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
Objective: To assess differences in the available posterior space for molar distal movement according to the presence and three-dimensional position of third molars. Methods: This study included 46 and 59 patients for the maxilla and mandible, respectively. The patients were assigned to third molar and no-third molar groups. Retromolar distances were measured at different vertical root levels of the second molar. The positions and axial angulations of the third molars were also examined. An independent Results: The retromolar distance was shortest at the 2 mm apical level in the maxilla and at the 10 mm apical level in the mandible. The maxillary retromolar distance of the distobuccal root was significantly longer at all apical levels in the third molar group than in the no-third molar group ( Conclusions: The available posterior space with the third molar present was significantly larger than that without the third molar in the maxilla, but was not significantly different in the mandibular posterior space.
