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

Objectives: Neoadjuvant chemotherapy with dual HER2 blockade is the standard of care for early-stage HER2-positive breast cancer. However, the role of anthracyclines remains controversial. This meta-analysis aimed to evaluate the efficacy and safety of neoadjuvant dual HER2 blockade combined with anthracycline-containing vs. anthracycline-free chemotherapy. Methods: A literature search was conducted across PubMed, EMBASE, and the Cochrane Library. Eligible studies included patients with resectable stage I-III HER2-positive breast cancer receiving neoadjuvant dual HER2 blockade with either an anthracycline-containing (A-based) or anthracycline-free (non-A) chemotherapy regimen. Standard meta-analytic methods using a random-effects or fixed-effect model were applied according to heterogeneity (I Results: Seven articles met the inclusion criteria. The addition of anthracyclines to dual HER2 blockade therapy (DHBT) did not significantly improve the pCR rate (OR, 1.07; 95 % CI, 0.81-1.43; p=0.62), composite DFS/EFS/PFS (HR, 0.50; 95 % CI, 0.18-1.38; p=0.18), or overall survival (OS) (HR, 0.77; 95 % CI, 0.39-1.51; p=0.45). The incidence of cardiac adverse events did not differ significantly between the A-based and non-A groups (OR, 0.96; 95 % CI, 0.31-2.91; p=0.94). No significant difference was observed in the incidence of LVEF decline ≥10 % from baseline to <50 % between the A-based and non-A groups (OR, 1.47; 95 % CI, 0.79-2.77; p=0.23). Notably, the non-A group had a significantly higher incidence of grade ≥3 diarrhea (OR, 0.60, favoring the A-based group; 95 % CI, 0.38-0.95; p=0.03). Conclusions: In resectable HER2-positive breast cancer, neoadjuvant DHBT without anthracyclines achieves pCR rates non-inferior to A-based regimens, with no early survival detriment observed. While short-term cardiotoxicity is unremarkable, grade ≥3 diarrhea occurs more frequently with non-A approaches.
