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
Background: Osteoid osteoma often requires surgical intervention following conservative treatment failure. While traditional radiofrequency ablation (RFA) is effective, poor prognostic factors such as tumor size, anatomical location, patient age, sex, and previous interventions may negatively influence outcomes. Cone Beam Computed Tomography (CBCT)-navigated RFA could mitigate these negative predictors by enhancing procedural accuracy; however, its specific impact on these factors remains under-investigated. Methods: This retrospective study included 127 patients (median age 20, IQR: 16-25) undergoing CBCT-navigated RFA for osteoid osteomas from 2015 to 2021. Outcomes assessed were treatment failure, recurrence rates, pain relief (Visual Analog Scale [VAS]), functional improvement (Eastern Cooperative Oncology Group [ECOG] status), and postoperative complications classified by the Society of Interventional Radiology (SIR) criteria. Multivariate logistic regression and statistical analyses were conducted to evaluate the influence of previously identified poor prognostic factors on outcomes. Results: Significant long-term pain relief occurred in 97 % of patients, with median VAS scores improving from 9 to 0 postoperatively (p < 0.01). Median ECOG scores improved significantly from 1 to 0 (p < 0.01). Overall treatment failure was observed in 11(8.7 %) patients, including symptomatic recurrence (4, 3.1 %), minor peripheral nerve complaints (3, 2.36 %), limited range of motion (3, 2.36 %), and Metatarsal Fracture (1, 0.8 %). Adult age was the only factor significantly associated with treatment failure (OR = 1.117, p = 0.036), whereas tumor size, anatomical location, biological sex, and prior interventions showed no significant associations. Conclusions: CBCT-navigated RFA effectively reduces the negative impact of traditionally poor prognostic factors, achieving high success rates with minimal complications. While older age remains a modest predictor of poorer outcomes, the absence of significant associations with other previously identified risk factors underscores the enhanced precision and clinical value of CBCT navigation.
