@TWKsicem @luckytran @JoannaConn3lly Yes, they are.
Based on age demographics, Japan had a baseline (original variant, pre-vax) IFR of about 2% and the US more like 1%. Obesity increases risk by around 2x (maybe less for "merely" obese but not severely), and US has 30% more than Japan. Age 3x more significant.
@TWKsicem@luckytran@JoannaConn3lly是的，他们是。
根据年龄统计数据，日本的基线（原始变量，vax前）IFR约为2%，美国约为1%。肥胖会增加大约2倍的风险（对于“单纯”肥胖的人来说可能更少，但并不严重），美国比日本多30%。年龄是显著年龄的3倍。
