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

Poly(ADP-ribose) polymerase inhibitors are an important option for metastatic castration-resistant prostate cancer (mCRPC) with homologous recombination repair gene alterations, although durable complete responses remain rare. We report a 72-year-old man with BRCA2-mutated mCRPC who achieved a sustained complete response to olaparib monotherapy. After progression on androgen deprivation therapy, abiraterone, enzalutamide, and docetaxel, genomic profiling identified a pathogenic BRCA2 alteration. Olaparib induced an undetectable prostate-specific antigen within three months, maintained for over 27 months, with complete resolution of bone metastases. This case highlights the potential for durable responses to olaparib and the importance of early genomic testing.
