---|---|---|---|---|
Primary | PI ratio in the little digit | PI ratio is defined as PI at 10 minutes / PI at the baseline | 10 minutes after block | |
Secondary | PI ratio in the index digit | PI ratio is defined as PI at 10 minutes / PI at the baseline | 10 minutes after block | |
Secondary | PI values in the index digit | PI values is recorded every minute for 20 minutes then every 3 minutes for 30 minutes. | every minute for 20 minutes then every 3 minutes for 30 minutes | |
Secondary | PI values in the little digit | PI values is recorded every minute for 20 minutes then every 3 minutes for 30 minutes. | every minute for 20 minutes then every 3 minutes for 30 minutes | |
Secondary | Time needed to reach the maximum PI | PI values is recorded every minute for 20 minutes then every 3 minutes for 30 minutes. | every minute for 20 minutes then every 3 minutes for 30 minutes. | |
Secondary | Time needed to reach the maximum PI ratio | PI ratio is calculated as PI at each minute after block / PI at the baseline | every minute for 20 minutes then every 3 minutes for 30 minutes. | |
