The influence of orthodontist change on treatment duration and outcomes in patients treated with Clark's twin block appliance followed by non-extraction fixed mechanotherapy - a retrospective cohort study.
Article in BMC oral health, 2024. 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
backgroundPost-graduate resident turnover in public and teaching hospital orthodontic clinics often leads to challenges in maintaining the same level of efficacy when a care provider changes during orthodontic treatment. This retrospective cohort study aimed to compare the duration and quality of treatment outcomes between two patient groups: the transfer group, who underwent orthodontic care from multiple residents, and the non-transfer group, whose entire treatment was overseen by a single resident.
methodsSixty-six patients were enrolled and equally divided into transfer and non-transfer groups. Orthodontic treatment in both groups was completed with Clark's twin block appliance followed by non-extraction fixed mechanotherapy. Their pre- and post-treatment dental casts and panoramic radiographs were used to evaluate the quality of treatment outcomes utilizing the American Board of Orthodontics Cast-Radiograph Evaluation (ABO-CRE) and Peer Assessment Rating (PAR) indices. Mann-Whitney U test was used to assess the treatment time and quality between the two groups.
resultsThere was an insignificant difference in the post-treatment outcomes between the two groups as evaluated by ABO-CRE (p = 0.691) and PAR (p = 0.926). The Shapiro-Wilk test revealed a non-normal distribution of the variables. In both the transfer and control groups, the mean and standard deviation of the duration of treatment were 56.12 ± 19.68 months and 35.09 ± 6.94 months, respectively.
conclusionsTransferred patients had more visits and longer treatment duration, yet treatment quality remained comparable to the control group despite the extended duration in transfers.
