Below you'll find information about how riders from Belgium performed.
For each year, it shows how many participants came from that country, how many stages these participants won together, how good their performance is according to the Mann-Whitney test (0 is very poor, 1 is very good), their score in the general classification according to max ordering (negative is poor, positive is good, 0 is average), and lexicographical ordering (0 is very poor, 1 is very good, 0.5 is average). If no participants from that country participated in a given year, this is not included in the table. Team time trials are not included in this overview.
