative complication rate was low, irrespective of lactational breast changes, and similar to published rates for the general population. These results support timely surgical treatment of pregnant and postpartum patients per standard of care regardless of lactational status.
