Evidence based orthodontics
I always wonder whether we can adopt the acceleration procedures in our practice or not?
In the recent study we covered the MID and SWE in treatment duration which help us in making informed decision in our practice.
The minimal important difference (MID) is defined as the smallest difference that the patient perceives as important.
The smallest worthwhile effect (SWE) is the important change measured with the benefit-harm trade-off method.
We have done a study to evaluate the MID and SWE in orthodontic treatment duration.
We found that the MID in the treatment duration is one month for both treatment durations 12 and 24 months. A greater SWE
than the MID is required to undergo adjunctive procedures to shorten the duration, particularly for surgical procedures.

I am indebted to the team for the great work: Despina Koletsi, Aya Jourieh, Haris Khan, Fahad Abdul, Vasiliki Koretsi, Yaser Alrefaiy, Hassan Awaisi, Qamar, Saeed. Special thanks to Prof Eliadis And the Prof. Guyatt for their supervison.

To all systematic review/meta-analysis authors and everyone interested in interpreting meta-analysis,
I am sharing my latest article which provides a simple guide for trial sequential analysis (TSA).

Trial sequential analysis (TSA) has been introduced to enhance the robustness of meta-analysis. TSA is a cumulative meta-analysis method that weighs type I and II errors while estimating the effect. The present paper introduces the TSA to orthodontic clinicians and researchers using continuous data from an orthodontic systematic review.

Orthodontic systematic reviews (SRs) include studies published mostly in English than in non-English languages which may result in a language bias.

📑For Systematic review authors and researchers:
⚠️analysis results are very sensitive when very few studies are pooled (2-4 trials).
⚠️Many between-study variance methods are used in meta-analysis ( DerSimonian and Laird (DL), Paule–Mandel (PM), Restricted maximum- likelihood (REML), Hartung Knapp and Sidik Jonkman (HKSJ) methods)
The question is which is a better method to apply for MA with few studies❓
In our study, we found:
✅ Compared to DL, HKSJ method is overconservative when I2 is greater than 0% and may result in false positive findings when the heterogeneity is absent.
✅ When I2 is 0%, DL method is enogh. However, when I2 >0, sensitivity analysis using both DL and HKSJ is required.

DL is the default method in RevMan and the most common MA software packages. However, Cochrane statistical editors are developing RevMan website to allow heterogeneity methods option

I would like to than the authors Haris Khan David Normando Nikhillesh Vaiid and Carlos Flores-Mir fro their valuable contribution.

Both ChatGPT and Google Bard generated responses were rated with a high level of accuracy and completeness to the posed general orthodontic questions. However, acquiring answers was generally faster using the Google Bard model.
