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 evaluate the clinical efficacy of the simple taper-retained external connection narrow-diameter implant JUST J1 MINI (J1 implant) applied in the narrow alveolar ridge of the premolar region for 5-8 years.
methodsSixty-six patients who attended the Department of Stomatology of the Fourth Affiliated Hospital of Nanchang University for implant restoration in the premolar region from January 2017 to March 2020 were selected. A total of 87 simple taper-retained external connection narrow-diameter implants were implanted into the narrow alveolar ridge of the premolar region in the immediate postoperative period after implantation without any bone augmentation surgery. CBCT and surface tomography films were taken after the completion of final crown restoration and at the time of final follow-up. With a mean follow-up of 78.9±9.0 months, the survival rate of the J1 implants, rate of abutment loosening and shedding, amount of bone resorption at peri-implant margins, and changes in the bone width and height of the implants were observed.
resultsAt the final follow-up of 5-8 years, two implants failed when they loosened at three and four months after surgery, and the implant survival rate was 97.7%. The bone resorption values of the distal and mesial margins were 0.719 mm±0.495 mm and 0.722 mm± 0.604 mm, respectively. The bone height and width resorption of the implants were 0.581 mm±0.346 mm, 0.209 mm±0.118 mm.
conclusionsThe results of long-term follow-up after 5-8 years showed that J1 implants in the narrow alveolar ridge of premolar teeth without bone augmentation can reduce surgical trauma, simplify implant surgery, and satisfy a certain degree of aesthetics and masticatory function in patients. Therefore, J1 implants have good long-term clinical results and expand the indications for implant restorations in the narrow alveolar ridge.
