There is a significant correlation between the Eustachian tube score - 7 and the cross-sectional size of the tympanic orifice (r  = 0.361; p = 0.022). The Eustachian tube score - 7 correlates significantly with the visualization length of complete Eustachian tube (r  = 0.436; p = 0.005) and its bony segment (r  = 0.598; p < 0.0001), respectively. The cross-sectional size of the tympanic orifice may be a specific imaging feature indicating the obstructive Eustachian tube. However, 3D morphologic measurements of the Eustachian tube are insufficient to yield useful data about its function.

However, 3D morphologic measurements of the Eustachian tube are insufficient to yield useful data about its function. This study systematically reviewed evidence from interventions on the effect of front-of-package (FOP) nutrition labeling on food purchases. The study design used in this study is a systematic review. Keyword search was performed in PubMed, Web of Science, Scopus, and Cochrane Library. Fifteen studies (10 randomized controlled trials, four pre-post studies, and one case-control study) met the eligibility criteria and were included in the review. Five studies were conducted in a controlled setting through the establishment of an online virtual supermarket or physical laboratory food store solely for the intervention. In contrast, the remaining ten studies were conducted in a naturalistic setting where people commonly purchase foods (e.g., supermarket, grocery store, school/hospital cafeteria, or vending machine). FOP labels assessed included traffic lights, health star rating, daily intake guides, health warnings, and high sugar symbol labels. Compared with the control, FOP labels were effective for hepulation subgroup, and shopping environment.It is s
