Changes in quality of life induced by tooth whitening are not influenced by global self-esteem: a randomized double-blind placebo-controlled trial.
Trial report in Odontology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03380702 (Influence of Tooth Whitening on Changes in Quality of Life), which is not on this map. Cited by 5 papers.
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.

Abstract
The purpose of this paper is to investigate which elements of tooth colour are most influenced by whitening and to identify the short-term changes in satisfaction with smile aesthetics and quality of life induced by tooth whitening and the role of global self-esteem. Sixty participants were randomly assigned to a treated or a placebo group (each group N = 30). Their anterior teeth were bleached with a photo-activated whitening gel, or subjected to a placebo. Lightness, chroma and the translucency of teeth were assessed before and 1 week after the procedure using a spectrophotometer. The Self-Esteem Scale, Psychosocial Impact of Dental Aesthetics Questionnaire, the Orofacial Aesthetic Scale and the Oral Health Impact Profile were administered to subjects. Changes in colour and chroma were greater in the treated than the placebo group (3.8 ± 1.5 vs. 1.7 ± 1.5 and - 3.2 ± 1.5 vs. 0.0 ± 1.1; p < 0.001). The treated group reported increased satisfaction with appearance and a decrease in psychological and social impacts (p < 0.05). In the placebo group there was no objective change in colour but the subjects reported an increase in satisfaction and dental self-confidence, as well as a decrease in psychological impact (p < 0.05). Self-esteem did not have a moderation nor a mediation effect. In conclusion, patients are not able to accurately detect the colour change induced by tooth whitening after 1 week, but they are also largely suggestible when evaluating the changes in quality of life. Changes in quality of life induced by tooth whitening are not influenced by global self-esteem.ClinicalTrials.gov Identifier NCT03380702.
