The extent to which the association between age at menarche and HSV-2 or HIV could be explained by measured behavioural and socio-economic factors was explored in multi-variable analyses, including these factors in the models, as appropriate.
In relation to the other lymph node parameters, total number of lymph nodes retrieved and total number of negative lymph nodes did not influence overall survival in either colon or rectal cancers, whereas the remaining lymph node variables analysed, including N stage, achieved statistical significance (Table 3).
Variables analysed included age, diagnosis, ICU admission, time spent by CCOS, interventions provided and in-hospital mortality.
Variables analysed include tumour size, histological subtypes, tumour grade, tumour stage, ER and Her-2/neu status.
Variables analysed included tumour grade, axillary nodal status and ER status.
The variables analysed included duration of eating and rumination, number of chewing cycles during eating and rumination, number of regurgitated cuds and number of chewing cycles per cud.
The variables analysed included age, gender, BMI, tumour location, distant metastases, nodal metastases, invasion through the muscularis propria, tumour-destructing peritumoural inflammatory infiltrate and necrosis.
The categorical variables analysed included sex, antibiotics received at admission, patient origin, diagnostic category at admission, trauma patients (with or without surgical intervention), immunodeficiency, invasive devices and in-hospital death.
The variables analysed included the agent, setting of the outbreak, date of appearance of the first case, number of people exposed, number of cases, age, sex, symptoms and hospitalization.
Lipid variables analysed included TC, TG and HDL; analysis were determined by enzymatical methods using standardised commercial kits; LDL was calculated by Friedewald's formula, except in patients with levels of cholesterol over 400 mg/dL (LDL = TC - ([TG/5] + HDL).
MD was considered in this variable for the analyses including the chronic AUD group.
