what is the claim in this passage "Only 5.3% of athletes wearing the newer helmet suffered a concussion compared to 7.3% of athletes wearing the older models . . . Overall, high school players wearing Riddel’s Revolution were 31% less likely to be diagnosed with a concussion. Table (1) shows that out of athletes sustaining their first concussion, those wearing the Revolution were able to return to game sooner than those who were wearing standard head gear. The Revolution Helmet protects the player better than standard helmets.
