Article in Medical science monitor : international medical journal of experimental and clinical research, 2023. 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
BACKGROUND Modic changes (MC) are abnormal bone signals under the vertebral endplates on magnetic resonance imaging (MRI) of the spine. Three types of MC may be seen on MRI as abnormal bone signals of the vertebral endplate and adjacent bone marrow. This retrospective study of 203 patients with symptomatic cervical ossification of the posterior longitudinal ligament (OPLL) aimed to evaluate factors associated with MC on cervical spine MRI. MATERIAL AND METHODS We included 203 patients with symptomatic cervical ossification of the OPLL. All patients underwent MRI with T1 and T2 sequences to assess the presence and type of MC. Univariate and multivariate logistic regression analyses were used to identify the risk factors for MC. RESULTS The prevalence of MC in patients with symptomatic cervical OPLL was 21.18%. Type 2 MC accounted for 88.64% of the cases. Local type and MC share the same segment (100.00%), followed by segmental type (77.27%), mixed type (75.00%), and continuous type (75.00%). Age (OR=1.05, 95% CI: 1.01-1.09, P=0.013) and neck pain (OR=2.67, 95% CI: 1.04-6.83, P=0.041) were significantly correlated with MC. Further receiver operating characteristic (ROC) analysis displayed an area under the curve (AUC) of 0.657 (P=0.002) for age, and the optimal cutoff was 60.50 years (sensitivity 0.67, specificity 0.68). CONCLUSIONS The results of this study found that older age and neck pain were significantly associated with development of cervical spine MC. Patients ≥60.5 years with symptomatic cervical OPLL had a higher probability of developing MC.
