No significant difference in kaposi's sarcoma between ART regimens (very low certainty).

1 finding from 1 review

Food and nonalcoholic beverage marketing (exposure) vs No, less, or less powerful food marketing

Food purchasing · Children and adolescents (general population, aged under 20 years)

Food marketing showed no clear association with food purchasing by or for children (very low certainty).

1 finding from 1 review

Antiretroviral therapy (any, including cART) vs No antiretroviral medication (treatment-naive)

Oral candidiasis prevalence · Children and adolescents (<18 years) living with HIV (CLWH)

ART was associated with lower oral candidiasis prevalence.

Responsive complementary feeding (RCF) / other caregivers' feeding practices vs Other models of complementary feeding (traditional/non-responsive CF)

Hypertension (later in life) · Healthy, term-born, normal-birth-weight infants aged 4-24 months (breastfed and/or formula-fed) in Western industrialized countries

No eligible studies examined the influence of complementary feeding practices on later hypertension; this is an evidence gap.

Ion-releasing restoration (glass ionomer-based and compomer/polyacid-modified composite) vs Resin composite restoration

Secondary caries (caries around restorations), load-bearing cavities · Patients with permanent dentition in need of restorations in load-bearing cavities (Class I/II posterior)

In load-bearing cavities, ion-releasing (GIC and compomer) and resin composite restorations show no significant difference in secondary caries (RD -0.00, 95% CI -0.01 to 0.01; not GRADE-rated).

1 finding from 1 review

Fluoride-free nano-hydroxyapatite (nHA) dentifrice/paste vs Sodium fluoride (control) toothpaste

Mineral loss (transversal microradiography) · Enamel/dentin specimens with initial caries lesions (or sound surfaces) in intraoral (in situ) appliances worn by patients

Under demineralizing conditions, nHA allowed significantly more enamel demineralization than NaF (MD 1625, 95% CI 553 to 2697; very low certainty).
