Summary of findings table ‐ High sodium dialysate vs standard sodium dialysate

Severe dialysis dysequilibrium syndrome · patients requiring haemodialysis

It is very uncertain whether summary of findings table ‐ High sodium dialysate changes severe dialysis dysequilibrium syndrome compared with standard sodium dialysate (very low certainty).

SGLT2 inhibitors vs placebo

Hypoglycaemia requiring third‐party assistance median · people with diabetes and CKD

Sodium‐glucose co‐transporter protein 2 (SGLT2) inhibitors leads to lower hypoglycaemia requiring third‐party assistance median compared with placebo (high certainty).

wMel‐Wolbachia infected Aedes aegypti deployments vs no deployments

Prevalence of DENV infection (any severity, any phenotype)a · children and adults at risk of dengue infection

wMel‐Wolbachia infected Aedes aegypti deployments probably leads to lower prevalence of DENV infection (any severity, any phenotype)a compared with no deployments (moderate certainty).

Teledentistry (index test): dental caries diagnosis from photographs taken with DSLR or smartphone cameras; store-and-forward vs Visual or clinical examination

Sensitivity · Children and adults with primary or permanent dentition undergoing dental caries assessment

Across 13 studies, the sensitivity of teledentistry (photographic) caries diagnosis versus visual examination ranged from 48% to 98.3%; the review pooled no estimate and did not grade certainty.

  • Teledentistry accuracy for caries diagnosis: a systematic review of in-vivo studies using extra-oral photography… 2024 All outcomes
    Cross-sectional diagnostic accuracy (index test vs reference standard, in-vivo) · In-vivo: dental clinics/hospitals, schools, and a juvenile detention facility (11 countries) · Overall (studies reporting sensitivity; narrative synthesis)
    Sensitivity Overall 48% to 98.3% across 13 studies; sensitivity is lesion-stage dependent: Kohara reported <40% for initial/moderate caries (75-100% for extensive) and early enamel lesions were less sensitive
    13 studies

Fixed orthodontic treatment with fixed (multibracket) appliances (exposure) vs None (single-group prevalence/incidence estimate)

Association between orthodontic treatment duration and ICLs incidence · Patients undergoing fixed orthodontic treatment with fixed (multibracket) appliances, followed for development of new ICLs

ICLs incidence increased with longer orthodontic treatment duration (meta-regression P<.01; ungraded).

Probiotics vs placebo or control

Dental caries in children · Children and/or adolescents (<18 years) without background systemic disease

Probiotics probably make little to no difference to the number of dental caries versus control (MD -0.24 carious pieces, 95%CI -0.72 to 0.23; low certainty).
