A comparison of maxillary canine retraction into healed and recent extraction sites using cone beam computed tomography: a randomized clinical trial.
Trial report in The Angle orthodontist, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
objectivesTo compare maxillary canine retraction between healed and recent extraction sites by assessing movement rate, canine dentoalveolar changes, molar rotation, and anchorage loss using cone-beam computed tomography (CBCT). MATERIALS AND
methodsTwenty-eight patients (16-26 years old) who had bimaxillary protrusion and orthodontic treatment planned with extraction of first premolars were randomly distributed into two groups and treated using a straight wire appliance. In the recent group (RG), the upper first premolars were extracted 2 weeks before the initiation of canine retraction (after tooth alignment). In the healed group (HG), the upper first premolars were extracted before tooth alignment. Movement rate, canine dentoalveolar changes, molar rotation, and anchorage loss were assessed using CBCT.
resultsMovement rate, canine alveolar bone dimensions, canine rotation, and rotation and mesial movement of the first molar were not significantly different between groups (P > .05). Canine tipping was greater in RG (P = .001).
conclusionsRetracting canines into recent extraction sites compared with healed sites showed greater distal tipping of the canine with no differences in movement rate, canine alveolar bone dimensions, canine rotation, molar rotation, and anchorage loss.
