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: Neoadjuvant chemotherapy (NACT) is increasingly employed for locally advanced breast cancer in Nigeria, but treatment outcomes remain heterogeneous and often uncertain relative to global standards. Methodology: We systematically reviewed Nigerian studies on NACT outcomes using PubMed, Embase, Scopus, Web of Science, AJOL, and grey literature through September 2025. Eligible studies included women receiving NACT who reported an objective response rate (ORR) or a pathologic complete response (pCR). Quality was assessed using ROBINS-I or RoB-2, and certainty was rated using GRADE. Pooled estimates were generated with random-effects (DerSimonian-Laird) models. Results: Eleven studies (n = 629 women) met the inclusion criteria. Early anthracycline-based cohorts showed ORR = 51-93% with rare pCR. Contemporary anthracycline-taxane regimens achieved pCR ≈ 20%, the highest in HER2-positive and triple-negative disease. Pooled ORR = 66% (95% CI: 55-76%; I Conclusions: NACT in Nigeria achieves consistent clinical downstaging but modest pCR outside HER2-targeted settings. Expanding access to biomarker testing, taxanes, trastuzumab (including biosimilars), and ensuring therapy completion are essential to close the global outcome gap.
