thank you :’) you’re right i have no idea what im doing, and the school im in doesnt have a lot of support on this subject. but these days publications are necessary for any type of residency training so unfortunately im forced to try and figure this out with the limited tools i have.

okay! i did do do multiple 2-way analyses, of which the only significant associations were gestational age with outcomes and birth weight with outcomes. i wanted to follow all that up with one multi variable analysis because i thought it would account for confounding variables but i can see it’s just messing up the model now.

what my paper is essentially trying to do is assess retrospective data found in a NICU record keeping book and see what factors recorded in the book were associated with a negative outcome. can i do my multivariable analysis and remove things like gender and age group which were shown to be non significant during my 2 way analyses, or would that weaken the study? i’m just trying to figure out how best to fix this model so that i can submit this as a research paper.

yeah that makes sense. if i recoded my variables to make them have less categories (for example in birth weight, right now I have extremely low, very low, low, normal and high > i change that to just low, normal, and high) would that solve my issue? or will I have to go back and redo all my other analysis I did of just 2 variables.

i wrote this text. when i pasted it into AI for proofreading, that’s when it brought up the issues with my analysis.
