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.

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
Introduction: Although percutaneous kyphoplasty (PKP) is widely recognized as an effective treatment for osteoporotic vertebral compression fractures (VCFs), there is growing concern about the risk of subsequent VCF after the procedure. Prior studies suggest that the timing between primary VCF and PKP may affect future VCF, but there are limited data evaluating this timing, and no studies use data-driven methods to derive precise thresholds. Therefore, the aim of this study was to determine (1) the optimal time interval that minimizes the risk of 2-year subsequent VCF and (2) the impact of this interval on 90-day medical complications after PKP. Methods: A retrospective cohort analysis in patients who underwent PKP for primary thoracic VCF from 2010 to 2022 was identified using a national administrative claims database. Stratum-specific likelihood ratio (SSLR) analysis was conducted to determine data-driven timing strata between primary thoracic VCF and PKP that minimized the likelihood of subsequent VCF within 2 years of the index PKP procedure. To control for confounders, multivariable regression analysis was conducted to confirm the identified data-driven association with 2-year VCF rates and compare the likelihood of various 90-day medical complications. Results: In total, 16,197 patients who underwent PKP after primary VCF were included in this study. SSLR analysis identified two timing thresholds: 0 weeks (same day cohort) and 1 to 30 weeks (Delayed cohort). The same day cohort was significantly less likely to experience 2-year subsequent VCF than was the Delayed cohort (odds ratios: 0.52; 95% confidence interval: 0.47-0.56; p<0.001). Discussion: Early PKP significantly reduces the risk of 2-year subsequent VCFs compared with delayed intervention by nearly 50%. During this preoperative period, patient optimization should be prioritized to enhance management outcomes, allowing a careful balance between timely intervention and comprehensive patient evaluation.
