Description of intervention(s) / exposure
Females presenting to ED with a concussion. These patients will provide a saliva sample upon admission to ED when the concussion diagnosis is confirmed to investigate the presence of specific biomarkers and will exit the study when they are asymptomatic and have recovered from the concussion. The number of days it takes to recover will be recorded for a maximum of 3 months.

Statistical methods / analysis
Using PASS15 software, and a Cox Proportional-Hazards regression model it was estimated that the number of partici-pants needed for the primary outcome (recovery time in days) to be statistically and clinically significant is 30. This will detect a hazard ratio of 1.5 (log hazard ratio coefficient = 0.4055), with 80% power, and a type I error rate of 0.05. This was calculated assuming a covariate SD of 1.5, a multiple regression R2 (variable of interest regressed on covariates) of 0.2, and an expected event (clinical recovery) rate of 0.9 within the follow-up period. Based on the power calculation using a 0.2 effect size with 80% power for the range of variables (based on means and SD reported in previous studies within the literature) and allowing for 20% drop out during follow-up, 38 participants will be recruited.

Summary
Brief summary
This study aims to better understand how sex hormones impact on symptom severity and duration and salivary biomarker release in females following concussion and whether levels of hormones are related to symptoms after the injury.

Female sex hormones are linked to brain health and function; more female specific research is needed to understand how sex hormones influence brain injury.

There are differences in the way that males and females experience concussion. Diagnosis and management of concussion is symptom based. Even for highly trained doctors, it can sometimes be difficult to diagnose a concussion, and to understand why someone is having symptoms after injury. It can also be hard to track improvements and changes in symptoms during recovery from concussion to decide if someone is ready to return to school/work or sport. Going back to school/work or sport before you are fully recovered may make symptoms worse and last longer and may also increase the risk of sustaining a second injury.

Following concussion biomarkers are released into saliva. These molecules, small segments of cell Ribonucleic Acid (sncRNAs), offer a potential objective way to confirm diagnosis of concussion. These biomarkers have only been studied in males, it is not yet understood if the expression of sncRNA’s is influenced by the female sex hormones.
