^*p vs non-MDC

^**Specific values for cells <11 have been censored along with other cells that may make such cells calculable

MDC = multidisciplinary care, all patients receiving multidisciplinary care (includes patients receiving MDC on same date, and different dates). MDC_SD = same-day multidisciplinary care. SD = standard deviation. Cens = census-derived
