Trial Outcomes & Findings for Metformin, Vitamin D, and Depression in Polycystic Ovary Syndrome (PCOS) Trial (NCT NCT03380091)

NCT ID: NCT03380091

Last Updated: 2021-02-09

Results Overview

BDI-II is a validated self-reported instrument of 21 questions which are each scored 0-3. Total scores range from 0-63, with higher score totals indicating more severe depression symptoms. {0-9: indicates minimal depression; 0-18: indicates mild depression; 19-29: indicates moderate depression; 30-63: indicates severe depression}. Change = Week 12 total score - Baseline week score

PRIMARY outcome

Timeframe: Baseline & 12 weeks

Population: In both the Vitamin D and the Metformin arms, only 1 participant in each arm was analyzed for Change in Depression from Baseline as only 1 participant in each arm participated through to week 12. A Change could not be calculated for the other 3 participants as no week 12 scores were available.

BDI-II is a validated self-reported instrument of 21 questions which are each scored 0-3. Total scores range from 0-63, with higher score totals indicating more severe depression symptoms. {0-9: indicates minimal depression; 0-18: indicates mild depression; 19-29: indicates moderate depression; 30-63: indicates severe depression}. Change = Week 12 total score - Baseline week score

SECONDARY outcome

Timeframe: Baseline week & week 12

Population: In both the Vitamin D and the Metformin arms, only 1 participant in each arm was analyzed for Change in Insulin Resistance from Baseline as only 1 participant in each arm participated through to week 12. A Change could not be calculated for the other 3 participants as no week 12 serum insulin and glucose test results were available.

Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) will be used to calculate Insulin Resistance based on fasting glucose (mg/dL) and fasting insulin (μIU/mL) blood serum assays tested at Quest Diagnostics. HOMA-IR = Fasting Insulin (uIU/mL) x Fasting Glucose (mg/dL). Healthy range is between 0.5-1.4. Values below 1.0 indicate insulin sensitivity and are optimal. Values greater than 1.9 indicate clinically significant insulin resistance.

SECONDARY outcome

Timeframe: Baseline week & Week 12

Population: In both the Vitamin D and the Metformin arms, only 1 participant in each arm was analyzed for a Change in Anxiety scores from Baseline as only 1 participant in each arm participated through to week 12. A Change could not be calculated for the other 3 participants as no week 12 scores were available.

STAI-S is a validated self-reported instrument of 20 questions. Range of scores for the State Anxiety (STAI-S) subtest is 20-80, the higher score indicating greater anxiety. A threshold point score of 39-40 has been suggested by recent literature to detect clinically significant symptoms. Change = Week 12 total score - Baseline week score

SECONDARY outcome

Timeframe: Baseline week & week 12

Population: In both the Vitamin D and the Metformin arms, only 1 participant in each arm was analyzed for Change in Vitamin D serum levels from Baseline as only 1 participant in each arm participated through to week 12. A Change could not be calculated for the other 3 participants as no week 12 serum Vitamin D test results were available.

Vitamin D, 25-hydroxy blood serum assays will be tested at Quest Diagnostics. Changes in values from baseline week to week 12 will be calculated. Reference ranges: optimal 30-100 ng/mL Insufficient 20-29 ng/mL deficient \<20ng/mL
