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
backgroundOrthodontic treatment offers numerous benefits, but prolonged treatment times can lead to increased costs and sequelae. Piezoelectric-assisted procedures like piezocision show promise in accelerating treatment, though their efficacy is not yet fully confirmed, nor are they widely adopted. This study aimed to evaluate the effectiveness of piezocision for orthodontic patients.
methodsA meta-analysis of 16 randomized controlled trials (RCTs) involving 371 patients was conducted to compare piezocision with conventional orthodontic treatment. Systematic searches were performed in PubMed, EMBASE, and Cochrane Library databases. Statistical analyses included mean difference (MD) with 95% confidence intervals (CI) using a random-effects model. The study protocol was registered in PROSPERO (CRD42022335350).
resultsPiezocision significantly reduced treatment duration compared to conventional methods (MD = -39.60, 95% CI -59.67 to -19.52), though total treatment time was investigated by only one research group. Posttreatment pain was significantly higher in the piezocision group on day 1 (MD = 17.83, 95% CI 5.75-29.92) but showed no significant differences on day 7 (MD = 4.86, 95% CI -0.74 to 10.47). Despite similar pain levels by day 7, patients expressed preferences for conventional orthodontic treatment. The reduction rate of Little's irregularity index was more efficient in the piezocision group during the first month (MD = 1.58, 95% CI -0.13 to 3.29), with no significant differences at the end of alignment (MD = 1.04, 95% CI -0.06 to 2.15).
conclusionPiezocision resulted in reduced orthodontic treatment duration compared to conventional methods. However, considering the study limitations and patient preferences, future research with larger sample sizes and more RCTs is needed to validate these findings and assess the long-term clinical implications before widespread adoption.
