Figures & data

Table 1 Demographic characteristics for the total and NeP sample

Figure 1 Comorbid conditions reported by at least 10% of the patients diagnosed with NeP (n=209).

Notes: 95% CI values are displayed. Patients could be diagnosed with multiple subtypes; hence, totals add up to >100%.
Abbreviations: CLBP-NeP, chronic lower back pain with a neuropathic component; CNP, central neuropathic pain; pDPN, painful diabetic peripheral neuropathy; GERD, gastroesophageal reflux disease; NeP, neuropathic pain; PSN, post-surgical neuropathic pain; PHN, postherpetic neuralgia; PTN, post-traumatic neuropathic pain.

Figure 2 NeP symptoms exhibited by physician-confirmed NeP patient during the examination.

Notes: 95% CI values are displayed. Totals reflect that patients could be diagnosed with multiple subtypes.
Abbreviations: CLBP-NeP, chronic lower back pain with a neuropathic component; CNP, central neuropathic pain; pDPN, painful diabetic peripheral neuropathy; NeP, neuropathic pain; PSN, post-surgical neuropathic pain; PHN, postherpetic neuralgia; PTN, post-traumatic neuropathic pain.

Figure 3 Clinical features of NeP and the clinical profile of patients for each NeP subtype: medication use.

Notes: 95% CI values are displayed. Totals reflect that patients could be diagnosed with multiple subtypes.
Abbreviations: CLBP-NeP, chronic lower back pain with a neuropathic component; CNP, central neuropathic pain; pDPN, painful diabetic peripheral neuropathy; NeP, neuropathic pain; PSN, post-surgical neuropathic pain; PHN, postherpetic neuralgia; PTN, post-traumatic neuropathic pain; SNRI, serotonin–norepinephrine reuptake inhibitors; SSRI, serotonin-specific reuptake inhibitor; TCA, tricyclic antidepressant.

Figure 4 Mean (95% CI) health status and economic burden of patients for each NeP subtype: EQ-5D.

Notes: Mean and 95% CI values are displayed. The Brazil population norms for the EQ-5D scales are overlaid on the figure (Health Utility 0.89; VAS 83.8).Citation28
