Summary of findings 2. Armodafinil versus placebo for sleepiness caused by shift work.

Armodafinil versus placebo for sleepiness caused by shift work
Patient or population: patients with sleepiness caused by shift work
 Settings: work setting
 Intervention: Armodafinil versus placebo
Outcomes Illustrative comparative risks* (95% CI) Relative effect
 (95% CI) No of participants

Control Armodafinil versus placebo
Sleepiness during the night shift 
 KSS at final visit.
Scale from: 1 to 9. Follow‐up: mean 3 months
The mean sleepiness during the night shift in the control groups was
 6 score points of KSS The mean sleepiness during the night shift in the intervention groups was
 0.99 lower 
 (1.32 to 0.67 lower) 572

Sleep latency 
 MSLT.
Scale from: 0 to 20 minutes.
 Follow‐up: mean 3 months
The mean sleep latency in the control groups was
 5.3 minutes on MSLT The mean sleep latency in the intervention groups was
 2.5 higher 
 (1.36 to 3.64 higher) 216

*The basis for the assumed risk (e.g. the median control group risk across trials) is provided in footnotes. The corresponding risk (and its 95% CI) is based on the assumed risk in the comparison group and the relative effect of the intervention (and its 95% CI).
 CI: Confidence interval; Karolinska Sleepiness Scale (KSS); Multiple sleep latency test (MSLT).
GRADE Working Group grades of evidence
 High quality: Further research is very unlikely to change our confidence in the estimate of effect.
 Moderate quality: Further research is likely to have an important impact on our confidence in the estimate of effect and may change the estimate.
 Low quality: Further research is very likely to have an important impact on our confidence in the estimate of effect and is likely to change the estimate.
 Very low quality: We are very uncertain about the estimate.

1 We included one trial at unclear risk of bias and one at low risk of bias.
 2 This is a laboratory test and not a field test.
 3 There was only one included trial.
