World Rugby published the results this week
The summary of figures from an anti-doping report for the Rugby World Cup, contains results that are said to be inconsistent with the number of doping cases detected in other sports.
World Rugby conducted an extensive anti-doping assessment in which 200 in-competition and 268 out-of-competition samples were obtained from all 20 participating nations in the World Cup.
The 468 samples were then transferred to a reputed Anti-Doping agency in the UK for a more thorough analysis, and the number of suspicious samples detected amounted to zero.
Annual data produced by the World Anti-Doping Agency (WADA) demonstrate that between one and two percent of athletes across all sports are taking performance enhancing substances. And according to The Irish Times, the likelihood of the World Rugby report churning out no adverse results, stands at around 2%.
To put it another way, some observers believe that the report should have come back with between four and seven suspicious samples.
