About this study

Official title: An Evidence-Based Novel Subtypes of Polycystic Ovary Syndrome and Their Association With Outcomes: a Large Cohort Study

To classify subtypes of Polycystic Ovary Syndrome (PCOS) using machine-learning algorithms, and compare the reproductive and metabolic characteristics and IVF outcomes across these identified subtypes.

Read the detailed description

In this study, we've developed a machine-learning model to classify PCOS patients into four subtypes based on nine clinical characteristics.

The goal of this observational study is to:

  • Learn about different PCOS subtypes using our classification model.
  • Compare the reproductive and metabolic features of these subtypes.
  • Assess the outcomes of IVF among different PCOS subtypes.
  • Prospective 6.5-year follow-up data will be collected.

Participants will:

  • Undergo a telephone interview to gather details on:
  1. Current physical stats like height and weight.
  2. Reproductive history, including pregnancies and childbirths in recent years.
  3. Details about any IVF treatments.
  4. Current status of conditions such as PCOS, Type 2 Diabetes, hypertension, and dyslipidemia.
  • Be invited for a physical examination that includes:
  1. Measurements such as height, weight, blood pressure, and body circumferences.
  2. Laboratory tests for endocrine and metabolic conditions.
  3. Ultrasound scans of the ovaries and liver.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Long-term follow-upOther

    Participants diagnosed with PCOS were not subjected to any specific intervention post-diagnosis. Instead, they were followed up after 6.5 years to assess various outcomes related to PCOS and associated conditions.

Study groups in NCT06124391
Study groupRoleWhat they receive
HA-PCOSPatients were classified into each PCOS subtype based on our machine-learning classification model. The feature of the HA-PCOS group is hyperandrogenism.
Receives: Other: Long-term follow-up
OB-PCOSPatients were classified into each PCOS subtype based on our machine-learning classification model. The feature of the OB-PCOS group is overweight/obesity.
Receives: Other: Long-term follow-up
SHBG-PCOSPatients were classified into each PCOS subtype based on our machine-learning classification model. The feature of the SHBG-PCOS group is the high level of serum SHBG.
Receives: Other: Long-term follow-up
LH-PCOSPatients were classified into each PCOS subtype based on our machine-learning classification model. The feature of the LH-PCOS group is the high level of LH and AMH.
Receives: Other: Long-term follow-up

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Persistence of PCOS Diagnosis

    Determining if patients still meet the Rotterdam criteria for a PCOS diagnosis at the follow-up. The hyperandrogenic, ovulatory, and polycystic ovarian conditions at the follow-up time will be assessed.

    Measured: At the 6.5-year follow-up visit.

  2. Changes in PCOS Subtype

    Tracking if patients have transitioned between different PCOS subtypes at the follow-up.

    Measured: At the 6.5-year follow-up visit.

  3. Body Mass Index

    Patients' weight (in kilograms) and height (in meters) will be collected and combined to report BMI in kg/m^2

    Measured: At the 6.5-year follow-up visit.

  4. Non-Alcoholic Fatty Liver Disease (NAFLD)

    NAFLD will be assessed using abdominal ultrasound.

    Measured: At the 6.5-year follow-up visit.

  5. Hypertension

    Blood pressure will be assessed, and we will determine if a patient has hypertension, defined as systolic blood pressure (SBP) ≥ 140 mmHg and/or diastolic blood pressure (DBP) ≥ 90 mmHg.

    Measured: At the 6.5-year follow-up visit.

  6. Type 2 Diabetes Mellitus (T2DM)

    Fasting glucose will be assessed, and we will determine if a patient has T2DM, defined as fasting glucose ≥ 7.0 mmol/l.

    Measured: At the 6.5-year follow-up visit.

  7. Dyslipidemia

    Defined as the presence of any of the following abnormalities:

    • Total cholesterol ≥ 5.2 mmol/l
    • Triglycerides (TG) ≥ 1.7 mmol/l
    • High-density lipoprotein (HDL) < 1.0 mmol/l
    • Low-density lipoprotein (LDL) ≥ 3.35 mmol/l

    Measured: At the 6.5-year follow-up visit.

  8. Total live birth rate

    Live birth is defined as the delivery of any neonate with signs of life at ≥ 28 weeks of gestation.

    Measured: From the diagnosis of PCOS (at the time of enrollment) until a follow-up period of 6.5 years.

  9. Clinical pregnancy rate

    Clinical pregnancy is defined as the ultrasound confirmation of at least one intrauterine gestational sac.

    Measured: From the diagnosis of PCOS (at the time of enrollment) until a follow-up period of 6.5 years.

  10. Pregnancy loss rate

    Pregnancy loss is defined as pregnancies that eventuate in a spontaneous abortion or therapeutic abortion that occurred throughout pregnancy.

    Measured: From the diagnosis of PCOS (at the time of enrollment) until a follow-up period of 6.5 years.

  11. Maternal and neonatal complications

    Any maternal and neonatal complications, including gestational diabetes, preeclampsia, etc., will be collected.

    Measured: From the diagnosis of PCOS (at the time of enrollment) until a follow-up period of 6.5 years.

What does the primary outcome measure?

Persistence of PCOS Diagnosis (time frame: At the 6.5-year follow-up visit.). The study lists 11 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
