Change in the ALS Functional Rating Scale-revised (ALSFRSr) Score.

The ALSFRSr, a questionnaire-based scale assessing daily living function ranging from 48 (best score) to 0 (worst), was administered to the patient, or to a proxy if the patient could not communicate effectively. Decline was defined as ALSFRSr at baseline minus ALSFRSr at month 9. Thus a positive value indicates worsening. (NCT00243932)

Lower scores indicate greater impairment. Scores <24 are considered abnormal.~Activities of Daily Living scores:~The UPDRS part II is used to assess subject's degree in which they can perform their Activities of Daily Living. Part II of the UPDRS rates subjects on a 0-4 scale, with 0 being Normal and 4 being Severe Impairment, for each respective item. For each item, the reported score is divided by the maximum total score for that item and multiplied by 100 to give a 0-100 scale range. Higher scores indicate greater impairment." (NCT00382824)

Change in Total Motor Score From Baseline to Month 60

The motor section of the Unified Huntington's Disease Rating Scale (UHDRS) assesses motor features of Huntington disease with standardized ratings of oculomotor function, dysarthria, chorea, dystonia, gait, and postural stability. The total motor score is the sum of all the individual motor ratings, with higher scores (124) indicating more severe motor impairment than lower scores. The score ranges from 0 to 124. (NCT00608881)

Joint Rank (Combination of Time to Death (for Subjects Who Died) and Change in Total Functional Capacity Score (TFC) From Baseline to Month 60 (for Subjects Who Survived))

The primary outcome variable at the start of the trial was the change in TFC score from baseline to Month 60. The Data and Safety Monitoring Board recommended to the trial leadership that they reconsider how they accommodate missing data from subjects who die in their primary analysis of the change in TFC score. Based on these recommendations, the trial leadership changed the primary analysis to that of a joint rank approach. TFC consists of five ordinally scaled items assessing a person's capacity with: (1) occupation; (2) financial affairs; (3) domestic responsibilities; (4) activities of daily living; and (5) independent living. Total score ranges from zero (worst) to 13 (best). (NCT00608881)

We Measured the Change in Rate Constant of Creatine Kinase in Individuals With Bipolar Depression Treated With CoQ 10 as Compared With Age and Gender Matched Controls. These Rate Constants Were Calculated Using Magnetic Resonance Imaging (MRI).

The rate constant for creatine kinase is a measurement of the reaction rate ADP+PCr <---> ATP + Cr, which is catalyzed by the enzyme creatine kinase. The rate constant shows the direction and magnitude of the reaction at equilibrium. A higher rate constant indicates a higher rate constant of the CK enzyme, meaning, more efficient/rapid conversion of PCr to ATP through the creatine kinase enzymatic reaction in tissues with high and fluctuating energy demands such as brain and muscle tissue. As the value is a reaction rate, there are no associated units. (NCT00720369)

We Measured Response to Treatment of Depression (Using the Montgomery Asberg Depression Rating Scale)in Older Adults With Bipolar Disorder After an 8 Week Trial of CoQ10.

"The Montgomery Asberg Depression Rating Scale (MADRS) is a 10 question questionnaire which assesses symptom severity of depression. The score is on a 0-60 scale with higher numbers indicating more severe depressive symptoms. The score is represented as a number of points.~Clinical improvement following treatment with CoQ10 supplement was only tested in the Bipolar subject cohort, not in healthy controls, therefore outcome data only apply to the bipolar group."

Outcome is defined as change in total Unified Parkinson's Disease Rating Scale (UPDRS) between the baseline visit and month 16 or the time of sufficient disability to require dopaminergic therapy or study closure, whichever occurs first. The UPDRS score has three components, each consisting of questions answered on a 0-4 point scale. Part I assesses mentation, behavior and mood; Part II assesses activities of daily living in the week prior to the designated visit; and Part III assesses motor abilities at the time of the visit. A total of 31 items are included in Parts I, II and III. Each item will receive a score ranging from 0 to 4 where 0 represents the absence of impairment and 4 represents the highest degree of impairment. Total score ranges from 0-176. (NCT00740714)

Improvement in Left Ventricular Filling Abnormality

Doppler-derived transmitral blood flow and pulmonary venous blood flow data were used for grading of the severity of diastolic filling abnormality in patients before and after the intervention. Diastolic filling abnormality was categorized as: 1- normal 2- abnormal relaxation 3- pseudonormal 4- restricted pattern based on echo data. The proportion of patients who showed improvement in the diastolic function grading was compared between the study groups. (NCT02115581)
