Table 4 Association between practice-specific parameters (predictors) and information quality. Generalized linear modelling was performed to assess associations. Practice-specific parameters were entered simultaneously. Overall and domain-specific information quality (as outcomes) are given in the left column. Regression coefficients and 95% confidence intervals (in parentheses) are shown. Statistically significant associations are highlighted in bold
From: German dentists’ websites on periodontitis have low quality of information
