WebCorrelation between risk of graft-versus-host disease (GvHD) and CD3+ counts within the peripheral blood stem cell graft has recently been reported in the setting of post-transplant cyclophosphamide (PT-Cy). We aimed to investigate the benefit of the addition of a single dose of anti-T lymphocyte globulin (ATLG 5 mg/kg) to PT-Cy in this setting.

Ratio, rate, or risk? - The Lancet Infectious Diseases
WebWhen the population at risk is roughly constant, incidence is measured as: Number of new cases: Population at risk×time during which cases were ascertained Sometimes measurement of incidence is complicated by changes in the population at risk during the period when cases are ascertained, for example, through births, deaths, or migrations. Webrisk. Rate = Incident cases / Total person-time at-risk The unit for a rate is “cases per person-time.” Rates are often reported as a scaled value with a time unit relevant for the study, such as cases per 1,000 person-years, 12,000 person-months, or 365,000 person-days. Rates are favored if the rapidity with which new cases of WebMay 6, 2024 · For the calculation of incidence rates an at-risk population in a year is used as a third approach [14, 15].
