Variables of the study.

(A) Identification of symptoms (IS)	(B) Autoinjector administration skills (AS)	(C) Administration time (AT)
Signs and symptoms that indicate presence of anaphylactic shock on cutaneous (pruritus and morbilliform rash) and respiratory (dyspnea and cough) level. Symptoms 1 (S1): number of visual fixations towards the signs and symptoms that the participant makes before using the autoinjector. Symptoms 2 (S2): number of visual fixations towards the signs and symptoms that the participant makes during the administration of the autoinjector. Symptoms 3 (S3): number of visual fixations towards the signs and symptoms that the participant makes after the administration of the autoinjector. Symptoms 1 in percentage (S1%): percentage of visual fixations towards the signs and symptoms that the participant makes before using the autoinjector. Symptoms 2 in percentage (S2%): percentage of visual fixations towards the signs and symptoms that the participant makes during the administration of the autoinjector. Symptoms 3 in percentage (S3%): percentage of visual fixations towards the signs and symptoms that the participant makes after the administration of the autoinjector.	Autoinjector error (AE): incorrect or no use of the injector. Incorrect use was considered as using the injector upside down, no removal of security cap, and/or no firing of the needle during administration. Thigh localization (TL): it was considered as a quality localization if the administration was made in the thigh musculature. Quality administration (AQ): it was considered as a quality administration if (i) the injector was prepared and used in a correct way, (ii) the injection time (IT) was equal to or greater than ten seconds, (iii) the administration was made in the thigh musculature. Efficient administration (AE): an efficient administration was recorded when, even though a quality administration was not performed, it was efficient for the patient. It was considered as an efficient administration when (i) the injector was prepared and used in a correct way, (ii) the injection time (IT) was equal to or greater than three seconds, (iii) the administration was made in the thigh musculature.	Hand time (HT): time (in seconds) from the beginning of the scenario until the participant held the injector in his or her hand. Use time (UT): time (in seconds) from the beginning of the scenario until the injection was made. Injection time (IT): time (in seconds) that the injector remained inserted in the patient's thigh to inject adrenaline.
