Randomisation and masking
INTRACEREBRAL HAEMORRHAGE
Eligible hospital sites were randomly assigned into three sequences (with four periods) by use of a computer-generated list by the trial statistician (QL) using permuted blocks, stratified by country and the projected number of patients to be recruited per site during the study period (<80, 80–160, and >160 patients). In period 1, all sites kept to their usual care and monitoring procedures for patients with intracerebral haemorrhage. Sites assigned to sequence 1 commenced the care bundle in period 2, those in sequence 2 received the intervention at period 3, and those in sequence 3 received the intervention at period 4, as outlined in the For logistical reasons and according to available funding, sites were activated in batches beginning in China in 2017, and subsequently in the other countries in 2019 (
