2️⃣Performance bias➡️can mean: differences in care to participants (other than what is being evaluated) or changing behaviour/responses due to knowing which group they are in. This can cause differences that may not be from treatment/intervention. This bias is reduced by blinding

1️⃣ Selection bias ➡️ occurs when randomisation is not achieved appropriately & can mean there is personal interference in the selection of trial participants/groups. The sample may not be representative of the study population to be analysed. This can cause misleading results❌
