of borderline significancep = 0.05
While the absence of a ceiling was only significant at the p = 0.1 level of significance in the combined model, it does stand in contrast to our previous finding in the community based study that showed, in the univariable analysis, a trend in the opposite direction of borderline significance (OR 0.79; 0.63–1.00; p = 0.05) [ 8 ].
