Number of participants referred for surgical exposure of the PDC · Young people aged 9 to 14 years diagnosed with one or both palatally displaced permanent maxillary canines (PDC)
It is very uncertain whether double primary (canine and first molar) tooth extraction changes number of participants referred for surgical exposure of the PDC compared with single primary (canine) tooth extraction (very low certainty).

Salivary flow rate (stimulated) · Patients with anorexia nervosa aged >=12 years (mean age ~18.4; entirely female in reported data), general community-dwelling population
Stimulated salivary flow rate was significantly lower in anorexia nervosa patients than controls, but only unstimulated flow was meta-analyzed; this outcome is ungraded.
