Elective radical (comprehensive) neck dissection vs Elective selective neck dissection

Disease-free survival · Adults with oral cavity cancer

It is very uncertain whether elective radical (comprehensive) neck dissection changes disease-free survival (new disease, progression, and mortality) compared with elective selective neck dissection (very low certainty).

Oral health education only (verbal, written, or audio-visual education) delivered by non-dental health workers vs control (no intervention/usual care/isotonic exercise)

Caries experience · Children (mean age newborn to ~5.2 years) and their parents/carers

Oral-health-education-only interventions showed at most a marginal effect on tooth-level caries (dmft SMD -0.11, 95% CI -0.21 to -0.00; 2 studies; not GRADE-rated).
