All vascular LLAs (at or proximal to the transmetatarsal level) performed from 1997 through 2006 were consecutively registered and classified into initial unilateral amputation, contralateral amputation, or reamputation.
In order to achieve balanced study groups, we consecutively selected pre-classified samples for each stage (Table 1) from the tissue bank.
Here, the sequence of TESTS paired consecutively as CXR and LP, LP and UA, and UA and abdominal CT are unannotated in the dataset with a relation, but the identification classifier classifies them as having a relation.

Study group allocation concealment was classified as: adequate (i) if a method such as consecutively numbered sealed opaque envelopes was used; unclear (ii) if the concealment technique was not described; or inadequate (iii) if there was an open list of random numbers or no random assignment (e.g. QE) was used.
Household income reflected monthly income and was divided into 6 categories (<950 euro, 950 1300 euro, 1300 1900 euro, 1900 3150 euro, 3150 3500 euro, and 3500 euro and more) being consecutively adjusted for the number of persons in the household and classified into 1) minimum; 2) minimum-moderate; 3) moderate-2× moderate; and 4) >2× moderate.
In this cross-sectional study, patients with their pain classified according to its etiology (chronic/idiopathic, nociceptive and neuropathic pain) were consecutively recruited for self-assessment of their actual pain intensity using a continuous VAS, 0 100, and a discrete five-category VRS.
