Table 4 Multivariable* odds ratios showing the association between foetal movement variables and late stillbirth by maternal obesity

From: A better understanding of the association between maternal perception of foetal movements and late stillbirth—findings from an individual participant data meta-analysis

  Obese (> 30 kg/m2) Non-obese (≤ 30 kg/m2)
Cases, N = 114; controls, N = 323 Cases, N = 192; controls, N = 509
Combined strength and frequency of foetal movements in the last 2 weeks

 Increased frequency but not strength 0.58 (0.23, 1.47) 0.38 (0.17, 0.82)
 Decreased frequency 3.01 (1.51, 5.99) 2.30 (1.62, 3.27)
