aValues are expressed as mean ± SD.
bPaired-samples Student t test with Bonferroni correction (statistical significance, P < .01).
c95% CI of the difference between before and after values.
dA measure of how the player’s team did when he was on the ice. If the player has a positive number, more goals were scored by his team when he was on the ice than allowed; if he has a negative number, his team allowed more goals than they scored when he was on the ice.
