Conformational properties of DNA dodecamers containing four tandem repeats of the CNG triplets.
Article in Nucleic acids research, 1998. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
We studied DNA dodecamers (CAG)4, (CCG)4, (CGG)4 and (CTG)4by CD spectroscopy and polyacrylamide gel electrophoresis. Each dodecamer adopted several ordered conformers which denatured in a cooperative way. Stability of the conformers depended on the dodecamer concentration, ionic strength, temperature and pH. The dodecamers, having a pyrimidine base in the triplet center, generated foldbacks at low ionic strength whose stem conformations were governed by the GC pairs. At high salt, (CCG)4 isomerized into a peculiar association of two strands. The association was also promoted by high oligonucleotide concentrations. No similar behavior was exhibited by (CTG)4. At low salt, (CGG)4 coexisted in two bimolecular conformers whose populations were strongly dependent on the ionic strength. In addition, (CGG)4 associated into a tetraplex at acidic pH. A tetraplex was even observed at neutral pH if the (CGG)4 concentration was sufficiently high. (CAG)4 was very stable in a monomolecular conformer similar to the known extremely stable foldback of the (GCGAAGC) heptamer. Nevertheless, even this very stable conformer disappeared if (CTG)4 was added to the solution of (CAG)4. Association of the complementary strands was also strongly preferred to the particular strand conformations by the other couple, (CCG)4 and (CGG)4.
