What's the difference between incidence and incidency?

Incidence


Definition:

  • (n.) A falling on or upon; an incident; an event.
  • (n.) The direction in which a body, or a ray of light or heat, falls on any surface.

Example Sentences:

  • (1) By 1978, the reduction in incidence of measles will exceed 90%.
  • (2) The cumulative incidence of grade II and III acute GVHD in the 'low dose' cyclosporin group was 42% compared to 51% in the 'standard dose' group (P = 0.60).
  • (3) Children of smoking mothers had an 18.0 per cent cumulative incidence of post-infancy wheezing through 10 years of age, compared with 16.2 per cent among children of nonsmoking mothers (risk ratio 1.11, 95% CI: 1.02, 1.21).
  • (4) In X-irradiated litters, almost invariably, the incidence of anophthalmia was higher in exencephalic than in nonexencephalic embryos and the ratio of these incidences (relative risk) decreased toward 1 with increasing dose.
  • (5) A commensurate rise in both smoking and adenocarcinoma has occurred in the Far East where the incidence rate (40%) is twice that of North America or Europe.
  • (6) Side effect incidence in patients treated with the paracetamol-sobrerol combination (3.7%) was significantly lower than that observed in subjects treated with paracetamol (6.1% - P less than 0.01), salicylics (25.1% - P less than 0.001), pyrazolics (12.6% - P less than 0.001), propionics (20.3%, P less than 0.001) or other antipyretics (17.9% - P less than 0.001).
  • (7) Time-series analysis and multiple-regression modeling procedures were used to characterize changes in the overall incidence rate over the study period and to describe the contribution of additional measures to the dynamics of the incidence rates.
  • (8) Factors associated with higher incidence of rejection included loose sutures, traumatic wound dehiscence, and grafts larger than 8.5 mm.
  • (9) In a random sample of 1,000 neonates from a Delhi Hospital the incidence of jaundice was 53% and of hyperbilirubinaemia (HB) 6%.
  • (10) Peak incidence is found among 40 to 49-year-old and 60 to 64-year-old women.
  • (11) The high incidence of infant astigmatism has implications for critical periods in human visual development and for infant acuity.
  • (12) In all, 207 cases of liver cancer were seen during this period, giving an incidence of rupture of 14.5%.
  • (13) Serial observations of blood pressure after unilateral adrenalectomy for aldosterone-producing adenoma revealed an incidence of hypotension (systolic BP less than fifth percentile for age- and sex-matched normal population) of 27% at 2 years, more than 5 times that predicted.
  • (14) He also deals with the incidence, conservative and surgical treatment of osteo-arthrosis in old age and with the possibilities of its prevention.
  • (15) We have not had another incidence of fetal scalp infection associated with intrapartum monitoring.
  • (16) The most important conclusion of both conferences was that oestrogen substitution can significantly reduce the incidence of fractures in postmenopausal women.
  • (17) We investigated the incidence of skin cancer among patients who received high doses of PUVA to see whether such incidence increased.
  • (18) In addition, recent increase of the annual incidence of the above both groups was clarified.
  • (19) We found that, although controlled release delivery of ddC inhibited de novo FeLV-FAIDS replication and delayed onset of viremia when therapy was discontinued (after 3 weeks), an equivalent incidence and level of viremia were established rapidly in both ddC-treated and control cats.
  • (20) We studied the effect of low-dose intrathecal morphine (0.00-0.20 mg) on pain relief and the incidence of side effects after cholecystectomy in 139 patients divided into eight groups according to intrathecal morphine dose: groups 1 (0.00 mg), 2 (0.04 mg), 3 (0.06 mg), 4 (0.08 mg), 5 (0.10 mg), 6 (0.12 mg), 7 (0.15 mg), and 8 (0.20 mg).
