1 · What the graph read from it

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.

2 · The registry

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

The conformations of glycyl-L-leucine oligomers (GnL, residue number n = 3, 4, and 5) in the solid state were found to be similar to that of a polyglycine II (PGII). However, for L-leucyl-glycine oligomers (LGn; n = 3, 4, 5) in the solid state, LG3 and LG4 have already been confirmed to take a reverse-turn structure (LG3-type reverse-turn) while LG5 adopts a PGII-type helix. The present results provide evidence that the conformations of L-leucine-containing glycine oligomers depend strongly upon whether the L-leucine residue is placed in the N- or C-terminal position. For the aqueous G3L and G4L samples, we assumed that reverse-turn structures similar to the type II β-turn, rather than the LG3-type reverse-turn, are stabilized in concentrated solution, probably as the result of aggregation. Models to explain the mechanism of these phenomena are presented.
