Impact of orthodontic treatment of class II division 1 malocclusion with twin block or Sander bite-jumping appliance during puberty on oral health-related quality of life and family functioning : Randomized controlled trial.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveTo investigate quality of life changes, family impacts, and predictors of successful overjet (OJ) reduction in patients treated with removable functional appliances for prominent upper front teeth. PATIENTS AND
methodsA total of 86 cases were analyzed, whose ages ranged from 11 to 13 years (median 12; 43% female). They were randomly allocated to treatment by twin block (TB) and Sander bite-jumping appliance (SBJ). OJ was measured before and after 1 year, and the Child Perceptions Questionnaire, Parental-Caregivers Perceptions Questionnaire, and Family Impact Scale were self-administered.
resultsTreatment was unsuccessful in 33% of patients (discontinued regular check-ups or OJ reduction ≤ 40%). In successfully treated individuals, there was a reduction in problems related to child emotional well-being (EW) and oral symptoms, parental EW, and family impacts (p ≤ 0.010). In unsuccessfully treated individuals, there was a reduction in problems related to child EW and social well-being (p ≤ 0.036). In the multiple logistic regression model, sex, type of appliance, and parental perception of the child's functional limitations before treatment were predictors of successful OJ reduction (p < 0.001). Success odds were 8.1 times increased with TB compared to SBJ appliance (95% confidence interval [CI] 2.4-27.6; p = 0.001), 5 times in males (95% CI 1.6-15.5; p = 0.006) and 5 times when parents observed lowered functional limitations (≤ 4) in their child (95% CI 1.5-16.4; p = 0.008).
conclusionAppliance type, sex, and parental perceptions of a child's functional limitations predicted treatment success. Both successfully and unsuccessfully treated young adolescents reported improvement in oral health-related quality of life, implying that unsuccessfully treated patients convinced themselves that it was worth being treated.
