Six‐month clinical outcomes. Multilevel model: centre, patient, tooth
| Variable | CTG N = 243 | CMX N = 242 | Estimated difference (odds ratio*) | 95% CI |
|---|---|---|---|---|
| Changes in CEJ‐GM (mm) | 2.1 (1.0) | 1.7 (1.1) | 0.44 | 0.25; 0.63 |
| Changes in IE‐GM (mm) | 2.1 (1.1) | 1.4 (1.2) | 0.63 | 0.43; 0.84 |
| Changes in PD (mm) | −0.3 (0.8) | −0.1 (0.7) | −0.18 | −0.31; −0.04 |
| Changes in KT (mm) | 0.5 (1.2) | −0.1 (1.1) | 0.47 | 0.24; 0.70 |
| Complete root coverage N (%) | 170 (70%) | 117 (48%) | 4.02* | 1.83; 8.83 |
Multilevel model estimating clinical outcomes taking into account clustering of multiple sites in a single patient (surgery) and patients within a specific study centre. Changes in CEJ‐GM = changes in the distance from the cemento‐enamel junction to the gingival margin. Changes in IE‐GM (mm) = changes in the distance between the incisal edge of the tooth and the gingival margin. They are estimates of root coverage. PD, probing depth; KT, width of keratinized tissue. Data are expressed as means (SD) in mm.
