Change in Low Density Lipoprotein Cholesterol (LDL-C) after 270 days of treatment in adults on established lipid lowering medication or who have been recommended lipid lowering therapy by their health care provider but are unable to tolerate treatment, regardless of treatment discontinuation for any reason and regardless of unforeseen change in the concomitant lipid lowering therapy.

Multiple imputation is used to impute missing data using a washout model.

Full analysis set. The Full Analysis Set (FAS) comprised of all randomized participants except for those mis-randomized participants who did not receive study drug. Only participants with LDL-C values at both, baseline and Day 270, were included in the analysis.

To identify the need to support the implementation of inclisiran in the real world, a framework was drawn known as the Consolidated Framework for Implementation Research (CFIR). Patients who received inclisiran were interviewed to understand their experience with the program and to obtain a comprehensive understanding, with or without behavioural support. These patients were interviewed on various aspects of their experience related to their high cholesterol management, trial participation, inclisiran injections, attending appointments, and if applicable their experience with the behavioural support programme.

These interviews were not set up in a way that allow numerical analysis. The process evaluation was conducted by Manchester University.

All patients randomized to inclisiran

The Client Satisfaction Questionnaire (CSQ)-8 is the standard self-administered CSQ scale containing 8 items that comprise the measurement of satisfaction with services and measurement of improvement of capacity to cope and change adaptively. Items include questions enquiring about respondents' opinions and conclusions about services they have received or are currently receiving. Response options differ from item to item, but all are based on a four-point scale. For the CSQ-8 version, scores range from 8 to 32, with higher values indicating higher satisfaction.

This secondary outcome only analysed data of the two Inclisiran arms, by considering the Inclisiran only arm as the control group. The standard error for Least Square Mean could change because dropping a treatment arm affects the estimation of treatment effects and the variability of data.

The Patient Activation Measure (PAM) questionnaire is a survey that assesses a person's underlying knowledge, skills and confidence integral to managing his or her own health and healthcare.

This study used the 13-point PAM questionnaire, which consists of 13 statements relating to patients beliefs about health care, confidence in their management of health related tasks, and self-assessed knowledge of their condition. For each statement patients are required to say how much they either agree or disagree on a response scale of 1-5, where 1 represents "strongly disagree", 4 represents "strongly agree" and 5 indicates that the statement is "not applicable" to them. A standardised spreadsheet in excel is used to score the PAM. Responses are used to generate a continuous score from 0 to 100 where higher scores indicate that the patient is more activated.

This outcome only analysed data of the two inclisiran arms, by considering the Inclisiran only arm as the control group. In an ANCOVA model, the Least Squares Means and corresponding Standard Error could change because the removal of a treatment group affects the estimation of the treatment effects and the adjustment for the covariate(s).

The continuous PAM scores are then categorised into 4 levels: Level 1 - disengaged and overwhelmed; Level 2 - become aware but still struggling; Level 3 - taking action; Level 4 - maintaining behaviors and pushing further.
