Fig 1.
Distribution of preceding birth interval by survival status for urban areas in Bangladesh.
Fig 2.
Distribution of preceding birth interval by survival status for rural areas in Bangladesh.
Figs 1 and 2 display simple bar diagrams representing percentage frequencies of births intervals. The bars A, B, C, and D stand for the birth intervals of less or equal to 35 months, 36-59 months, 60-119 months, and greater or equal 120 months, respectively. The left and right sided diagrams in Figs 1 and 2 appear for event and censored cases.
