  1. Significant growth is defined as growth of Enterobacterales in counts of ≥ 104 CFU/ml. Parity was defined as follows: nullipara = never give birth, primipara = given birth once, multipara = parity ≥ 2, grand multipara = parity ≥ 5 [18]
  2. Data differ slightly from those in Fig. 2 where data are presented for all samples
  3. Clinically significant growth is defined as growth with an Enterobacterales species in counts of ≥ 104 CFU/ml
  4. Asymptomatic bacteriuria is defined as clinically significant growth with counts of ≥ 105 CFU/ml
