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
backgroundPreoperative adjacent disc height (DH) was found as an independent risk factor for adjacent segment degeneration (ASD) after percutaneous kyphoplasty (PKP), indicating the preoperative status of the adjacent intervertebral discs may be closely related to adjacent segment complications. To establish the reference intervals (RIs) for adjacent DH of fresh osteoporotic vertebral compression fracture (OVCF) in Chinese postmenopausal women, and investigate the association with adjacent segment complications after PKP.
methodsConsecutive inpatients diagnosed with fresh OVCF between November 2015 and August 2023 were reviewed. The enrolled patients were divided into subgroups based on injured vertebral level; then, the cranial and caudal DH were measured. The characteristics of DH among subgroups were identified, and specific RIs were established using the indirect Hoffmann method. The associations between DH and adjacent segment complications were assessed using multivariate analysis.
resultsThe DH of the cranial disc was significantly lower than the corresponding caudal disc in all vertebral levels, which showed an increasing trend from T11 to L4. The RIs of DH were as follows: T11 (cranial), 2.14-5.14 mm; T11 (caudal), 2.64-5.89 mm; T12 (cranial), 2.69-5.77 mm; T12 (caudal), 3.18-6.57 mm; L1 (cranial), 3.05-6.59 mm; L1 (caudal), 3.40-8.29 mm; L2 (cranial), 3.68-8.36 mm; L2 (caudal), 4.57-9.78 mm; L3 (cranial), 4.53-8.92 mm; L3 (caudal), 5.26-10.07 mm; L4 (cranial), 4.70-11.42 mm; and L4 (caudal), 5.52-12.12 mm. Increased risks of adjacent segment complications after PKP were observed in patients with decreased adjacent DH.
conclusionThe estimated vertebral level and disc level-specific RIs for adjacent DH of fresh OVCF were established in the Chinese postmenopausal women population. A decrease in adjacent DH posed high risks of adjacent segment complications after PKP for treating OVCF.
