In streptozotocin-injected rats (STZ-rats), a widely used experimental model for the study of diabetes-related cardiovascular complications, the extent of the vascular dysfunction depends on the duration of the pathology [ 25].
Alternatively, correlation of longer duration to pathology may result from regions being the earliest affected and therefore exposed to accumulating pathology over periods of time.
Further, comparison across previous studies is difficult due to variation in patient selection techniques, symptom duration, disability levels, and extent of pathology.
Whited [ 11] conducted a prospective study involving 200 medical and surgical intensive care unit (ICU) patients to assess the effect of duration of intubation on airway pathology.
Hamsters infected with WNV by mosquitoes or needle injections do not differ in level or duration of viremia, clinical manifestations, pathology, or antibody response (23 ).
Excluded were patients with specific LBP or non-specific LBP of less than 12 weeks duration, with cardiovascular pathology or psychiatric pathology, with any type of juridical conflict at work and/or unable to complete questionnaires in the Dutch language.
To evaluate the effect of parity, menopausal status, menstrual cycle phase, cervical or uterine pathology and duration of procedure on pain experienced during office hysteroscopy.
However, there was no significant correlation between the severity of DPR pathology and duration of disease, except weakly so in cerebellum (rs = −0.493, p = 0.027).
For example, a typical case of Achilles tendinopathy takes only 14 days to recover in our centre whereas this recovery time in a different population can be as high as several months depending on the stage of the pathology, age, duration of symptoms and occurrence of tendinopathic changes [ 35- 37].
