1 · What the graph read from it

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.

Abstract

purposeTo compare intraoperative C-arm cone-beam computed tomography (CBCT) with dedicated in-house-optimized magnetic resonance imaging (MRI) protocols, including CT-like and metal artifact reduction sequences (MARS), using a novel 15-channel coil for the evaluation of fracture reduction, osteosynthesis material positioning, and the depiction of plates and screws.

methodsFifteen patients (13 men, 2 women; median age, 32 years; range, 18-65 years) with acute cranio-maxillofacial fractures underwent surgical treatment with intraoperative CBCT, followed by early postoperative MRI within 36 h. MRI protocols included 3D ultrashort echo time (UTE), slice-encoding for metal artifact correction (SEMAC), and 3D double-echo steady-state (DESS). Two independent maxillofacial surgeons performed qualitative and quantitative evaluations of fracture reduction, osteosynthesis material positioning, and implant morphology using a 5-point visual scale (5 = best; 1 = non-assessable) and dimensional measurements. Descriptive statistics were calculated, and inter-reader agreement was assessed using weighted kappa (κ) and intraclass correlation coefficients (ICC).

resultsUTE and SEMAC sequences provided excellent CT-like performance in visualizing fracture reduction and implant positioning (median 5, IQR 5-5 and 4-5, respectively), with minimal absolute differences in quantitative measurements and substantial to almost perfect inter-reader agreement (κ = 0.75-1.0; ICC = 0.89-0.99; all p < 0.001). In contrast, DESS demonstrated limited utility for assessing metallic implants due to pronounced signal voids and susceptibility artifacts.

conclusionUTE and SEMAC provide high-quality, radiation-free imaging for evaluating fracture reduction and osteosynthesis material in cranio-maxillofacial trauma. These techniques demonstrate comparable diagnostic performance to intraoperative CBCT in a postoperative setting. They may serve as a radiation-free alternative for perioperative imaging in younger patients with anticipated repeated imaging needs, pending prospective intraoperative validation.
