Thank you so much for your replies, they've been super reassuring and insightful about the way things work at conferences!

Hi guys, There is an upcoming conference, at which I am presenting a poster for the first time. It was a super last minute lab decision where we sort of scraped together a project by reanalyzing videos collected by another grad student for a different project - anyway. We did a quick analysis, pumped out an abstract, and hit the submit button -- just as the clock struck midnight and the deadline was past. We got the abstract in anyway, because the PI knew a guy and was able to explain our situation. Now just recently, our stats adviser noticed that our Chi-squared/DF was too high for the poisson distribution to apply appropriately and had us run the analysis again using a negative binomial distribution. This has resulted in a change of significance (turning previously significant differences into insignificant ones) for several of our results, which were mentioned in the original abstract. Turning our original submitted abstract slightly incorrect. I feel like it is a bit too late to ask to resubmit a corrected abstract - it would be unfair to other presenters, looks unprofessional, and I don't want this reflect poorly on my PI. I'm also reluctant to suggest withdrawing from the presentation, since my PI pulled strings to make it happen and again, I don't want to reflect poorly. Any advice on how to address this?? To expand, out of the whole abstract, there is only one sentence that is incorrect: "For three threatened and endangered plant species, [the weevils] walked more than they rested." (I'm paraphrasing, obvs) The new results show that there is a visible difference between walking and resting for those three plant species, but it's not a significant difference. If we're being technical, I didn't use the word "significant" in that original sentence?? But it's still misleading?? I'd really appreciate some advice!! Thanks!
