Evaluation of the skeletal, dental, and soft-tissue changes after the en-masse retraction of upper anterior teeth stimulated by low-intensity electrical current: a randomized controlled clinical trial.
Trial report in BMC oral health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06639204 (Evaluation of the Skeletal, Dental and Soft-tissue Changes After En-masse Retraction of the Upper Anterior Teeth Stimulated by Low-intensity Electrical Current), which is not on this map.

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
backgroundLow-intensity electrical stimulation (LIES) is one of the recent physical techniques employed to accelerate orthodontic tooth movement and reduce treatment time.
objectiveThis trial aimed to assess the effectiveness of the LIES technique in shortening the en-masse retraction time and evaluate skeletal, dental, or soft tissue changes on lateral cephalograms.
methodsYoung adult patients with a Class II division I malocclusion who visited the Department of Orthodontics at the University of Damascus Faculty of dentistry, between October 2022 and February 2023 and met specific inclusion criteria were included in this two parallel arms randomized controlled trial (RCT). The patients were randomly distributed into: the LIES group and the traditional en-masse retraction (TRAD) group. Computer-generated random numbers were used for the patient assignment. Blinding was performed only during data extraction and analysis. Mini-screws were used for anchorage during the en-masse retraction, and a force of 250 g was applied bilaterally with Nickel-Titanium springs. In the LIES group, each upper anterior tooth received a 15-20 µA electrical stimulation for five uninterrupted hours daily using an intraoral removable electrical stimulation device. The assessed outcomes were the required time for completing the en-masse retraction phase and the skeletal, dental, and soft tissue changes using lateral cephalograms at specific time points (T0: baseline; T1: before en-masse retraction; T2: end of en-masse retraction).
resultsOut of 127 patients were examined, 36 adult patients were enrolled and entered data analysis with a mean age of 20.91 ± 2.24 years. The en-masse retraction phase in the LIES group took a significantly shorter time than that in the TRAD group by a mean of 2.69 months (P < 0.001). Insignificant differences were observed between the two groups in almost all measured variables. In addition, a slight anterior rotation of the mandible was observed in both groups. A greater horizontal retraction of the apices of the upper incisors was seen in the LIES group compared to the TRAD group (P = 0.005).
conclusionsThe LIES shortened the required time for the en-masse retraction of the upper anterior teeth by approximately 30% compared to the traditional method. No significant differences between the two groups were observed in skeletal and soft tissue variables. However, a greater bodily movement of the upper incisors was noted in the LIES group. REGISTRATION: This trial was retrospectively registered in the Clinical Trials database (ID: NCT06639204) and it was first posted on 15/10/2024.
