a Scheffé multiple comparison procedure (p < .05) was used to compare differences across groups. For each variable means with different numbers (1-3) are statistically different form one another and evaluated separately for CRP and SAA.
CRP means are adjusted for age, race/ethnicity, energy (kcal), NSAID (yes/no), and weight difference (kg), SAA means are additionally adjusted for arthritis (yes/no).
b Obese ≥35% Body Fat, not obese < 35% Body Fat.
c Current use of over-the-counter or prescription non-steroidal ant-inflammatory drugs (NSAID). Adjusted for age, ethnicity, energy (kcal), weight difference (kg).
d Sample size (n) represents number of non-obese and obese women in each stratum. e.g. 31 non-obese and 35 obese women who are non-users of NSAID. The same formatting in describing sample size is used for other strata.
e Adjusted for age, ethnicity, energy (kcal), NSAID (yes/no). Weight gain is >5% increase in bodyweight since baseline and weight loss is >5% decrease since baseline.
