Stability of single-nucleotide bulge loops embedded in a GAAA RNA hairpin stem.

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
Forty-six RNA hairpins containing combinations of 3' or 5' bulge loops and a 3' or 5' fluorescein label were optically melted in 1 M NaCl, and the thermodynamic parameters ΔH°, ΔS°, ΔG°(37), and T(M) for each hairpin were determined. The bulge loops were of the group I variety, in which the identity of the bulge is known, and the group II variety, in which the bulged nucleotide is identical to one of its nearest neighbors, leading to ambiguity as to the exact position of the bulge. The fluorescein label at either the 3' end or 5' end of the hairpin did not significantly influence the stability of the hairpin. As observed with bulge loops inserted into a duplex motif, the insertion of a bulge loop into the stem of a hairpin loop was destabilizing. The model developed to predict the influence of bulge loops on the stability of duplex formation was extended to predict the influence of bulge loops on hairpin stability. Specifically, the influence of the bulge is related to the stability of the hairpin stem distal from the hairpin loop.
