Note. Table demonstrate effect sizes when including censored data at the earliest possible unobserved symptom onset. Values represent Cohen’s d for paired samples t-tests. Effect sizes are bolded to demonstrate statistical significance at p < .05. Effect sizes should be interpreted from right (column) to left (row). For instance, the first column indicates that body image followed overvaluation (due to a positive effect size), whereas it preceded all other symptoms (indicated by a negative effect size). Negative effect size signs indicate symptoms that preceded the reference symptom; positive effect size signs indicate symptoms that followed the reference symptom
