On combinatorial and biofunctional symmetries hidden in polynucleotide sequences.

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
Various types of symmetry of polynucleotide sequences and methods of their algebraic description are considered. Among the methods of description, the main attention is paid to the application of semigroup theory (in particular, group theory). For convenience, all symmetry is divided into types. Combinatorial symmetry, first of all, it is associated with the explicit and hidden periodicity of the arrangement of identical nucleotides in subsequences. The above is generalized to the case of color symmetry, when different types of nucleotides or their associations can transform into each other upon shift. Fractal symmetry can also be added to this. Biofunctional symmetry means the presence of sequence factors of different nature (and size), which can be interchanged (swap places) solely due to their biological equivalence in the strand. A number of issues that are indirectly related to symmetry are also touched upon, for example, the presence of closed loops in polynucleotide (or polypeptide) chains and some physicochemical aspects.
