1 · What the graph read from 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.

Abstract

introductionOur objectives were to assess patient satisfaction and quality of life among adults via 2 validated comprehensive questionnaires and to compare patient satisfaction and status in oral health-related quality of life immediately after orthodontic treatment in patients treated with Invisalign (Align Technology, San Jose, Calif) and those who received standard bracket-based treatment.

methodsAdult patients (n = 145) treated with bracket-based or Invisalign therapy were recruited from several private practices and a university clinic. The survey comprised a combination of the Dental Impacts on Daily Living index and the Patient Satisfaction Questionnaire. This 94-question assessment focused on various dimensions of satisfaction and quality of life. Multivariate analysis of variance and the bootstrap test were applied. A reliability analysis was used to assess responses at a 6-month follow-up for a small sample of patients.

resultsFinally, 122 patients were assessed. The multivariate analysis of variance analysis showed that the eating and chewing dimension was significantly different between the 2 groups (Invisalign, 49%; bracket based, 24%; P = 0.047). No significant difference in any other satisfaction factors (all, P > 0.05) was identified. The follow-up assessment was only possible in a small sample of the bracket group; it showed adequate reliability values on the categories of oral comfort (intraclass correlation coefficient [ICC], 0.71), general performance (ICC, 0.755), situational (ICC, 0.80), and doctor-patient relationship (ICC, 0.75).

conclusionsOf the patients surveyed to assess their satisfaction and oral health-related quality of life immediately after completion of their orthodontic treatment, both the bracket-based and Invisalign treated patients had statistically similar satisfaction outcomes across all dimensions analyzed, except for eating and chewing: the Invisalign group reported more satisfaction. Patient satisfaction remained relatively similar 6 months later for the bracket-type treatment.
