a, Pressure-dependent 1/T1T and Tc. 1/T1T under each pressure is calculated by the weighted average method that sums up 1/T1T measured on each peak with its spectrum weight. The spectrum weight is determined by the normalized integration area of 1/T1T as shown in Extended Data Fig. 9. All 1/T1T data were collected at 10 K above the maximum value of Tc. To avoid effect from the phase transition, only 1/T1T belonging to a pure phase is plotted here. All data points are collected in sample B. b, Plot of 1/T1T vs Tc under the same pressure in a. All data points can be separated into two groups. It is obvious that the data in different CDW phases (triple-Q CDW and stripe-like CDW) exhibit a similar linear behaviour, supporting a strong correlation between Tc and 1/T1T in the CDW phase. In the kagome phase, the data seem to follow a similar linear behaviour with the same slope but the disappearance of the CDW order leads to a constant shift in 1/T1T
