The Use of Coffee Aroma for Stress Reduction in Postgraduate Dental Students.

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
objectivesThis study aimed to investigate the potential reduction of academic stress related to a graded oral presentation in postgraduate dental students using coffee aromatherapy.
methodsHealthy postgraduate dental students in a seminar class were divided into coffee (n = 32) and control (n = 26) groups. There were 3 modes of aroma distribution: personal distribution with a coffee pad attached to a lanyard, a lanyard plus a personal fan for ventilation of the aroma, and the typical method of the diffuser to spread the aroma in the ambient air. Stress markers comprised levels of salivary alpha-amylase (sAA), cortisol (sCort), and chromogranin A (sCgA). Pulse rates were also measured.
resultsLevels of sAA increased 176.62% ± 30.26% between pre- and postpresentation in the control group. Inhaling coffee aroma during the presentation period significantly ameliorated sAA increase at 81.02% ± 14.90% (P = .015). sCort levels tended to decrease in the coffee group, but not significantly. Surprisingly, sCgA levels increased more in the coffee group. Also, pulse rates decreased in the coffee group (-2.07 ± 2.81 bpm) and increased in the control group (6.90 ± 3.22 bpm; P = .035). Subgroup analysis did not reveal differences in salivary markers amongst the 3 aroma distribution modes.
conclusionsCoffee aroma could have an anxiolytic effect on postgraduate dental students, as evidenced by changes in sAA levels and pulse rates. Personal aroma distribution was also a useful and effective mode of aromatherapy.
