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.

Impaired OHRQoL measured with CPQ 11-14 (quantitative synthesis / meta-analysis)
Malocclusion (DAI) probably increases the prevalence of impaired OHRQoL (CPQ 11-14) by about 15% in adolescents (RR/PR 1.15, 95% CI 1.12-1.18; moderate certainty).

Oral health-related quality of life (OHRQoL), impaired (qualitative synthesis)
Malocclusions probably have a negative effect on OHRQoL in adolescents, after adjustment for confounders (moderate certainty).

Impaired OHRQoL, qualitative synthesis: relative effect not estimable across the 13 studies (13,864 participants); moderate quality of evidence (GRADE).13 studies · 13864 participantsModerate
