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
Neoadjuvant chemoimmunotherapy with pembrolizumab now defines the standard of care for early high-risk triple-negative breast cancer (TNBC). However, the role of pembrolizumab in neoadjuvant therapy (NAT) for estrogen receptor-positive (ER+) breast cancer remains uncertain. A 39-year-old G2P2 female discovered a palpable mass in the right breast while breastfeeding her 7-month-old child, leading to the diagnosis of a high-grade ER+ (80% moderate staining), human epidermal growth factor receptor 2-negative (ErbB2-) invasive ductal carcinoma with axillary nodal involvement. Gene expression profiling with the MammaPrint 70-gene signature and BluePrint 80-gene signature revealed a tumor with high-risk, basal-type biology. The multidisciplinary breast cancer team recommended NAT with pembrolizumab, carboplatin, paclitaxel, doxorubicin, and cyclophosphamide. Within six weeks, the patient exhibited a remarkable response, with no palpable mass or lymph node, and post-treatment examinations confirmed a complete clinical and radiologic response. The patient underwent lumpectomy and sentinel lymph node biopsy, revealing a pathological complete response with minimal ductal carcinoma in situ and negative axillary nodes. Adjuvant radiation therapy was administered, and the patient completed adjuvant pembrolizumab, currently showing no evidence of recurrence. This case underscores the potential benefits of neoadjuvant chemoimmunotherapy for patients with ER+ErbB2- high-risk, basal-type breast cancer. The use of immunotherapy in patients with pregnancy-associated breast cancer remains to be further investigated.
