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

purposeThe detection of fat taste in humans requires the delivery of hydrophobic stimuli to the oral cavity. Due to their low solubility in water, these fat taste stimuli are difficult to administer to test subjects by means of aqueous solutions or dispersions. These hydrophobic stimuli are also difficult to prepare in sufficient amounts to generate an appreciable chemosensory response.

methodsAn improved procedure for preparing thin edible strips that contain 18-carbon fatty acids as representative fat taste stimuli is described. This protocol includes the addition of low amounts of the dispersing agent xanthan gum and high drying temperature during film formation. These edible strips can be prepared in 4-5 h, are highly flexible, and evenly disperse long-chain fatty acids at micromole amounts. Due to the rapid dissolving time of these strips in the oral cavity, this delivery method generates minimal tactile responses.

resultsPsychophysical studies with edible strips indicate that nearly all individuals detected linoleic acid, with intensity responses in the weak to moderate range. Fewer individuals perceived stearic acid, with most intensity responses in the barely detectable range. Both fatty acids caused a fatty/oily or bitter taste response in the majority of test subjects. Finally, these intensity responses allowed the development of edible circles for regional testing of the tongue.

conclusionThis novel delivery method for hydrophobic stimuli should be useful for examining human fat taste perception, characterizing variations in fat taste perception, and identifying the emerging role of fat taste in human health.
