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

Element	Planned (methods)	Found (results)
Population	Participants with full arch fixed orthodontic appliance(s) with molar tubes bonded to first or second permanent molars; excludes prior fixed appliance treatment, cleft lip or palate, other craniofacial syndromes, and participants requiring orthognathic surgery	Participants with fixed orthodontic appliances and bonded molar tubes; two parallel-group UK trials, n=190 (n=2)
Intervention	Any type of adhesive used to bond molar tubes (stainless steel or titanium): chemically-cured composite, light-cured composite, conventional glass ionomer, poly-acid modified composite/compomer, or resin-modified glass ionomer; bonded molar tube	Bonded molar tubes (n=2)
Comparison	Any other adhesive; cemented band to same tooth type on opposite side of same arch (split-mouth); molar bands to same tooth type in another patient group (parallel)	Molar bands (n=2)
Outcomes	First time bond (or band) failure (primary); decalcification; adverse events (illness, allergy, bad taste, mucosal trauma); damage to teeth on tube removal; length of treatment; treatment cost; time to replace tubes	First time failure at tooth level (n=2); First time failure at participant level (n=2); Decalcification (n=1); Adverse events - none identified (n=2)
Study designs	Randomised controlled trials (RCTs), including split-mouth designs	Parallel-group RCT (n=2)
Timing	Participants followed to the end of treatment	Followed to the end of treatment
