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
purposeImplant-related complications can occur after the surgery for adolescent idiopathic scoliosis (AIS) and remain untreated for long periods until they become painful enough for intervention. This can result in a rigid deformity with vertebral fusion and disc degeneration within the scoliotic curve. This report aimed to emphasize the importance of early revision surgery illustrated in three unique cases. CASE DESCRIPTION: The cases presented were as follows: a 48-year-old female who had experienced implant failure following posterior corrective fixation left untreated for 25 years; a 32-year-old female who had experienced implant failure following anterior corrective fixation left untreated for 16 years; and a 23-year-old male who had experienced pseudarthrosis following posterior corrective fixation and had been left untreated for 5 years following implant removal. All patients exhibited vertebral fusion and disc degeneration within the exacerbated major thoracolumbar/lumbar scoliotic curve as well as kyphotic deformity because of prolonged neglect after implant failure. In all cases, surgery required an anteroposterior combined procedure with anterior intervertebral release, posterior fusion mass osteotomy, and asymmetric pedicle subtraction osteotomy.
conclusionWhen implant failure occurs after AIS surgery, early surgical intervention can enable less extensive revision with reduced risk before stiffness and fusion of the bone mass develop. Regular long-term follow-up is therefore essential for early detection of implant failure. Moreover, when recommending revision surgery, it is critical to intervene at an appropriate time, ensuring that patients fully understand both the risks and benefits, including the psychological burden of residual deformity.
