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

The prostate-specific membrane antigen (PSMA)-targeted radioligand [¹⁷⁷Lu]Lu-PSMA-617 is a new standard treatment for metastatic castration-resistant prostate cancer (mCRPC), but predictive genomic biomarkers informing its rational use are unknown. We performed detailed dissection of prostate cancer driver genes across 290 serial plasma cell-free DNA samples from 180 molecular imaging-selected patients with mCRPC from the randomized TheraP trial of [¹⁷⁷Lu]Lu-PSMA-617 (n = 97) versus cabazitaxel chemotherapy (n = 83). The primary endpoint was PSA50 biochemical response, with secondary endpoints of progression-free survival (PFS) and overall survival (OS). In this post-hoc biomarker analysis, a low pretreatment circulating tumor DNA (ctDNA) fraction predicted a superior biochemical response (100% versus 58%, P = 0.0067) and PFS (median 14.7 versus 6.0 months; hazard ratio 0.12, P = 2.5 × 10
