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

Fatty acids derived from waste cooking oil (WCO) are successfully processed as sustainable phase-change materials (PCMs) for thermal energy storage. This study investigated the conversion of WCO into fatty acid-based PCMs through hydrolysis and hydrogenation, optimizing reaction parameters to enhance thermal properties. A logarithmic model was developed to describe the relationship between hydrogenation time and the adjustment of melting point. The study also examined the correlation between WCO-derived fatty acids (WCOFAs) and their chemical structure, providing insights into optimizing hydrogenation conditions to achieve desired melting points (between 15 °C and 60 °C). The effects of different oil mixtures on thermal characteristics, such as melting point and latent heat, were analyzed to tailor WCOFA-based PCMs for industrial applications. Experimental results indicated that increasing hydrogenation time reduces carbon-carbon double bonds, increasing the melting point and latent heat, with fully hydrogenated WCOFAs exhibiting properties comparable to those of commercial PCMs (∼150 J g
