Ungraded means an effect was reported without a GRADE rating; it is not a gap. No studies means the review found nothing to answer the question. The six categories are a display order, not a score.

Review question

ElementPlanned (methods)Found (results)
PopulationEdentulous adult patients requiring complete denturesEdentulous adults requiring complete dentures (n=30)
InterventionInterventions comparing different posterior occlusal schemes (e.g. anatomic teeth, non-anatomic teeth, zero-degree teeth) in the construction of complete denturesLingualised teeth (maxillary anatomic + mandibular non-anatomic; lingualised occlusion) (n=30)
ComparisonA different posterior occlusal scheme (head-to-head comparison of schemes)Zero-degree teeth (non-anatomic, cuspless) (n=30)
OutcomesPatient perceived satisfaction (primary); Patient perceived comfort; Patient perceived masticatory/chewing function; Patient perceived masticatory/chewing efficiencyPatient preference/satisfaction (n=30); Number of adjustments required (n=30)
Study designsRandomised or quasi-randomised controlled clinical trials (RCTs)1 cross-over RCT (Clough 1983); judged high risk of bias (insufficient information on randomisation and allocation concealment)
TimingStudies to be grouped according to treatment type and duration of follow up3 weeks per denture set (cross-over)
