Nanodispersion of lutein with use of metastable polymorph for improved dissolution and oral absorption.

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.
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
Lutein (LT) is an attractive nutrient for eye health, although it has low water solubility and poor oral absorption. The present study aimed to develop a novel nanodispersion (ND) of LT using a metastable polymorph, offering improved oral absorption of LT. A metastable crystalline form of LT (LT-II) and hydroxypropyl cellulose were subjected to wet-milling followed by freeze-drying to obtain the ND of LT-II (ND/LT-II), and its physicochemical, photochemical, and pharmacokinetic properties of LT samples were evaluated. The mean particle size of LT-II in ND/LT-II was 354 nm, and there was no significant change in the crystalline form of LT-II, even after wet milling and freeze-drying. LT generated significant amounts of superoxide anions upon exposure to pseudo-sunlight (250 W/m
