Topics.
Three ways into the same corpus: by biological system, by section, or by type of evidence.
By biological system
- InflammationInflammation: mechanisms, resolution and evidence in horse and human
- MicrobiomeMicrobiome, fermentation and metabolites: horse and human compared
- Connective tissueConnective tissue, tendons and remodelling: why mature tendon tissue is barely renewed
- AirwaysEquine asthma and air quality: what links dust, hay and the lung
By section

- Evidence Lab2 checked syntheses
- Nutrition Science1 checked synthesis
- Microbiome1 checked synthesis
- Equine Health2 checked syntheses
- Comparative Health2 checked syntheses
By type of evidence
- Meta-analysisPools several studies statistically. It can estimate an effect more precisely, but it inherits the weaknesses of the studies it includes.38
- Systematic reviewSearches the literature by a method fixed in advance. It shows reliably what exists, and just as reliably what is missing.23
- Randomised trialAllocates by chance. It is the only design that can separate a cause from a mere co-occurrence.25
- Controlled trialCompares against a control group without randomisation. The comparison stays open to systematic differences between groups.20
- Cohort studyFollows a group over time. It shows associations, never a cause: the decisive difference often sits outside what was measured.18
- Case-control studyCompares affected and unaffected individuals retrospectively. Useful for rare events, sensitive to recall error.8
- Cross-sectional studyCaptures a state at one point in time. It tells you how common something is, not what came first.17
- Case seriesDescribes a run of cases with no comparison group. It generates hypotheses and tests none.2
- Professional guidelineA recommendation from a professional body or authority. It blends evidence and expert judgement, and the two can be told apart.3
- Laboratory studyA controlled experiment outside clinical reality. It explains a mechanism; it does not establish an effect in a living body.13
- OtherWork that fits none of the designs above, including methodological contributions and overviews.28
The evidence letter
Once a month: new syntheses, checked studies, and what has changed in the state of the evidence.
