Table 2 Comparison of birth weight (kg) and maternal haemoglobin levels (g/dl) according to presence or absence of malaria infection as detected by microscopy and histology

From: Diagnostic comparison of malaria infection in peripheral blood, placental blood and placental biopsies in Cameroonian parturient women

Infection classificationa Birth weight (kg) (± SD) Hb (g/dl) (± SD)
Malaria on microscopy 3.18 ± 0.54 (67)b 9.59 ± 1.87 (62)***c
Malaria on histology only 3.40 ± 0.49 (53)d 10.90 ± 1.38 (48)e
Past malaria 3.22 ± 0.52 (70)f 10.33 ± 1.29 (61)g
No malaria 3.31 ± 0.12 (116) 10.57 ± 1.67 (107)
