Impact of orthodontic treatment with aligners and fixed appliances on OHRQoL: a randomized clinical trial.
Trial report in Brazilian oral research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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
The aim of this study was to assess the impact of orthodontic treatment with orthodontic aligners (OAs) and fixed appliances (FAs) on oral health-related quality of life (OHRQoL). This parallel randomized clinical trial included 40 male and female patients aged 13 to 35 years diagnosed with Angle's Class I malocclusion. Participants were assigned to two groups: OA (n = 20) and FA (n = 20). OHRQoL was assessed using the Brazilian OHIP-14, which was administered before treatment (T0), at 1 month (T1), 6 months (T2), and 12 months (T3) after treatment initiation. Data were analyzed using the independent t test, the chi-square test, the Mann-Whitney test, and Friedman test (p < 0.05). FAs had a significantly (p < 0.05) higher impact on OHRQoL at T1 in terms of functional limitation, physical pain, psychological discomfort, physical disability, psychological disability, and overall score. Within-group comparison showed higher scores for the FA group in comparison to the OA group. Functional limitation scores were higher at T1 than at T0 (p = 0.034), while physical pain scores were higher at T1 compared to T0 (p = 0.034) and T2 (p = 0.010). Psychological discomfort scores were higher at T1 than at T2 (p = 0.015). Physical disability scores were higher at T1 compared to T0 (p = 0.008). Overall scores were higher at T1 than at T2 (p = 0.003). No significant changes were observed in the OA within-group comparison. Patients treated with OAs had less impact on OHRQoL compared to those treated with FAs in the first month. There was no difference between the groups at the 6-month follow-up.
