TABLE 3.
Determinants of belonging to each trajectory based on mean total number of long COVID symptoms.
| Long COVID symptom trajectory | ||||||

| COVID‐19 wave | ||||||
| First wave | Ref. | Ref. | Ref. | |||
| Subsequent waves | 0.78 (0.37–1.65) | 0.520 | 0.98 (0.42–2.29) | 0.964 | 5.26 (1.03–26.9) | 0.046 |
Note: BMI was defined in kg/m2 as: <25, underweight or normal weight; 25–29, overweight; ≥30, obese. COVID‐19 wave defined as: first wave (up to 1 June 2020) and subsequent waves (on or after 1 June 2020). Long COVID symptoms were defined as those developing within 1 month of overall illness onset, in order to exclude sporadic symptoms that were less likely to be attributed to the consequences of COVID‐19.
Abbreviations: aOR, adjusted odds ratio; CI, confidence interval.
