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

backgroundUnderstanding the size and surface charge (ζ-potential) of particles in the mixed micellar fraction produced by in vitro digestion is crucial to understand their cellular absorption and transport. The inconsistent presentation of micellar size data, often limited to average particle diameter, makes comparison of studies difficult. The present study aimed to assess different size data representations (mean particle diameter, relative intensity- or volume-weighted size distribution) to better understand physiological mixed micelle characteristics and to provide recommendations for size reporting and sample handling.

resultsDietary compounds (RRR-α-tocopherol, retinyl-palmitate, β-carotene, curcumin and naringenin) underwent a simplified in vitro digestion, whereas foods (spinach and red cabbage) were subjected to both a simplified and the INFOGEST 2.0 digestions. Dynamic light scattering was used to measure size and surface charge of the mixed micelles. A significant percentage of particles above the 200 nm filter cut-off was observed, indicating aggregation and dynamic size changes in the mixed micellar fraction. Freezing of the mixed micelles notably enhanced the aggregation.

conclusionThe determination of particle size in polydisperse mixed micellar fractions is challenging, and relying solely on average particle diameter can be misleading. Especially in more polydisperse samples, parameters such as polydispersity index and volume-weighted distribution should accompany average particle diameter data. To minimize the effect of freezing on particle size, we recommend filtering the digesta after storage (freezing), as this leads to similar size distribution compared to mixed micellar fraction measured directly after digestion. © 2025 The Author(s).
