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

l-Ascorbic acid (LAA) is considered a powerful antioxidant that protects skin from premature aging. Maintaining the stability of vitamin C remains the biggest challenge in cosmeceuticals. Our main aim is the entrapment of high dose of vitamin C in spanlastic vesicles to provide maximum stability and efficacy. LAA-loaded spanlastics were prepared by ethanol injection method and were characterized for entrapment efficiency (EE%), particles size (PS), polydispersity index (PDI), zeta potential, deformability index (DI) and
