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

Aggressive breast cancer subtypes, such as triple-negative breast cancer (TNBC) and tumors in BRCA1 germline mutation carriers, present significant clinical challenges. The role of BRCA1 protein expression, assessed via immunohistochemistry (IHC), in defining the biology of these high-risk tumors remains to be fully elucidated. We performed a semi-quantitative IHC analysis of BRCA1 protein expression in a targeted cohort of 100 invasive breast carcinomas, enriched for TNBC (88%) and BRCA1 mutation carriers (34%). A validated monoclonal antibody and a composite scoring system (0-9) were employed, with an optimal cut-off defined by ROC analysis. Associations with clinicopathological parameters and p16 expression were evaluated. Low BRCA1 expression was strongly associated with an aggressive phenotype, including invasive ductal histology, hormone receptor negativity, and the TNBC subtype (all
