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 investigate the pattern of change in force and moment according to the amounts of labial tipping and the material types of clear aligners (CA). Methods: A 3D-printed maxillary typodont system, including crown, root, and periodontal ligament space, was constructed. Six groups were established based on the amount of labial tipping of #12 (0.3 mm and 0.6 mm), and the material types (Zendura [thermoplastic, one-layer, 0.75 mm], Trioclear [thermoplastic, three-layer, 0.5 mm], and Graphy TA-28 [direct printing, 0.5 mm]) (n = 6/group). A six-axis mechanical sensor apparatus was connected to the roots. Force and moment were measured after seating the CA in a 37°C water bath. Results: When comparing 0.3 mm and 0.6 mm tipping, #12 showed an increase in labial inclination moment (Lab-inclination moment) in Zendura ( Conclusions: Clinicians should select the appropriate aligner material based on the specific biomechanical requirements to prevent unexpected forces and moments.
