Independent risk factors for specific complications

Factor	Complication	β	SE	P-value	95% CI
VP shunting after cranioplasty	Implant dislocation	0.36	0.07	< 0.001	0.14 – 0.4
Seize of bone graft	Osteolysis	0.001	0.05	0.001	0.23 – 0.02
Location of cranioplasty	Infection	0.18	0.03	0.04	0.01 – 0.1

P-value was calculated by using multiple linear stepwise regression with the respective significant results of the bivariate analysis as well as the possible confounders of the individual complications. All regressions included demography, comorbidities, primary diagnosis and mediation
