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

backgroundThis study was conducted to describe present and changing trends in surgical modalities and neoadjuvant chemotherapy (NACT) in female breast cancer patients in China from 2006 to 2015.

methodsData of 44 299 female breast cancer patients from 15 tertiary hospitals in Beijing were extracted from hospitalization summary reports. Surgeries were categorized into five modalities: breast-conserving surgery (BCS), simple mastectomy (SM), modified radical mastectomy (MRM), radical mastectomy (RM), and extensive radical mastectomy (ERM).

resultsIn total, 38 471 (86.84%) breast cancer patients underwent surgery: 22.64% BCS, 8.22% SM, 63.97% MRM, 4.24% RM, and 0.93% ERM. Older patients (> 60) underwent surgery more frequently than younger patients (< 60). The proportion of patients who underwent BCS was highest in the age ≥ 80 (39.24%) and < 40 (28.69%) subgroups and in patients with papillary carcinoma (35.48%), and lowest in the age 60- subgroup (18.17%) and in patients with Paget's disease (19.05%). SM was most frequently performed in patients with Paget's disease (29.00%), and MRM for ductal (64.99%), and lobular (63.78%) carcinomas. During the study period, the proportion of patients who underwent MRM dropped by 29.04%, SM and BCS increased from 15.78% and 30.83%, respectively, and NACT increased in all subgroups, particularly in patients with lymph node involvement (26.72%).

conclusionsSurgical modalities varied significantly by age and histologic group. The use of BCS and SM increased dramatically, while MRM declined significantly. The proportion of patients treated with NACT has increased significantly, especially in patients with lymph node involvement.
