Concepts

1. PCC Transitions

   "Of the 609 participants with PCC in 2021, 354 (58.1%) were successfully followed up in 2024.\n\nFigure 2 shows the transitions between PCC and recovery status over time. Most participants (274 [77.4%

2. PCFS Changes

   "Figure 3 illustrates the corresponding changes in PCFS grades among participants with available follow-up data (n = 354). Between 2021 and 2024, 105 (29.7%) showed improvement, 193 (54.5%) remained s

3. Population Stability

   "Despite these bidirectional transitions, the overall distribution of PCFS grades at the population level remained largely unchanged, suggesting that improvements and worsening balanced each other ove
