Table 1 A comparison of demographic, clinical, and laboratory findings between bacteriuric infants with low vs. high leukocytes in urine

From: Leukocyte counts in urine reflect the risk of concomitant sepsis in bacteriuric infants: A retrospective cohort study

Variable 75 infants with 0–9 leukocytes/hpf in urine: Median: IQR*; or Percentages, 95%CI (N) 170 infants with ≥ 10 leukocytes/hpf in urine: Median: IQR*; or Percentages, 95%CI (N)
Gender (% Male) 60: 48–71 (45/75) 56: 49–64 (96/170)
Race (% Caucasian) 37:26–49 (28/75) 42: 34–50 (71/170)

Grades 4–5 VUR (%) § 3.2: 0.4–11.1 (2/62) 5.9: 2.7–10.9 (9/153)
Peripheral blood leukocyte count (cells/mm3) * 14,700: 10,720–19,230 15,300: 11,000–19,900

Positive urine bacterial nitrite (%) 20: 12–31 (15/75)† 46: 38–54 (78/170)†
Hematuria: > 5 red blood cells in urine/hpf (%) 7: 2–17 (4/57)† 33: 26–41 (51/155)†
Bacterial counts in urine culture ≥ 100,000 cfu/ml (%) ‡ 72: 60–82 (54/75)† 93: 88–96 (158/170)†
Bacteremia and/or bacterial meningitis (%) 0: 0–4 (0/75)† 7: 4–12 (12/170)†
