About key messages

Key messages provide a descriptive index to studies we have found that test this intervention.

Studies are not directly comparable or of equal value. When making decisions based on this evidence, you should consider factors such as study size, study design, reported metrics and relevance of the study to your situation, rather than simply counting the number of studies that support a particular interpretation.

Supporting evidence from individual studies

  1. A before-and-after study in 2005–2006 of gullypots along roads in South Wales, UK (Muir 2012) found that moving the gullypot 10 cm away from the kerb resulted in 80% fewer great crested newts Triturus cristatus falling into the gullypots. Only 65 newts were found in the drains compared to 318 before gullypots were moved. Gullypots were moved in 2005.
