Yeast Saccharomyces cerevisiae as a model system to study the cytotoxic activity of the antitumor drug camptothecin.
Review in Cancer chemotherapy and pharmacology, 1994. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Eukaryotic DNA topoisomerase I catalyzes the relaxation of positively and negatively supercoiled DNA and plays a critical role in processes involving DNA, such as DNA replication, transcription and recombination. The enzyme is encoded by the TOP1 gene and is highly conserved in its amino acid sequence and sensitivity to the anti-neoplatic agent camptothecin. This plant alkaloid specifically targets DNA topoisomerase I by reversibly stabilizing the covalent enzyme-DNA intermediate. Presumably, it is the interaction of these drug-stabilized adducts with other cellular components, such as replication forks, that actually produces the DNA lesions leading to cell death. A conservation of the mechanism(s) of camptothecin-induced cell killing is also implicit in studies of the yeast Saccharomyces cerevisiae, where the camptothecin sensitivity of delta TOP1 yeast cells can be restored by plasmids expressing either yeast or human TOP1 sequences. This genetically tractable system is currently being exploited to describe the specific molecular interactions required for the cytotoxic action of camptothecin. The results of mutational analyses of yeast and human DNA topoisomerase I are presented, as well as a genetic screen designed to identify genes, other than TOP1, that are required for the cytotoxic activity of camptothecin.
