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

Four new kahalalides, V (1), W (2), X (3), and Y (4), as well as six previously characterized kahalalides have been isolated from a two-year collection of the sacoglossan mollusk Elysia rufescens. Curiously, kahalalide B, previously isolated in high yield from E. rufescens, was found to be essentially absent from these collections despite identical collection sites and times with previous collections. In addition, kahalalide K, which to date has only been reported from Bryopsis sp., was found in this collection of E. rufescens, suggesting that the production of these metabolites could potentially be from a microbial association with the mollusk and algae, and this relationship is continuously evolving in response to changes in the environment and predation. The structures of new peptides have been established on the basis of extensive 1D and 2D NMR spectroscopic data analysis. Kahalalide V (1) was ascertained to be an acyclic derivative of kahalalide D (5), while kahalalide W (2) was determined to have a 4-hydroxy-L-proline residue instead of the proline in 5. The arginine residue of kahalalide X (3), an acyclic derivative of kahalalide C, was determined to have an L configuration. Kahalalide Y (4) was found to have an L-proline residue instead of the hydroxyproline in kahalalide K. It is clear from this collection of E. rufescens that the discovery of new kahalalide-related metabolites is still highly feasible.
