Outcomes following lymphaticovenous anastomosis (LVA) for 100 cases of lymphedema: results over 24-months follow-up

“…Analysis: Paired Samples T -Test. * Statistically significant difference: A decrease of 10, 15, 12, 23, 15, and 14 in total score, physical function, mental function, household activities, mobility activities, and life and social activities were considered a statistically significant difference ( p < 0.05) [ 29 ] …”

“…When concerning the final Lymph-ICF measurement at the last outpatient appointment for each patient (n = 100), a lower postoperative total score in each domain of the Lymph-ICF was observed. However, only in domain 'physical function' and 'mental function' a decrease of more than 10 was observed, representing a statistically significant decrease (p < 0.05) [29]. See Fig.…”

“…Disease-specific QoL was measured by the Dutch Lymphedema Functioning, Disability, and Health questionnaire (Lymph-ICF) [29]. This is a validated questionnaire to evaluate limb specific symptoms in lymphedema patients using a Visual Analogue Score (VAS), with the advantage of a wide score range and high sensitivity [30,31].…”

“…A decrease in VAS of more than 10 in the total score was considered to be statistically significant (p < 0.05). [29].…”

Advanced translation and cultural adaption of the LYMPH-Q Upper Extremity Module from English to Danish

“…Second, the method used to calculate the score in the LYMPH-Q Upper Extremity Module is developed according to Rasch Measurement Theory (RMT) where the revised Lymph-ICF was evaluated looking at intraclass correlation coefficients for test-retest reliability and Cronbach's alpha coefficients for internal consistency [25]. Hobart and Cano conclude that RMT has several advantages when measuring PRO in health care [26].…”
