Implant removal rate and indication
| CHP (n = 19) n (%) | SCPLE (n = 48) n (%) | Mean difference (95% CI) | Relative risk (95% CI) | p value | |
|---|---|---|---|---|---|
| Implant removal | 19 (100) | 20 (42) | 2.40 (1.72–3.35) | < 0.001 | |
| Reason implant removed | 0.695 | ||||
| Routinely or patient’s request, without irritation | 3 (16) | 5 (25) | 0.63 (0.17–2.29) | ||
| Due to irritation | 16 (84) | 15 (75) | 1.23 (0.81–1.55) | ||
| Time to implant removal (months) [mean ± SD] | 4.3 (2.2) | 13.6 (11.5) | − 9.287 (− 14.757 to 3.817) | 0.002 | |
| Status implant not removed | NP | ||||
| Not experiencing irritation | 0 | 12 (43) | |||
| Irritation, but implant removal not necessary | 0 | 6 (21) | |||
| Irritation, no request removal due to fear re-operation | 0 | 5 (18) | |||
| Irritation, considering removal | 0 | 5 (18) |
Bold values indicate statistically significant results (e.g., p < 0.05). NP statistical analyses are not possible because all CHP implants were removed
