The Role of Socioeconomic Status in Longitudinal Trends of Cholera in Matlab, Bangladesh, 1993–2007
Figure 4
Mean ZIP cholera trajectories for different initial SES groups.
Line graph indicating the mean trajectory of cholera cases from the full ZIP model (Model C) for different levels of SES. These trajectories were estimated holding population constant at 40 people per bari and distance from the icddr,b hospital at 5 km. The blue lines model the trajectory of cholera for baris with low initial SES (1 SD below the mean), the black lines model cholera for baris with mean initial SES, and the red lines model cholera for baris with high initial SES (1 SD above the mean). Solid lines indicate trajectories for baris where the level of SES stays constant over the study period. Dotted lines indicate trajectory for baris where the level of SES either increases or decreases over time. The figure legend indicates how SES changes over time.
