The Times ÖйúAƬ World University Rankings 2019 clinical, pre-clinical and health subject ranking includes a range of narrower subject areas.

The subjects used to create this ranking are:

• Medicine and dentistry
• Other health

Different weights and measures

The subject tables employ the same range of 13 performance indicators used in the overall World University Rankings 2019, brought together with scores provided under five categories.

However, the overall methodology is carefully recalibrated for each subject, with the weightings changed to suit the individual fields.

The weightings for the clinical, pre-clinical and health ranking are:

ÖйúAƬ

Teaching: the learning environment
27.5?per cent

Research: volume, income and reputation
27.5?per cent

Citations: research influence
35?per cent

International outlook: staff, students and research
7.5?per cent

ÖйúAƬ

Industry income: innovation
2.5?per cent

Criteria

There are two criteria to be included in the subject rankings: a publication threshold by discipline and an academic staff* threshold by discipline.

No institution can be included in the overall World University Rankings unless it has published at least 1,000 research papers over the five years that we examine.

For the 11 subject tables, the publication thresholds are set differently. For clinical, pre-clinical and health, the threshold drops to 500 papers published in this discipline over the past five years.

There is also an academic staff eligibility criterion. Up through?the 2018?subject rankings, an institution had to have at least 5?per cent of its academic staff working in the clinical, pre-clinical and health discipline?to be included in the subject table.

ÖйúAƬ

For the 2019 subject rankings, we have made a small adjustment in the staff eligibility criterion. An institution must have at least a minimum proportion of its staff or at least a minimum specific number of its staff in this discipline to be included in the subject ranking.

For clinical, pre-clinical and health, an institution?must have at least 5?per cent of its academic staff or at least 50 academic staff in the discipline.

*Academic staff is defined as the full-time equivalent number of staff employed in an academic post, eg, lecturer, reader, professor.
