Why
  1. The study's title name Ischemic Stroke, a narrower term within Stroke.
Confidence
High: the new condition is named in the study's own title. Of 46 hand-checked studies reclassified this way, 72% were exactly right and 89% in the right disease family; the registry's first term was right for 4% (measured 2026-10-21). How we classify →

Study summary

This observational study aims to research whether there is a relationship between omentin and ischemic stroke on the aspects of incidence, severity, and recovery etc.

Read the detailed description

To study the possible relationship between omentin and ischemic stroke, we intend to recruit the newly found acute ischemic stroke patients and patients without any stroke history and analysis the difference of plasma omentin level and the ITLN, which is the gene symbol of omentin.

In context

Ischemic Stroke Reclassified

2,612 studies on the registry are indexed under Ischemic Stroke; 971 are open to participants now.

This study's planned enrollment of 2,000 is above the median of 300 across 771 observational studies indexed under Ischemic Stroke.

Lead sponsor

Xi'an No.3 Hospital is the lead sponsor of 7 studies on the registry; 7 are open to participants now.

Compared within Ischemic Stroke, this study's primary condition as ClinicalTrials.gg classifies it; the registry's first condition term is Stroke. The counts are of registry records indexed under each term, refreshed daily. How we classify →

What researchers measure

Primary outcomes

  1. the odds ratio of omentin plasma concentration between cases and controls

    The circulation level of omentin will be assessed in cases and controls. Then the odds ratio will be statically analysed to detect whether omentin is asociated with ischemic stroke on protein level.

    Time frame: up to 3 years

  2. the frequency difference of single nucleotide polymorphism(SNP) of omentin in the enrolled subjects

    The SNP will be analysed in the recruited subjects. And the the frequency difference will be calculated to explore if any SNP is related to ischemic stroke.

    Time frame: up to 3 years

Secondary outcomes

  1. the NIHSS assessed for functional outcome of stroke

    NIHSS wil be used to assess neurological status at baseline or the point of stroke, the point of out-patient, 3 month, 6 month, 1 year, 2 year and the 3 year.

    Time frame: up to 3 years

  2. the modified Rankin Scale assessed for functional disability

    Th functional disability will be assessed using the modified Rankin Scale at the time of baseline, out-patient, 3rd month, 6th month, 1st year, 2nd year and the 3rd year after enrollment.

    Time frame: up to 3 years

  3. the Barthel index assessed for functional independence in activities

    The Barthel index at the point of baseline, out-patient, 3rd month, 6th month, 1st year, 2nd year and the 3rd year after enrollment will be assessed for the functional independence in activities.

    Time frame: up to 3 years

  4. the number of all cause death

    The number of all cause of death will be recorded in both groups.

    Time frame: up to 3 years

  5. the number of re-stroke in case group

    Recurrent of stroke will be monitored through out in case group.

    Time frame: up to 3 years

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Jan 2017 (actual). Primary completion is estimated for Dec 2025, 107 months after the start.

Of 394 non-industry observational studies under Ischemic Stroke, half reached primary completion within 56 months of starting (the median), counting those still running; a quarter within 25 and three quarters within 140. This study's planned 107 months is above that.

Counting every sponsor, half of 436 studies reached it within 53 months; a quarter within 24 and three quarters within 127.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 24, 2017, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
