Heatmaps of self-reported symptom clusters and forest plots showing odds of chest pain and palpitations associated with individual symptoms. Legend: A Heatmaps demonstrating hierarchical clustering on self-reported symptoms. WT group (1st March 2020-25th December 2020) is shown on the left and VOC group (26th December 2020- 1st March 2022) on the right. VOC group included 124 individuals with acute infection in the alpha variant dominant period and 25 infected in the delta dominant period. In both groups the top cluster is a musculoskeletal cluster (n = 69 (26%) in WT and n = 23 (15%) in VOC), the middle is a cardiorespiratory cluster (n = 134 (50%) in WT and n = 30 (20%) in VOC) and the bottom is a less symptomatic cluster (n = 65 (24%) in WT and n = 94 (63%) in VOC).
