Table 3 Comparison of pooled diagnostic performance of D-dimer and fibrinogen by Z-test statistics

From: Fibrinogen performs better than D-dimer for the diagnosis of periprosthetic joint infection: a meta-analysis of diagnostic trials

  D-dimer Fibrinogen Z value p value
Pooled value SE 95% CI Pooled value SE 95% CI
Sensitivity 0.79 0.04 0.72–0.85 0.75 0.03 0.68–0.80 1.02 0.15
Specificity 0.77 0.04 0.67–0.84 0.85 0.01 0.82–0.88 1.93 0.03*
LR+ 3.38 0.74 2.21–5.18 5.12 0.51 4.22–6.22 1.94 0.03*
LR− 0.27 0.06 0.18–0.41 0.30 0.04 0.23–0.37 0.42 0.34
  1. SE standard error, CI confidence interval, LR+ positive likelihood ratio, LR− negative likelihood ratio
  2. *p value less than 0.05 meant significant difference
