Figure 3.
Extended time between first symptoms and diagnosis (≥2 years) model displayed in a forest plot. The odds ratios (ORs) and 95% confidence intervals (CIs) of the individual factors are shown on a log2 scale and the point estimates are stated at the right side of the plot. Values higher than 1 indicate an association with extended time, below 1 with shorter time. The reference levels of the factors are (from top to bottom, variable in brackets): type of MS: relapsing-onset MS (primary progressive MS), sex: female (male), diagnosis period: 1996–2000 (diagnosis period: 2001–2005, 2006–2010, 2011–2015, 2016–2017), diagnosis setting: neurologist (hospital) (neurologist (private practice), general practitioner) and absence of the stated first symptoms (gait problems first symptom, paresthesia first symptom). diag.: diagnosis; pract.: practice; FS: first symptoms. The results are displayed on a log2 scale to give the positive and negative factors the same weight.
