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
This study evaluated the efficacy and safety of IncobotulinumtoxinA 20 U for treatment of glabellar frown lines in Chinese subjects. Methods: This was a prospective, randomized, double-blind, active-controlled, phase-3 study conducted in China. Subjects with moderate to severe glabellar frown lines at maximum frown were randomized to receive IncobotulinumtoxinA (N = 336) or OnabotulinumtoxinA (N = 167). Results: For the primary efficacy endpoint at day 30, response rates at maximum frown (score "none" or "mild") on the Merz Aesthetic Scales Glabella Lines - Dynamic were comparable between IncobotulinumtoxinA (92.5%) and OnabotulinumtoxinA (95.1%) per investigator's live rating. Noninferiority of IncobotulinumtoxinA versus OnabotulinumtoxinA was successfully demonstrated, as the two-sided 95% confidence interval of -0.97% to 0.43% for the difference in Merz Aesthetic Scales-based response rates (-0.27%) lay completely above the predefined noninferiority margin of -15%. For the secondary efficacy endpoints assessed at day 30, Merz Aesthetic Scales-based response rates (score "none" or "mild") at maximum frown were similarly comparable between both groups per subject (>85%) and independent review panel (>96%) rating. Per Global Impression of Change Scales, greater than 80% of subjects and greater than 90% of investigators in both groups rated treatment results as at least "much improved" at day 30 compared with baseline. Safety profiles were consistent between groups; IncobotulinumtoxinA was well tolerated, and no new safety concerns were identified in Chinese subjects. Conclusion: IncobotulinumtoxinA 20 U is safe and effective for treatment of moderate to severe glabellar frown lines at maximum frown in Chinese subjects and is noninferior to OnabotulinumtoxinA 20 U.
