Prevalence of modic changes in patients with low back pain and association with degenerative spinal findings: a retrospective MRI study.

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
backgroundModic changes (MCs) are alterations in vertebral endplates visible on MRI and associated with various spinal pathologies, including disc degeneration, herniation, and spondylolisthesis. Despite their clinical significance, the associations between specific MC types and spinal pathologies require further investigation. This study aimed to investigate the prevalence and associations of MC types with demographic data and radiological findings in an Iranian population.
methodsThis retrospective cross-sectional study analyzed lumbar MRI scans from patients with low back pain. Patients with radiologically confirmed MCs met the inclusion criteria after excluding those with tumors, infections, fractures, or prior lumbar surgery. MCs were categorized into three types according to MRI signal characteristics. Associations between MC types and age, gender, disc degeneration, herniation, and spondylolisthesis were evaluated using statistical analysis.
resultsAmong 1350 patients evaluated, MCs were identified in 316 cases (23.4%), with Type 2 being the most prevalent (88.9%), followed by Type 1 (9.8%) and Type 3 (1.3%). MCs occurred most frequently at L4/L5 and L5/S1 levels. Type 1 MCs were significantly associated with younger age and disc herniation (p ≤ 0.05), while Type 2 MCs correlated with older age and moderate to severe disc degeneration (p ≤ 0.05). However, these associations did not remain statically significant after Bonferroni correction. Type 3 MCs were rare and predominantly observed in older patients. No significant gender differences in MC prevalence were observed, nor were there associations between any MC type and spondylolisthesis (P > 0.05).
conclusionsOur findings suggest that Modic changes, particularly Type 2, are common radiological findings in lumbar spine imaging, most frequently occurring at L4/L5 and L5/S1 levels. Although initial associations with disc degeneration and herniation were observed, these did not remain significant after correction for multiple comparisons. Nonetheless, the distribution and age-related patterns of Modic changes suggest their potential relevance in degenerative spinal conditions. Future longitudinal studies should investigate the clinical implications and progression of Modic changes to inform more targeted management strategies for degenerative spinal disorders.
