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
BMI1, a constituent of polycomb repressive complex 1, is overexpressed in a variety of cancers, including neuroblastoma, highlighting its potential as a target for cancer therapeutics. Given the pivotal role of BMI1, a number of inhibitors have been synthesized and assessed for therapeutic efficacy across a spectrum of cancers. In our present study, the BMI1 inhibitors PTC-028 and PTC-209 exhibited selective antitumor activity against MYCN-amplified neuroblastoma. Notably, PTC-028, which exhibited toxicity at lower concentrations, triggered apoptosis in neuroblastoma cells and induced G1-phase accumulation, along with reductions in S-phase and G2/M-phase populations, thereby promoting cell cycle arrest. Thorough RNA sequencing analyses revealed that PTC-028 treatment activated the p53 signaling pathway, suggesting it plays a critical role in the mechanism of apoptosis induction. Moreover, PTC-028 treatment led to decreases in levels of anti-apoptotic proteins, including BCL2 and MCL1. Significantly, PTC-028 also exhibited antitumor efficacy in a mouse xenograft model of human neuroblastoma. These results suggest that BMI1 inhibitors, particularly PTC-028, are promising therapeutic agents for the management of aggressive MYCN-amplified neuroblastomas.
