1. prevalence vs in- Prevalence - number of cases at a particular time
cidence Incidence - number of new cases
2. odds ratio vs rela- odds ratio: for case control studies control for disease and examine exposure
tive risk odds dz+ in exposed group/odds dz+ in unexposed
(a/b)/(c/d)
ratio is not a fraction! so the bottom number is not the total its the unaffected
relative risk: for cohort studies that control for exposures and examine who got the
disease
prob getting dz exposed/prob getting dz unexposed
a/(a+b) / c/(c+d)
3. When is an odds case-control studies
ratio used
4. RCT or Cohort study

When is a relative
risk ratio used?
5. Delayed puberty Absence of secondary sexual characteristics by age 13
in girls failure of menarche by 16
6. delayed puberty no testicular growth has occurred by age 14 or no skeletal growth spurt has
in males occurred by age 18
7. constitutional MCC of growth delay. growth lags behind others in same age but remains consis-
growth delay tent. Often there is family history
Will have delayed bone age
8. Bence-Jones pro- tubular casts with foreign body giant cell reaction
teinuria light chains are toxic to the renal tubular epithelium
occurs in MM
