Figure 6

Error-bar plot illustrating the bone level at 10 years according to the patients’ smoking status. The average (95% confidence interval) bone level was 1.60 mm (1.37; 1.83) for nonsmokers and 2.95 mm (2.32; 3.58) for smokers. Note that the 95% confidence interval of the average (represented by the error bars) does not overlap, indicating a significant difference between both groups.
