The 28 sports hoping to stay in the Olympic Games, and the five sports on the waiting list, received no assurances on Monday with the release of the report assessing their merits.
The IOC's Programme Commission published its hefty 265-page report but made no recommendations to members who will vote on the programme at the session in Singapore on July 8.
The report assessed each Olympic sport, plus squash, rugby, golf, karate and roller sports, across a range of 33 criteria agreed in Athens last year.
The criteria include global popularity, TV and media coverage, gender equity and ticket sales.
Each of the 28 sports contested at the 2004 Athens Games will be put to a vote in Singapore. Any sport failing to win a majority of votes will be dropped for the 2012 Olympics.
