Diagnostic performance of zero-echo time (ZTE) MRI for preoperative evaluation of cervical OPLL complicated with dural ossification (DO): a retrospective study.
Article in Skeletal radiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveTo evaluate the diagnostic efficacy of zero-echo time (ZTE) magnetic resonance imaging (MRI) for cervical ossification of the posterior longitudinal ligament (OPLL) complicated by dural ossification (DO), compared with T1-weighted imaging (T1WI) and T2-weighted imaging (T2WI). MATERIALS AND
methodsThis retrospective single-center study included 73 consecutive OPLL patients (52 males, 21 females; mean age 55.5 ± 10.6 years) admitted between April 2025 and October 2025. All underwent 1-mm thin-slice computed tomography (CT) (gold standard) and 3.0T MRI (T1WI, T2WI, and ZTE). Two senior radiologists blindly assessed DO presence. Sensitivity, specificity, diagnostic accuracy, area under the curve (AUC), and Cohen's κ interobserver agreement coefficient were calculated, with McNemar's and DeLong's tests applied for interreader and pairwise AUC statistical comparisons, respectively.
resultsCT confirmed 46 cases (63.0%) of cervical OPLL complicated with DO. For the ZTE sequence, the diagnostic sensitivity of the two readers was 93.5% and 95.7%, specificity was 96.3% and 88.9%, accuracy was 94.5% and 93.2%, and AUC was 0.949 and 0.923, respectively. These metrics were significantly superior to those of T1WI imaging (AUC 0.522-0.536) and T2WI imaging (AUC 0.550-0.572). DeLong's test confirmed that the AUC of ZTE was significantly higher than that of T1WI (P < 0.001) and T2WI (p < 0.001), while there was no significant difference between T1WI and T2WI (p > 0.05). Regarding interobserver consistency: the Cohen's κ value for ZTE was 0.854, while those for T1WI and T2WI were -0.043 and 0.466, respectively.
conclusionZTE-MR imaging offers a nonionizing, highly sensitive, and reproducible approach for diagnosing cervical OPLL with DO and serves as a valuable adjunct to conventional sequences for preoperative evaluation.
