Synthesis and hybridization properties of oligonucleotides containing 2'-O-modified ribonucleotides.
Article in Nucleic acids research, 1993. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
A versatile, general way is described for the introduction of different functional groups into oligonucleotides by means of a simple linker at the 2'-position of the sugar. Nucleotide building blocks carrying lipophilic, intercalating or tertiary amino groups can be placed deliberately at any desired position of oligonucleotides by standard automated oligonucleotide synthesis. Thermal denaturation studies with these oligonucleotides reveal the following general trends: i) Modification with lipophilic n-octyl groups has little if any effect on duplex stability; a destabilizing (lipophilic) substituent is better tolerated at or near the ends than in the middle of the oligo. ii) An intercalating substituent (2-aminoanthraquinone) substantially increases duplex stability. iii) N,N-Dimethyl amino residues also increase duplex stability though to a smaller extent than intercalating residues. iv) Modifications at the 5'-end have a more pronounced influence on the TM than the corresponding 3'-modifications. v) Oligonucleotides modified in such a way show little or no loss in sequence specificity.
