Fig. 1 Changes in serum CRP concentrations in pregnant women followed in a Prenatal Care Center in Rio de Janeiro, Brazil. Fitted values were predicted using a longitudinal linear regression model between CRP and gestational age (n = 305), β = 0.121; 95% CI, 0.071 to 0.170; P < 0.001. P-value refers to maximum likelihood estimator. N refers to total number of observations, i.e. the sum of observations for each trimester. β, longitudinal linear regression coefficient; CI, confidence interval; CRP, C-reactive protein; BMI, body mass index; GA, gestational age; GL, glycemic load.

Fig. 2 Changes in serum CRP concentrations in pregnant women followed in a prenatal care center in Rio de Janeiro, Brazil, stratified for selected variables: (I) prepregnancy body mass index; (II) parity; (III) dietary glycemic load. Fitted values were predicted using a longitudinal linear regression model between CRP and gestational age for each category; β represents the gestational age coefficient of variation for women: (a) prepregnancy normal weight (n = 152; P < 0.001); (b) prepregnancy overweight (n = 87; P = 0.059); (c) prepregnancy obesity (n = 40; P = 0.008); (d) nulliparous (n = 115; P < 0.001); (e) multiparous (n = 180; P = 0.045); (f) with dietary glycemic load below median (n = 225; P < 0.001); (g) with dietary glycemic load at median or higher (n = 75; P = 0.003). P refers to maximum likelihood estimator; n refers to total number of observations (i.e., the sum of observations for each trimester). CRP, C-reactive protein; GL, glycemic load; β, longitudinal linear regression coefficients; CI, confidence interval.
