Table 1 Functional status in an adult population, as a function of individual symptoms and the number symptoms reported

From: Symptom load and functional status: results from the Ullensaker population study

   ΔR2 β(95%CI) Stand. Beta BIC
Model I NPS 0.249 0.69 (0.65-0.73) 0.51 15488
Model II NN-MS 0.350 0.68 (0.65-0.71) 0.60 14963
Model III NPS + NN-MS 0.392 0.45(0.43-0.46) 0.64 14796
Model IV Ind. musculoskeletal symptoms 0.260 Ind. Ind. 15450
Model V Ind. non-musculoskeletal symptoms 0.424 Ind. Ind. 14540
Model VI Ind. musculoskeletal + non-musculoskeletal symptoms 0.482 Ind. Ind. 14224
  1. Footnote: Functional ability is measured on four COOP-WONCA scales: physical fitness, feelings, daily activities, social activities. Symptoms are grouped in NPS (Number of pain sites), NN-MS (Number of non-musculoskeletal symptoms). ΔR2: Change in correlation coefficients contributed by the variable (removing effect of age); β: unstandardized regression coefficient with CI (Confidence interval); Stand. beta: Standardised beta values converted to the same scale for all variables. BIC (Bayesian Information Criterion): a measure of fit applicable for model selection, penalising for the number of variables in the model (low value indicates better fit). Ind.: each component has an individual value.
