Enhancement of Cytotoxicity of Enediyne Compounds by Hyperthermia: Effects of Various Metal Complexes on Tumor Cells.
Article in Radiation research, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Enediyne natural products are a class of compounds that were recognized for their potential as chemotherapeutic agents many years ago, but found to be highly cytotoxic due to their propensity for low thermal activation. Bergman cyclization of the enediyne moiety produces a diradical intermediate, and may subsequently induce DNA damage and account for the extreme cytotoxicity. While difficulties in controlling the thermal cyclization reaction have limited the clinical use of cyclic enediynes, we have previously shown that enediyne activity, and thus toxicity at physiological temperatures can be modulated by metallation of acyclic enediynes. Furthermore, the cytotoxicity of "metalloenediynes" can be potentiated by hyperthermia. In this study, we characterized a suite of novel metallated enediyne motifs that usually induced little or no cytotoxicity when two different human cancer cell lines were treated with the compounds at 37°C, but showed a significant enhancement of cytotoxicity after cells were exposed to moderate hyperthermia during drug treatment. Cultured U-1 melanoma or MDA-231 breast cancer cells were treated with various concentrations of Cu, Fe and Zn complexes of the enediyne (
