Components

-	Summary	Type	Classifier
*	Assignment was done by order of enrollment.	Inadequate random sequence generation	Factor present, Factor likely has potential to impact results, Risk of bias direction unpredictable, Moderate risk of bias
*	The investigator who assigned the treatment was aware of the assignment which was reported verbally to the participant.	Inadequate allocation concealment	Factor present, Factor likely has potential to impact results, Risk of bias direction unpredictable, Moderate risk of bias
*	Participants could discern the difference between a parachute and an empty backpack. Knowing that they have only an empty backpack might change jumping behavior which would have an unpredictable effect on the outcome.	Inadequate blinding of participants	Factor likely present, Factor likely has potential to impact results, Risk of bias direction unpredictable, Moderate risk of bias
*	Intervention deliverers could discern the difference between the parachute and the empty backback. This likely made no difference in the outcome.	Inadequate blinding of intervention deliverers	Factor likely present, Factor likely does not have potential to impact results, Risk of bias direction unpredictable, Low risk of bias
*	Although outcome determination was done with full knowledge of exposure status, it was not likely that this changed the determination of death or injury	Bias due to lack of masking for outcome determination	Factor likely present, Factor likely does not have potential to impact results, Risk of bias direction unpredictable, Low risk of bias
*	Attrition was much higher in the intervention group.	Attrition Bias	Factor likely present, Factor likely has potential to impact results, Risk of bias direction unpredictable, Moderate risk of bias
*	Study was only published in a satirical journal issue.	Reporting Bias	Factor present, Factor likely has potential to impact results, Risk of bias direction unpredictable, Moderate risk of bias
