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

backgroundImmediate breast reconstruction (IBR) is a common oncoplastic procedure used in breast cancer surgery. This study aims to investigate compliance with prosthetic breast reconstruction guidelines and its impact on perioperative treatment.

methodsWe reviewed data from the National Clinical Database-Breast Cancer Registry between January 2019 and December 2020. We compared perioperative treatment implementation between the IBR and non-IBR groups by subtype matching for age, menopausal status, T stage, N stage, and histology.

resultsA total of 8,860 patients with breast cancer who underwent IBR (6,075 breast prostheses, 2,492 autologous tissues, and 293 others) were identified. The compliance rate with the guidelines for prosthetic breast reconstruction was 97.7%. After matching, chemotherapy for luminal A-like diseases was significantly less frequent in the IBR group than in the non-IBR group (16.3% vs 20.5%, p < 0.001), and radiotherapy was less frequent in luminal A-like and HER2-positive patients (7.2% vs 9.0%, p = 0.010 and 7.1% vs 11.4%, p = 0.005, respectively). Among the 1-3 node-positive cases, fewer patients with prosthetic IBR received radiotherapy than those without IBR (15.7% vs 26.4%, p < 0.001).

conclusionProsthetic breast reconstruction was performed with strict adherence to the Japanese guidelines. The implementation rates of chemotherapy and radiotherapy were lower in the specific IBR group than those in the non-IBR group. Therefore, large-scale, long-term follow-up data are required.
