Likewise, meta‐analyses of studies reporting on 5 to 10 years of follow‐up confirmed a significant negative effect of cigarette smoking on implant survival at implant level (OR = 0.24, 95% CI 0.11; 0.51, p < 0.001) based on 12 studies, while the trend failed to reach significance at patient level, where only 4 studies with a follow‐up > 5 years could be included (OR = 0.79, 95% CI 0.11; 5.72, p = 0.82) (Figures 3 and 4 ).
