Summary of findings: Low‐moderate GI diet vs moderate‐high GI diet (maternal outcomes)

Eclampsia · pregnant women with GDM

It is very uncertain whether summary of findings: Low‐moderate GI diet changes hypertensive disorders of pregnancy: eclampsia compared with moderate‐high GI diet (maternal outcomes) (very low certainty).

Summary of findings: Low‐moderate GI diet vs moderate‐high GI diet (neonatal/child/adulthood outcomes)

Large‐for‐gestational age · pregnant women with GDM

Summary of findings: Low‐moderate GI diet showed no clear difference in large‐for‐gestational age compared with moderate‐high GI diet (neonatal/child/adulthood outcomes) (low certainty).

Lower family socioeconomic status / income vs Higher socioeconomic position

Dental caries · Healthy children and adolescents in the United Arab Emirates

Evidence on socioeconomic status/income and caries was inconsistent: some studies linked lower income to higher caries while others found no association (narrative synthesis; not GRADE-rated).

Low tooth brushing frequency (<2 times/day) vs High tooth brushing frequency (>=2 times/day)

Early childhood caries (ECC) · Healthy children under 6 years of age (6 months to 6 years); preschool children

After excluding an extreme outlier (Alhabdan 2018), the association between low brushing frequency and ECC remained statistically significant (pooled OR approximately 2.0, p=0.003; I2=87.5%); the exact estimate and its CI were not reported; ungraded.

Lower parental (maternal/paternal) education vs Higher parental education

Dental caries · Healthy children and adolescents in the United Arab Emirates

The association between parental education and caries was inconsistent; father's (but not consistently mother's) education was inversely associated with caries in some studies (narrative synthesis; not GRADE-rated).

Low maternal education (<=6 years of schooling) vs Higher maternal education (>6 years)

Poor oral health-related quality of life (OHRQoL) · Children aged 3-12 years

Lower maternal education was associated with poor OHRQoL (OR 1.12, 95% CI 1.00-1.23; 4 studies; high heterogeneity; CI lower bound at the null; ungraded).

Fluoride toothpaste 440 ppm (lower concentration) vs 1450 to 1500 ppm F toothpaste

Fluorosis (percentage prevalence in permanent teeth) · Children exposed to topical fluoride when under 6 years old; fluorosis assessed in permanent teeth at 6 to 18 years

Fluoride toothpaste 440 ppm (lower concentration) probably leads to lower fluorosis (percentage prevalence in permanent teeth) compared with fluoride toothpaste 1450 ppm (higher concentration) (moderate certainty).
