Epidemiology and Demographics

Incidence

• The incidence of diaphragmatic paralysis is unknown, but incidence of diaphragmatic paralysis after cardiac surgery is approximately 30000 to 75000 per 100,000 individuals.

Prevalence

The prevalence of diaphragmatic paralysis is unknown.

Case-fatality rate/Mortality rate

• The morbidity and mortality of the unilateral diaphragmatic paralysis is related to underlying pulmonary function and etiology.

• Most of the unilateral diaphragmatic paralysis are asymptomatic and are discovered incidentally during imaging.
• Most of the bilateral diaphragmatic paralysis are symptomatic and may develop ventilatory failure.

Age

• Patients of all age groups may develop [disease name].
• The incidence of [disease name] increases with age; the median age at diagnosis is [#] years.
• [Disease name] commonly affects individuals younger than/older than [number of years] years of age.
• [Chronic disease name] is usually first diagnosed among [age group].
• [Acute disease name] commonly affects [age group].

Race

• There is no racial predilection to [disease name].
• [Disease name] usually affects individuals of the [race 1] race. [Race 2] individuals are less likely to develop [disease name].

Gender

• [Disease name] affects men and women equally.
• [Gender 1] are more commonly affected by [disease name] than [gender 2]. The [gender 1] to [gender 2] ratio is approximately [number > 1] to 1.

Region

• The majority of [disease name] cases are reported in [geographical region].

• [Disease name] is a common/rare disease that tends to affect [patient population 1] and [patient population 2].
