Comparison of brainstem structural volumes relative to the whole brainstem between problematic smartphone users and control group

PSU (n=20) TDC (n=67) F p-value
Midbrain, mm3 5888.10±552.43 6113.17±602.11 0.427 0.516
Pons, mm3 13886.58±1843.35 14062.45±1621.91 0.855 0.358
SCP, mm3 225.12±38.40 250.92±47.45 8.273 0.005**
Medulla, mm3 4197.19±502.27 4280.14±434.98 0.053 0.819
Whole brainstem, mm3 24196.98±2805.58 24706.68±2517.65 0.019 0.892

** p<0.01. Analysis of covariance was performed on the volume comparison with age, sex, BSCS, and BDI as covariates. PSU, problematic smartphone use; TDC, typically developing children; SCP, superior cerebellar peduncle; BSCS, Brief Self Control Scale; BDI, Beck Depression Index
