On the other hand, "functional status" was considered one of the major predictors of long-term outcome [36].
When vitamin D status was considered as a dichotomous variable, patients with 25OHD <20 ng/mL were more than 2.5 times more likely to have a non-home discharge destination compared to patients with 25OHD ≥20 ng/mL (OR, 2.74; 95 % CI 1.23 6.14).
For the remaining patients, their vital status was considered alive.
Normoalbuminuria required that all urinary albumin measurements were within the normal range, otherwise the albuminuria status was considered unknown.
Obesity status was considered as a separate factor with obesity defined as body mass index (BMI) greater than or equal to 30 [27].
In this study, age, oesophageal cancer status, and sex were included to improve model fitting; cancer status was considered to be primary binary, i.e., 0 for no oesophageal cancer and 1 for cancer, and sex-code was fitted as a covariate to a primary trait, i.e., 0 for male and 1 for female.
HIV status was considered undetermined otherwise.
DNAm status was considered to change according to the immortalization.
ER/PR-positive status was considered as more than 5% staining in cell nuclei; otherwise, ER and/or PR status was considered as negative.
The ER status was considered positive in cancers with more than 10% nuclear staining.
Self-reported vaccination status was considered sufficient in those individuals whose GP could not be contacted.
