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
Adjacent vertebral fractures after balloon kyphoplasty are speculated to occur in association with increased mechanical pressure due to rigid cement-augmented vertebrae. This study aimed to clarify whether adjacent vertebral fractures are more likely to occur after balloon kyphoplasty for osteoporotic vertebral fractures when the intervening adjacent disc degeneration is advanced. We retrospectively reviewed the findings for 99 patients who underwent balloon kyphoplasty for the first-ever osteoporotic vertebral fracture at the thoracolumbar junction levels (T11-L2). Radiological parameters and clinical data were compared for the cranial and caudal vertebrae between the groups with and without adjacent vertebral fractures within 1 year postoperatively. Postoperative adjacent vertebral fractures occurred in 20 patients (12 cranial adjacent vertebral fractures and eight caudal adjacent vertebral fractures). The cranial mean disc height was 5.87 ± 1.48 mm in the cranial adjacent vertebral fracture group and 7.98 ± 1.73 mm in the non-cranial adjacent vertebral fracture group (p < 0.01), and the caudal mean disc height was 6.24 ± 1.83 mm in the caudal adjacent vertebral fracture group and 9.55 ± 2.03 mm in the non-caudal adjacent vertebral fracture group (p < 0.01). According to receiver operating characteristic analysis, the optimized cutoff values of cranial mean disc height for cranial adjacent vertebral fracture occurrence and caudal mean disc height for caudal adjacent vertebral fracture occurrence were 6.37 mm and 7.70 mm, respectively. Multiple logistic regression models showed increased odds ratios for low disc height and large cement volume for cranial adjacent vertebral fractures and low disc height and cement leakage for caudal adjacent vertebral fractures. In conclusion, patients with advanced preoperative degeneration of the adjacent disc showed a higher incidence of adjacent vertebral fracture after balloon kyphoplasty.
