Ummm....24,000 players studied, 12 times higher?
Any statisticians out there?
Statistically significant, to say the least. Assuming, of course, that the methodology is as sound as claimed.... I was rather surprised to see Dr. Chiò actually defending the methodology, as if he expected to be attacked on that front.
It says 7000 players, with 18 cases of the disease.
I played soccer all my life, including as an adult for over 10 years at a high competitive level, approximately 30 matches a year, practices, etc.
I always felt, the day after a match, like I had been beaten with a stick over every square inch of my body.
There are special muscles used in soccer (interior of thighs, adductors/abductors) that aren't used to any similar degree in other sports, at least sports I've played.
Anyone who'se played knows the physical difference between endurance training by running, versus a real soccer workout. The former can never fully prepare you for the latter -- only by playing soccer can you build up those muscles.
Just some thoughts....
12 times higher = 18 total, easily small enough of a number for it to be a coincidence.

Supposedly, ALS affects 1 in 100,000.
