Intestinal microbiota at engraftment and subsequent transplant course by subject (N = 80). Each row represents a study subject. Horizontal stacked bars on the left side represent the phylogenetic composition of each subject at the time of stem cell engraftment. Microbial diversity, measured by inverse Simpson index, is listed in the next column. Timeline plots are shown in the next column; black lines represent survival time, closed circles represent death, and open circles represent censoring. Red x denotes relapse or progression of disease. For death events, cause of death is listed.
