Figure Lengend Snippet: Flow chart of the study. A total of 57 participants were screened, of which 6 were excluded. Of these 51 participants, 3 participants withdrew consent. Of the remaining 48 participants, only the 12 participants that received 20 mg oxycodone were included for the analysis.

Article Snippet: Thereafter, participants were administered the medicinal product: oxycodone (20 mg oxycodone HCl Teva, oral immediate release), or one of the three other drugs not discussed in this publication.

Figure Lengend Snippet: Correlation between light intensity and pupil size for different study conditions. Effect of oxycodone intake on pupil size in correlation to the amount of light in the room; home measurements separated from the measurements made during the study visits. This shows that after oxycodone intake, the pupil size is reduced (in both dark- and bright-light settings).

Article Snippet: Thereafter, participants were administered the medicinal product: oxycodone (20 mg oxycodone HCl Teva, oral immediate release), or one of the three other drugs not discussed in this publication.

Figure Lengend Snippet: Dbase (z-pupil size) plotted vs. the log of ambient light measured with the mobile phone. Circles are before and triangles after administration of oxycodone. The classification results from a simple model with Dbase (z-pupil size) and Log light are shown in color. Black triangles are true positives and green triangles false negatives. Blue circles are true negatives and red circles false positives.
