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
Metastatic castration-resistant prostate cancer (mCRPC) is an aggressive subtype of prostate cancer (PC) without curative treatments. Antibody-drug conjugates (ADCs) emerged as promising cancer therapeutics that selectively deliver cytotoxic agents (payloads) to the tumors. Although ADCs have been successfully applied to treat hematological and solid tumors, ADC monotherapy has not demonstrated durable responses in mCRPC, and mechanisms of PC resistance to ADCs have not been thoroughly investigated. Our study aimed to improve ADC efficacy using an integrated approach for a custom ADC design and multiplexing. To nominate rational combinations of ADC targets and payloads, we (a) examined protein coexpression of 3 clinically relevant surface antigens - B7-H3, PSMA, and STEAP1 - in human mCRPCs and (b) screened established ADC payloads and their combinations in mCRPC cell lines with different molecular backgrounds. Identified synergistic interactions between DNA-damaging payloads and the BCL-XL inhibitor A-1331852 as well as their coordinated induction of the intrinsic apoptosis pathway were evaluated in PC cell lines. Functional relevance between isolated p53 loss and PC responses to 3 genotoxic ADCs - B7-H3-seco-DUBA, PSMA-SG3249, and STEAP1-DXd - and their combinations with A-1331852 were established using genetic knockout models. Lastly, enhanced in vivo antitumor activity of vobramitamab duocarmazine by systemic A-1331852 was shown. Collectively, our findings provide rationale for development of ADC therapies combining genotoxic payloads with BCL-XL inhibitors for mCRPC.
