Table 5B Validity of GA weeks data comparing ultrasound to HDSS and to EN-INDEPTH survey (Matlab, n = 481)

From: Gestational age data completeness, quality and validity in population-based surveys: EN-INDEPTH study

Panel A: Baby’s maturity—HDSS compared to ultrasound (gold standard)

  

Ultrasound

 

Sensitivity (HDSS) = 65.7%

Specificity (HDSS) = 94.5%

Positive predictive value (HDSS) = 74.6%

Negative predictive value (HDSS) = 96.4%

Kappa [CI] = 0.65 [0.55, 0.76]
