Effect of micro-osteoperforations on rate of space closure by mini-implant supported maxillary anterior en-masse retraction: A randomized clinical trial.
Article in Journal of oral biology and craniofacial research. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundMicro-osteoperforations is one of the non-invasive surgical techniques used in attempt to accelerate OTM. Conflicting reports on its effectiveness has been reported in the literature.
objectivesThe objectives of this trial were to investigate the effect of micro-osteoperforations on the rate of space closure and on molar anchorage loss during mini-implant supported maxillary anterior en-masse retraction. TRIAL
designA single center, parallel arm, randomized controlled trial was conducted.
methodSixty, male and female subjects (age range 16-25 years) having Class I bimaxillary protrusion or Class II div 1 malocclusion, who required fixed mechanotherapy with either upper 1st premolar or all four 1st premolar extractions were allocated into two groups using 1:1 allocation ratio. The allocation was done by block randomization method with a block size of 6. In the experimental group, 5 MOPs per side were performed only once just before the en-masse anterior retraction. Mini-screws were placed in order to obtain maximum anchorage. Impressions were taken every month till 4 months and rate of space closure was measured on 3D study models.
resultsData of 27 subjects in control (attrition = 3) and 28 subjects in experimental group (attrition = 2) were analyzed at the end of this trial. There was a statistically significant increase in the rate of en-masse retraction for the 1st month(p = 0.001,95%CI, 0.17, 0.37 mm) but there was no statistically significant difference for the subsequent 2nd (p = 0.450,95%CI,0.13,0.43 mm), 3rd(p = 0.204,95%CI,0.23,0.47 mm) and 4th month (p = 0.680,95%CI,0.21,0.41 mm) between experimental and control groups. There was also no difference (p > 0.05) in molar anchorage loss between both groups at all time intervals.
conclusionMicro-osteoperforations (MOPs) did not accelerate the rate of anterior en-masse retraction over a period of 4 months; however, it temporarily increases the rate of retraction only for first month and no affect on molar anchorage.
