Guillain Barré Syndrome (GBS) in an acute illness which causes muscle weakness. The paralysis starts from the lower limbs and ascends upwards. The severity of disease is graded from 1 to 5 based on the extent of disability.
Grading of Guillain Barré Syndrome
|Grade 1||Mild to moderate disability|
|Grade 2 - 3||Severe Disability|
|Grade 4 - 5||Very severe disability requiring respiratory support|
A study was undertaken to find the association between the age when the disease develops, duration of onset and severity of disability. 50 cases of GBS in each of the given age groups were studied. The results of the study are shown in the figure and the table below.
|Age of Patients||Average duration of onset of disease||Average duration of hospitalization|
|0 - 2 years||7 days||14 days|
|2 - 5 years||8 days||10 days|
|5 - 13 years||9 days||9 days|
|13 - 18 years||3 days||30 days|
|18 - 40 years||8 days||10 days|
|40 - 60 years||7 days||14 days|
|60 - 70 years||7 days||14 days|
Which of these is a possible conclusion of the study?
