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

Mycosporine-like amino acids (MAAs) are photoprotective compounds primarily produced by marine organisms, especially red algae. Chemically, MAAs and their precursors are low-molecular-weight natural products that absorb ultraviolet radiation in the range of 270-360 nm without generating free radicals. Owing to these properties, MAAs have attracted considerable interest for potential pharmaceutical and cosmetic applications as natural sunscreen agents. In this study, the first hydrophilic interaction liquid chromatography-ultra-performance liquid chromatography (HILIC-UPLC) method, coupled with both diode array detector (DAD) and tandem mass spectrometry (MS/MS), was developed for the determination of 11 MAAs and 2 MAA precursors in various algal species. As column, a YMC-Triart Diol-HILIC (particle size: 1.9 µm) was used, and the separation of the MAAs realized in under 5 min. The validation of the method was carried out following International Council for Harmonisation (ICH) guidelines, demonstrating linearity, selectivity, precision, and accuracy. The analysis of extracts prepared from well-known species, such as Porphyra sp. and Chondrus crispus, confirmed practical applicability. Demonstrating feasibility of MS/MS-based quantification of co-eluting compounds, the method represents an appealing alternative that surpasses established procedures not only in terms of analysis time but also by providing a substantially increased informative value.
