Article in Protein and peptide letters, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeThis study compares the activity of BRCA-1 mimetics on WTp53 (wild-type p53 protein) and MTp53 (mutated-type p53 protein) proteins, examining the impact of TP53 mutations in breast cancer. p53 activators can be a new insight and synthesis of effective compounds for the treatment of cancer. The project contributes to the growing body of research on p53 activators and provides new insights into the design and synthesis of effective compounds for the treatment of cancer.
methodsMolecular docking predicted binding affinity values for WTp53 and MTp53. The MMGBSA of top compounds was run to get binding-free energies. The MD simulations were calculated, and six metal coordinates were synthesized.
resultsThe p53 activators established a three-featured (2RA, 1HBA) pharmacophore. The designed compounds had better Glide gscore compared to p53 activators PRIMA-1, PRIMA-1- MET (methylated PRIMA-1), and Tamoxifen with p53 protein (WTp53, R175H and R273H MTp53). The MM-GBSA results of top compounds showed binding free energies with R175HMTp53 (-22.24 to -75.45 kcal/mol), R273H-MTp53 (-22.8 to -36.36 kcal/mol), and WTp53 (-26.45 to -50.3 kcal/mol) compared to the p53 activator. The MD simulation of TSCO5/3KMD-MT in 100 ns indicated a stable complex when compared to TSCO5/3KMD-WT. The six metal coordinates (TSCO5-Zn, TSCO6-Zn, TSCO6-Sn, TSCO13-Zn, TSCO13-Sn, TSCO9-Sn) were synthesised. Based on
conclusionAs compared to PRIMA-1, the designed compound TSCO5 metal coordinates have shown good
