In this secondary analysis of the BISTRO trial we wished to establish whether centre-level practices with the potential to affect fluid status were stable over the course of the trial and explore if they had any residual associations with participant's fluid status.</p><p><strong>Methods: </strong>Two surveys (S) of fluid management practices were conducted in 32 participating centres during the trial, (S1: 2017-18 and S2: 2021-22). Domains interrogated included: dialysate sodium concentration, (D-[Na<sup>+</sup>]), fluid and salt intake, residual kidney function, use of diuretics, incremental start, approaches to fluid assessment, management and dialysate temperature, (D-<sup>o</sup>C). Associations of these practices with the closeness of the participant's post-dialysis target weight to their normally hydrated weight, pre- and post-dialysis systolic (SBP) and diastolic blood pressure, (DBP), were analysed using intra-class correlations and multilevel modelling with adjustment for visit, age, sex and comorbidity burden.</p><p><strong>Results: </strong>Variations in centre practices were reported but did not change during the trial, apart from some relaxation in salt and fluid restriction in S2. For our measures of fluid status, measured 2501 times in 439 non-anuric incident haemodialysis patients, centre-level intraclass correlations were extremely low, whereas patient-level correlations ranged between 0.12 and 0.47, strongest for pre- and post-dialysis-SBP, less so for post-dialysis-DBP. Multi-level analysis found no associations between D-[Na<sup>+</sup>], or assessment methods of fluid status.

Considering the intolerance of chemotherapy and high tumor mutation burden, we administered the anti-PD-1 agent tislelizumab (200 mg every three weeks).
