Abstract: Objective To assess the efficacy of computed tomography (CT) values of lumbar spine in diagnosing osteoporosis (OP) by meta-analysis. Methods PubMed, Cochrane Library, Web of Science, CNKI, Wanfang and VIP Data (from the date of each database established to December, 2021) were searched for the studies regarding diagnostic accuracy of CT values of lumbar spine for OP, and the general information and the fourfold table data were extracted. The Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2) was used to evaluate the risk of bias of the included studies. Meta-analysis was performed using Review Manager 5.4 and Meta-Disc 1.4. Results According to the vertebral bodies size, the eligible 13 studies were assigned to 6 groups of L1, L2, L3, L4, L5, and the L1-L4 mean Hounsfield units (HU) values. Since only one set of data was included for L5 and the L1-L4 mean HU values, no effect size combination was performed. The pooled sensitivity, pooled specificity, and areas under curve (AUC) of summary receiver operating characteristic (SROC) for L1 were 0.75 (95% C I: 0.72-0.77), 0.72 (95% C I: 0.70-0.73), and 0.8126 respectively; these values for L2 were 0.73 (95% C I: 0.70-0.77), 0.75 (95% C I: 0.73-0.77), 0.8010, respectively; and these for L3 were 0.78(95% C I: 0.75-0.81), 0.72(95% C I: 0.70-0.74), 0.7935, respectively. The pooled sensitivity and pooled specificity for L4 were 0.76 (95% C I: 0.73-0.79) and 0.73(95% C I: 0.70-0.75), respectively. Conclusion CT value of lumbar spine has certain significance in screening OP in different populations, however, its diagnostic ability is poor, the OP diagnosis should be analyzed comprehensively combined with other inspection results.
