The cited 2001 paper is titled "Atrophic rhinitis: a review of 242 cases", not a case study of 242 secondary-atrophic-rhinitis patients. Its abstract states that the cohort consisted of patients with atrophic rhinitis generally, and that patients were then classified as primary if the condition developed in a previously healthy nose and secondary if it developed after sinonasal surgery, trauma, or chronic granulomatous disease. That directly contradicts the Wikipedia sentence, which says the paper was a case study of 242 people with secondary atrophic rhinitis.

So there are two concrete errors in the quoted sentence:

1. it misstates the paper type (review of cases vs. “case study”), and
2. it misstates the study population (242 atrophic-rhinitis cases overall, not 242 secondary cases).

This clause incorrectly describes the International Rhinologic Society meeting schedule as a once-every-four-years event. Official American Rhinologic Society coverage of Nose 2000 states that the next meeting of the International Rhinologic Society would be held in 2003, which is only three years later. The current official IRS meetings page also lists events in 2019, 2022, and 2024, which again are not separated by four-year intervals.

So the problem is not that Nose 2000 did not happen; it did. The error is the claim that the meeting "occurs every four years." Official society materials contradict that schedule.
