Analysis of risk variables for association with maxillary sinus mucosal thickenings: a cone-beam computed tomography-based retrospective study.

It can be further appreciated that although the OR of mucosal thickenings was significantly increased ( P < 0.05, Wald’s test) in the initial model for those cases with maximum MS height > 33.60 mm, atrophic/partially atrophic alveolar process category, and the presence of foreign materials, a confounding effect was apparent for these three covariates, as the association failed to reach statistical significance ( P > 0.05) when adjusted for confounders individually.
