marginally significantP = 0.05
If the outlier with a value of more than 400 μm for the length of DM with an extended transitional zone tissue was dropped from the analysis, the association between the TZ-DM-tissue length and the length of DM covered with HHBs was marginally significant (beta = –0.28, B = –0.07, 95% CI = –0.14 to 0.000, P = 0.05).
