Comparative Binding Affinities of Platinum-Based Drugs toward Purine Alkaloids and Nucleobases.
Article in ACS omega, 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
Platinum-based anticancer drugs are among the most commonly used agents in cancer therapy. In particular, carboplatin, cisplatin, and oxaliplatin have been used in both monotherapies and combination therapies for many years. The main targets of these compounds are nucleobases in DNA. By creating cross-links, they inhibit cell development and lead to apoptosis. Recent studies indicate that platinum-(II) drugs can interact with other compounds with structures similar to nucleobases. For this reason, the current study analyzed the interactions of carboplatin, cisplatin, and oxaliplatin with nucleobases and purine alkaloids (caffeine, theobromine, theophylline) using spectroscopic and computational chemistry methods. Theoretical studies indicated that cytostatics exhibit affinity not only for nucleobases but also for purine alkaloids. However, cytostatics more easily form complexes with nucleobases compared with alkaloids. Experimental investigations confirmed the results of these theoretical studies.
