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	RCTs of participants who previously underwent orthodontic treatment, with subsequent crowding of the lower front teeth (lower incisors and lower canines); participants with craniofacial deformities/syndromes or serious skeletal deformities who received prior surgical/orthodontic treatment excluded	Insufficient data
Intervention	Fixed options (labial braces, lingual braces, fixed lingual wire); removable options - Hawley's retainer with active components (Hawley's retainer with spring elastomeric module, Bloore removable aligner, other modifications on the Hawley's retainer); invisible removable aligners (Invisalign, Clearstep); no active treatment	Insufficient data
Comparison	All interventions compared against each other in any combination	Insufficient data
Outcomes	Assessment of the alignment of the lower front teeth using any method or index; Aesthetic assessment by participants and practitioners; Treatment time; Patient discomfort; Quality of life; Cost-benefit consideration; Stability of the correction; Adverse effects including pain, gingivitis, enamel decalcification and root resorption	Insufficient data
Study designs	Randomised controlled trials (RCTs)	Insufficient data
Timing	Not specified	Insufficient data
