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 hexapeptide ALA-ASP-LEU-LYS-PRO-THR is currently widely used as an active ingredient in commercially available creams. Therefore, the proper analytical procedure to detect this compound is a very important issue. This paper presents the determination of the hexapeptide in solution and in cosmetic formulations by matrix assisted laser desorption ionisation mass spectrometry. We developed a procedure for the selective binding of the low molecular weight peptide by using a two-component matrix which enabled us to characterize the hexapeptide directly without any initial processing. Furthermore, the extensive computer simulations were carried out to assist in this analysis of the MS spectra.
