Eligibility criteria

Question element

Screening stage

Uses an aquatic animal

 Animal that have at least one phase of their life as obligate aquatic (e.g. fish, amphibian, aquatic mammal, aquatic invertebrate)

Population (P)


Uses a wild type animal

 An animal that is not genetically modified

Population (P)

Full text

Uses at least one pharmaceutical compound

 A decision tree will be used to assist screeners in deciding whether a compound qualifies as a pharmaceutical compound (Additional file 1: Figure S1)

Exposure (E)


Has a control group

 A non-exposed group to which the exposed group is compared and is therefore not a review, meta-analysis, conference proceeding etc

Comparator (C)


Measures behaviour

 An organism’s kinematic response, or lack of kinematic response (e.g. freezing, resting), to an internal or external stimulus (e.g. foraging in response to hunger [internal] or food [external] stimuli [40])

Outcome (O)


Is in a language in which our review team is proficient

 English, Swedish, Norwegian, Czech, Slovak, Japanese, Polish, Russian
