UNASSIGNED: Authors followed the PRISMA guidelines for systematic reviews and meta-analyses. The meta package in R was used to conduct the meta-analysis. The \"metaprop\" function was used to calculate the overall sensitivity estimate and 95% confidence interval. The \"metaprop.one\" function was used to calculate subgroup estimates for static and dynamic study types. The \"metareg\" function was used to conduct meta-regression analyses to explore sources of heterogeneity.
UNASSIGNED: This study includes seven articles with 1429 perforators being evaluated. The overall proportion of the sensitivities was estimated to be 0.8754 (95% CI: 0.7542; 0.9414) using a random effects model. The heterogeneity of the studies was high, as indicated by the tau^2 value of 1.2500 (95% CI: 0.4497; 8.4060) and the I^2 value of 92.6% (95% CI: 88.1%; 95.4%). The pooled sensitivity for static imaging was 0.8636 (95%CI: 0.6238-0.9603) with a tau^2 of 2.0661 and a tau of 1.4374, while the pooled sensitivity for dynamic imaging was slightly higher (p = 0.7016) at 0.8993 (95%CI: 0.7412-0.9653) with a smaller tau^2 of 0.8403 and a tau of 0.9167.
UNASSIGNED: Further studies need to confirm that SBTI is a reliable and convenient technique for detecting perforators for the pre-operative planning of free perforator flap surgeries.
■作者遵循PRISMA指南进行系统评价和荟萃分析。使用R中的meta包进行meta分析。使用“metaprop”函数计算总体敏感性估计值和95%置信区间。“metaprop。一个“函数”用于计算静态和动态研究类型的亚组估计值。使用“metareg”功能进行荟萃回归分析,以探索异质性的来源。
■这项研究包括七篇文章,其中对1429个射孔器进行了评估。使用随机效应模型估计敏感性的总比例为0.8754(95%CI:0.7542;0.9414)。研究的异质性很高,如tau^2值1.2500(95%CI:0.4497;8.4060)和I^2值92.6%(95%CI:88.1%;95.4%)所示。静态成像的合并灵敏度为0.8636(95CI:0.6238-0.9603),tau^2为2.0661,tau为1.4374,而动态成像的合并灵敏度稍高(p=0.7016),为0.8993(95CI:0.7412-0.9653),较小的tau^2为0.8403,tau为0.9167。
■进一步的研究需要确认SBTI是一种可靠且方便的技术,用于检测游离穿支皮瓣手术的术前计划。
