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
introductionVertebral compression fractures (VCFs) are a common manifestation of osteoporosis and are getting more common as the world's population ages. Over the years, balloon kyphoplasty (BK) has established itself as a popular treatment modality for osteoporotic VCFs. O-arm-guided navigation is one of the innovative techniques that improve safety and precision during spine surgeries. This study aims to evaluate the accuracy and safety of O-arm-assisted BK (O-BK) in the management of VCFs. MATERIAL AND
methodsThis retrospective, single-center analysis includes patients who underwent O-BK at our institution between 2018 and 2023. The main imaging modality was the O-arm O2 Surgical Imaging System (Medtronic, Dublin, Ireland). The inclusion criteria consisted of patients with acute, painful traumatic or osteoporotic VCFs involving a maximum of three lumbar or thoracic levels and presenting with localized back pain without accompanying radicular symptoms. Patients with concomitant degenerative spinal diseases relevant to their symptoms or with unstable fractures were excluded from the study. The main objectives were to evaluate operation duration, radiation exposure, and the rate of cement leakage.
resultsA total of 74 patients with 102 vertebral levels were treated. The mean age of patients was 75.4 years, with the majority being females (71.6%, 53/74). Osteoporotic fractures were the primary diagnosis in 78.4% (58/74) of patients. The mean operation time was 63.01 minutes. The mean fluoroscopy time was 36.7 seconds. The overall mean effective dose was 9.22 mSv. Cement leakages occurred in 33.3% (34/102) of treated levels, with an intraspinal leakage rate of 3.9% (4/102). No patient experienced symptomatic leakages.
conclusionsO-BK appears to be a safe and accurate minimally invasive procedure for treating VCFs, especially those associated with osteoporosis. In addition to the controlled radiation dose, the procedure's safety is demonstrated by the low incidence of intraspinal cement leakages and the absence of neurological deficits. O-arm technology's enhanced imaging and navigation precision, which enables accurate and secure treatments, is a significant advantage.
