Genetically predicted DMFS (dental caries) vs Reference (1-SD lower genetically predicted DMFS)

Femur fracture · European-ancestry adults

Genetically predicted dental caries (DMFS) had no significant causal effect on fracture of femur (multivariable MR, OR 1.069).

Higher mean patient age (per 1 year) vs Lower mean patient age (per 1-year decrement)

Spontaneous space closure · Children and adolescents after extraction of a mandibular permanent first molar (before eruption of the second molar)

In the mandible, mean patient age was not significantly associated with space closure odds (OR 0.59 per year; not GRADE-rated).
