Primary school-based interventions (one or more of: school health policy, oral health education, healthy school environment, access to oral health services, community involvement) vs usual practice

Dental caries · Primary school children (aged 3-16 years) attending primary school in low- and middle-income countries (LMICs)

Among children aged 6-8 years, DMFT scores were significantly reduced (SMD -0.11); subgroup not separately GRADE-rated.

Annual increment in DMFS (D3) · Primary school children (aged 3-16 years) attending primary school in low- and middle-income countries (LMICs)

Oral-health-education interventions significantly reduced net increment in DMFS (SMD -1.05); no significant subgroup difference vs other interventions (P=0.74).

Caries increment, tooth index D(M)FT · Primary school children (aged 3-16 years) attending primary school in low- and middle-income countries (LMICs)

Among children aged 5-8 years, net increment in DMFT was not significantly reduced (SMD -0.36); no significant subgroup difference by age.

Oral methotrexate and oral prednisone vs prednisone or placebo

Primary outcome: Global improvement of disease activity or damage assessed by a medical practitioner or by participants · children and adolescents with active morphea (linear scleroderma, generalised morphea and mixed subtype: linear and circumscribed).

Oral methotrexate and oral prednisone may leads to higher primary outcome: Global improvement of disease activity or damage… compared with placebo and oral prednisone (low certainty).
