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
A series of cationic dinuclear p-cymene ruthenium trithiophenolato complexes of the type [(η(6)-p-MeC(6)H(4)Pr(i))(2)Ru(2)(SC(6)H(4)-p-X)(3)](+) (1 X is H, 2 X is Me, 3 X is Ph, 4 X is Br, 5 X is OH, 6 X is NO(2), 7 X is OMe, 8 X is CF(3), 9 X is F, 10 X is Pr(i), 11 X is Bu(t)) have been synthesized from the reaction of [(η(6)-p-MeC(6)H(4)Pr(i))RuCl(2)](2) with the corresponding thiol, isolated as the chloride salts, and further studied for their electrochemical properties, cytotoxicity towards human ovarian cancer cells, and catalytic activity for glutathione (GSH) oxidation. Complex 1 was also compared with the benzene and hexamethylbenzene analogues [(η(6)-C(6)H(6))(2)Ru(2)(SC(6)H(5))(3)](+) (12) and [(η(6)-C(6)Me(6))(2)Ru(2)(SC(6)H(5))(3)](+) (13). The most active compound [11]Cl was structurally studied by single-crystal X-ray diffraction analysis. The concentrations corresponding to 50 % inhibition of cancer cell growth (IC(50) values) in the A2780 and A2780cisR cell lines of these complexes except for 6 were in the submicromolar range, complex 11 showing an IC(50) value of 0.03 µM in both cell lines. The high in vitro anticancer activity of these complexes may be at least partially due to their catalytic potential for the oxidation of GSH, although there is no clear correlation between the IC(50) values and the turnover frequencies at about 50 % conversion. However, the cytotoxicity is tentatively correlated to the physicochemical properties of the compounds determined by the electronic influence of the substituents X (Hammett constants σ(p)) and the lipophilicity of the thiols p-XC(6)H(4)SH (calculated log P parameters).
