Trastuzumab Induces Apoptosis and Cell Cycle Arrest in Triple-Negative Breast Cancer, Suggesting Repurposing Potential.
Article in Breast cancer : basic and clinical research, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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.
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 the most common invasive cancer in women worldwide. Triple-negative breast cancer (TNBC) is an aggressive subtype with limited treatment options. Trastuzumab (Tz) is typically used to treat HER2-positive breast cancers, but its potential in TNBC is unclear. Objectives: To investigate the effects of trastuzumab on cell viability, apoptosis, cell cycle progression, and gene expression in TNBC cell lines compared with HER2-positive and normal cell lines. Design: This is an in vitro experimental pre-clinical study using cultured cancer cell lines. Methods: MDA-MB-231 and 4T1 (TNBC), MCF-7 ( Results: Trastuzumab significantly reduced cell viability and induced apoptosis in TNBC cell lines, comparable to effects in HER2-positive MCF-7 cells. Cell cycle analysis revealed G2/M phase arrest in TNBC cells. Gene expression analysis showed upregulation of ERBB2, Conclusion: This study provides initial evidence for trastuzumab's potential therapeutic effects in TNBC, despite low
