“…Additional file 4 presents individual study results, including effect estimates and confounders that were included in calculations. Eighty-two percent of studies demonstrated a statistically significant association between the presence of multisite pain and falls when adjusting for confounding factors [5–7, 9, 10, 12, 13, 15, 16, 18–23, 26, 28]; 18% of studies found no statistically significant relationship between multisite pain and falls after adjusting for confounders [14, 17, 24, 27]. Studies that classified multisite pain by number of pain sites or included a measure of widespreadness found a linear correlation between the number of pain sites and an increasing risk of falls [5, 6, 22, 23, 25].…”
