Not applicable (single-group prevalence) vs Not applicable (single-group prevalence)

Proportion of ancient skulls with at least one non-carious cervical lesion (NCCL) · Ancient/prehistoric human skulls (excavated/archaeological skeletal remains)

About 1.4% of ancient skulls (pooled) had at least one NCCL; crude 17/805 (2.11%) across 6 studies (ungraded, substantial heterogeneity I2=69%).
