Table 3 Separate ordinal logistic regressions relating psychological factors and pain intensities at T1 to: 1) the number of pain sites among subjects reporting the same NPS at T1 and T2, 2) the number of pain sites decreased among subjects that reported a higher number of pain sites at T1, and 3) the number of pain sites increased among subjects that a higher number of pain sites at T2
Sub-sample: | Employees reporting stable number of pain sites (T1 NPS = T2 NPS) | Employees reporting decreased number of pain sites (T1 NPS > T2 NPS) | Employees reporting increased number of pain sites (T1 NPS < T2 NPS) | ||||||
|---|---|---|---|---|---|---|---|---|---|
