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

Background: Breast cancer remains a leading cause of morbidity and mortality among women worldwide, with significant geographic disparities in its impact. While human epidermal growth factor receptor 2 (HER2)-targeted therapies, such as trastuzumab, have improved outcomes for HER2-positive breast cancer, challenges like therapy resistance persist, highlighting the need for novel treatments. Recent developments in antibody-drug conjugates (ADCs), particularly disitamab vedotin (RC48), show promising efficacy in targeting both HER2-positive and HER2-low expression tumors, warranting further investigation through real-world studies to assess its broader clinical applicability. Method: This retrospective, multicenter observational study evaluated the real-world efficacy and safety of RC48 in patients with HER2-positive or HER2-low breast cancer across three medical centers in China. Patient demographic characteristics, treatment patterns, sequential use of ADCs, and treatment-related adverse events were recorded and analyzed. Result: The median progression-free survival (mPFS) for the overall population ( Conclusion: This real-world study demonstrates the efficacy of RC48 in both HER2-positive and HER2-low breast cancer. Notably, combination therapy significantly improved outcomes in HER2-low patients.
