Images of giant cell tumor and chondroblastoma around the knee: retrospective analysis of 99 cases.

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: It is difficult to differentiate giant cell tumors of the bone (GCTB) from chondroblastoma around the knee based on imaging findings. This study analyzed the imaging features of these 2 diseases for better differentiation. Methods: This retrospective cross-sectional cohort study reviewed data of patients with pathologically confirmed GCTB (n=81; age 15-75 years; median age 33 years) and chondroblastoma (n=18; age 12-34 years; median age 14 years). In all, 18 imaging signs were analyzed. Results: Patients with chondroblastoma were relatively younger than those with GCTB. On imaging, lesion length was significantly (P<0.00001) smaller in chondroblastoma [range, 15.80-78.30 mm; mean ± standard deviation (SD) 34.15±18.24 mm; 95% confidence interval (CI): 24.05-44.25 mm] than in GCTB [range, 30.10-117.50 mm; mean ± SD 59.73±15.28 mm; 95% CI: 56.24-63.22 mm]. Significantly more (P<0.05) chondroblastoma lesions had calcification (76.5% Conclusions: A narrow zone of transition, intratumor calcification, lobulation, tumor transverse diameter greater than the bone diameter, maximum lesion length, consistency between the tumor and bone long axes, and edema range around the lesion >15 mm are parameters that can be used to differentiate GCTB from chondroblastoma around the knee.
