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
This study investigated the printability and textural properties of 3D-printed pectin-κ-carrageenan hydrogels with varying polysaccharide ratios. Inks with 50 and 60% κ-carrageenan exhibited optimal printability, producing structures consistent with digital designs. Rheological temperature sweep tests showed increased viscosity and moduli with higher κ-carrageenan content, affecting extrusion behavior. Hydrogels printed with high-methoxyl (HM) pectin were softer, less cohesive, and more adhesive than those with low-methoxyl (LM) pectin, attributable to lower network strength confirmed by rheological tests. Sensory evaluations favored HM hydrogels for ease of swallowing and taste, supported by reduced chewing effort and enhanced saliva absorption. These findings demonstrate that κ-carrageenan improves pectin ink printability and enables fabrication of edible gels with tunable texture for personalized nutrition.
