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
Targeted protein degradation (TPD) using proteolysis-targeting chimeras (PROTACs) offers advantages over occupancy-based inhibitors but faces challenges, including ligand discovery and cellular permeability. To address these limitations, we developed Re2, a metallo-PROTAC integrating a covalent rhenium(I) complex warhead targeting SARS-CoV-2 main protease (Mpro) Cys145 with the cereblon E3 ligase ligand pomalidomide. Re2 induced effective intracellular Mpro degradation at 100 nM within 72 h, which is significantly below its parent complex's enzymatic inhibition concentration. In vitro and ex vivo studies confirmed covalent Mpro binding and ubiquitin-proteasome system-dependent degradation. Crucially, Re2 exhibited three- to fourfold higher cellular uptake and greater intracellular accumulation than its demetallated organic counterpart, demonstrating that metalation overcomes intrinsic PROTAC permeability barriers. This work establishes metallo-PROTACs, exploiting the tunable coordination chemistry of metal complexes for enhanced target engagement and cellular delivery, as a potent strategy for designing high-potent PROTACs.
