Comorbidity	The presence of one or more additional health conditions co-occurring with a primary condition.
Confidence interval (in statistics)	A statistical range that estimates the uncertainty around a measurement. When reported as 95% CI, it represents the range of values within which the true population parameter is expected to lie 95% of the time, if the same study were repeated under the same conditions.
Consensus-based recommendation	A recommendation based on available evidence, clinical expertise, and consumer/expert opinion, and formulated using a structured Delphi consensus process, after a systematic review of the evidence found insufficient quality evidence on which to base a recommendation.

Control group	The group that does not receive the treatment or intervention being tested (typically used as a comparison in a study).
Delphi	A research method that typically involves multiple rounds of surveys or questionnaires to gather expert opinions and achieve consensus on a specific topic. In the current guideline, consensus is defined as at least 75% agreement on each statement.
Deprescribing	Deprescribing is a person-centred process of tapering, stopping, discontinuing, or withdrawing one or more medicines that are considered inappropriate or no longer beneficial to improve outcomes.
Evidence-based recommendation	An evidence-based recommendation, according to the GRADE approach, is a clinical or policy recommendation that is concise, clear, actionable, and informed by a systematic and transparent assessment of the available research evidence, taking into account the balance between the benefits and risks of, individual's values and preferences, resource use, costs, acceptability, the feasibility of implementation, and health equity indicators.
Exacerbation	A worsening or flare-up of a disease or condition.
Frail	A state of increased vulnerability due to reduced physiological reserve across multiple physiological systems.
General practitioner	A General Practitioner (GP) is a medical doctor with a core responsibility to provide comprehensive, continuous care across a wide range of health conditions. Most GPs work in primary care settings, where they play a central role in coordinating healthcare, referring patients to specialists when necessary, and delivering ongoing management of chronic conditions, preventive care, and health education.
Geriatric 5Ms	A framework that includes: Mind, Mobility, Medicines, Multicomplexity, and what Matters most.
Good practice statement	A statement formulated using a structured Delphi consensus process, on a subject outside the scope of the systematic review, that is intended to support the guideline recommendations or implementation in practice.
GRADE (Grading of Recommendations, Assessment, Development and Evaluation) framework	A systematic framework commonly used in guideline developments to assess the certainty of evidence and determine the strength of recommendations in healthcare guidelines.
Harms (of a test or treatment)	Negative and undesirable outcomes or effects expected or resulting from an intervention (including a test or treatment).
Hazard ratio	A ratio of the rate at which one group experiences an outcome to the rate at which another group experiences an outcome of interest over time.
Healthcare professional	A person trained to deliver healthcare services.
Hyperbolic tapering	Hyperbolic tapering is a dose reduction strategy for certain medicines in which medicine doses are decreased in progressively smaller increments to achieve a linear reduction of receptor occupancy to minimise withdrawal symptoms.
Informed consent (in healthcare)	The Australian Commission on Safety and Quality in Health Care defines informed consent as a person’s voluntary decision to agree to a healthcare treatment, procedure or other intervention that is made: 1) following the provision of accurate and relevant information about the healthcare intervention and alternative options available; and 2) with adequate knowledge and understanding of the benefits and material risks of the proposed intervention relevant to the person who would be having the treatment, procedure or other intervention.
Intermittent	Occurring at irregular intervals; not continuous.
Life expectancy	An estimate of the average number of years a person can expect to live.
Mean difference	A measure that quantifies the difference between the mean (i.e. average) values of two groups.
Medication adherence	The extent to which consumers take prescribed medicine in line with the agreed plan with the prescriber
Medication compliance	The extent to which consumers take their prescribed medicines exactly as instructed by the prescriber.
Monitoring	The process of observing and checking the progress or quality of a patient’s condition or therapy.
MRONJ	Medication-related osteonecrosis of the jaw, a rare but serious side effect of certain medicines.
Multimodal	The use of more than one method or approach in treatment or care.
Multimorbidity	The presence of two or more chronic health conditions.
Odds ratio	A ratio of the odds of the event occurring in one group versus another group.
Off-label	The use of a medicine for a condition or population not specifically approved by regulatory authorities.

Over-prescribing	The prescribing of medicines that are inappropriate, no longer necessary, or where the potential harms outweigh the benefits.
Palliative care	Palliative care is a specialised medical care for anyone living with a life-limiting illness, such as cancer or advanced stages of dementia, as well as their carers or family members.

Pro re nata	A Latin term meaning "as needed"; typically refers to medicines not taken on a fixed schedule.
Randomised controlled trial	A prospective study design that evaluates the effectiveness of an intervention or treatment by randomly assigning participants to different groups. This approach allows for the examination of cause-and-effect relationships between the intervention and specific outcomes.
Relative risk	A measure that compares the probability of an event occurring in one group versus the probability of that event occurring in another group, often used to assess the effect of an exposure or treatment.
