WOMAC: self-administered, disease-specific questionnaire which assesses clinically important, participant-relevant symptoms for pain, stiffness and physical function in participants with osteoarthritis. The WOMAC pain subscale is a 5-item questionnaire used to assess the amount of pain experienced due to osteoarthritis of index joint (knee or hip) during past 48 hours.

WPAI is 6-question participant rated questionnaire to determine the impact of osteoarthritis on absenteeism, presenteeism, work productivity, and daily activity impairment for a period of 7 days prior to a visit.

EQ-5D-5L is a standardized participant completed questionnaire that measures health-related quality of life and translates that score into an index value or utility score. EQ-5D-5L consists of two components: a health state profile and an optional visual analogue scale (VAS). EQ-5D health state profile is comprised of 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: 1=no problems, 2=slight problems, 3=moderate problems, 4=severe problems, and 5=extreme problems. The health utility score for a patient with no problems in all 5 items is 1 for all countries (except for Zimbabwe where it is 0.9), and is reduced where a patient reports greater levels of problems across the five dimensions.

Measurement of BP included sitting systolic (SBP) and diastolic BP (DBP).

A 12-lead ECG was recorded after participants had rested for at least 5 minutes in the supine position in a quiet environment. All standard intervals (PR, QRS, QT, QTcF, QTcB, QTcF, RR intervals) were collected.

Incidence of participants with any of the joint safety adjudication outcomes of primary osteonecrosis, rapidly progressive osteoarthritis (OA) (type 1 and type 2), subchondral insufficiency fracture (or SPONK), or pathological fracture.

The safety population was defined as all participants treated with Tanezumab or placebo subcutaneously. Here, 'Overall number of participants analyzed' signifies participants analyzed by adjudication committee.

Percentage of participants who underwent total knee, hip or shoulder joint replacement surgery.

NIS is a standardized instrument used to evaluate participant for signs of peripheral neuropathy. NIS is the sum of scores of 37 items, from both the left and right side, where 24 items scored from 0 (normal) to 4 (paralysis), higher score indicated higher abnormality/impairment and 13 items scored from 0 (normal), 1 (decreased) and 2 (absent), higher score indicated higher impairment. NIS possible overall score ranged from 0 (no impairment) to 244 (maximum impairment), higher scores indicated increased impairment.

Orthostatic hypotension was defined as postural change (supine to standing) that met the following criteria: For systolic BP <=150 mmHg (mean supine): Reduction in systolic BP>=20 mmHg or reduction in diastolic BP>=10 mmHg at the 1 and/or 3 minute standing BP measurements. For systolic BP >150 mmHg (mean supine): Reduction in systolic BP>=30 mmHg or reduction in diastolic BP>=15 mmHg at the 1 and/or 3 minute standing BP measurements. If the 1 minute or 3 minute standing BP in a sequence met the orthostatic hypotension criteria, then that sequence was considered positive. If 2 of 2 or 2 of 3 sequences were positive, then orthostatic hypotension was considered confirmed.

The safety population was defined as all participants treated with Tanezumab or placebo subcutaneously. Here, 'Overall number of participants analyzed' signifies participants analyzed for this outcome measure.

The SAS is a 12 item (11 for females) questionnaire, from which the total number of symptoms (0-12 for males and 0-11 for females) is calculated. Each positive symptom is rated from 1 (not at all) to 5 (a lot). The total impact score was the sum of all symptom rating scores, with 0 assigned where the participant did not have the particular symptom. The range for the total impact score is 0-60 for males and 0-55 for females, higher scores indicating higher impact.

Human serum ADA samples were analyzed for the presence or absence of anti-tanezumab antibodies by using a semi quantitative enzyme linked immunosorbent assay (ELISA). Participants listed as having anti-tanezumab antibodies had ADA titer level >=3.32. Less than 3.32 was considered below the limit of quantitation.
