Differential Effect of Vaginal Microbiota on Spontaneous Preterm Birth among Chinese Pregnant Women

Figure 2

Forest plots of vaginal bacterial traits associated with sPTB. The difference of the relative abundance of vaginal taxa between the sPTB and controls was evaluated using a zero-inflated negative binomial linear effect model. Shapes (red circles, ; orange squares, raw ; blue triangles, raw ) represent estimated coefficients, and lines show the 95% CIs of the coefficients.
