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
In this study, the DNA sequence specificity of four DNA-targeted 9-aminoacridine carboxamide Pt complexes was compared with cisplatin, using two specially constructed plasmid templates. One plasmid contained 5'-CG and 5'-GA insert sequences while the other plasmid contained a G-rich transferrin receptor gene promoter insert sequence. The damage profiles of each compound on the different DNA templates were quantified via a polymerase stop assay with fluorescently labelled primers and capillary electrophoresis. With the plasmid that contained 5'-CG and 5'-GA dinucleotides, the four 9-aminoacridine carboxamide Pt complexes produced distinctly different damage profiles as compared with cisplatin. These 9-aminoacridine complexes had greatly increased levels of DNA damage at CG and GA dinucleotides as compared with cisplatin. It was shown that the presence of a CG or GA dinucleotide was sufficient to reveal the altered DNA sequence selectivity of the 9-aminoacridine carboxamide Pt analogues. The DNA sequence specificity of the Pt complexes was also found to be similarly altered utilising the transferrin receptor DNA sequence.
