Table 3 Results of the LMM model (N = 185 samples) testing the impact of sampling period on urinary neopterin levels (nmol/L corr. SG) in wild chimpanzees (N = 28).

From: Urinary neopterin levels increase and predict survival during a respiratory outbreak in wild chimpanzees (Taï National Park, Côte d’Ivoire)

  1. 1z-transformed to a mean of zero and standard deviation of one; mean (SD) of original variables were 17.61 (12.47) years and 11.08 (3.58) hours, respectively.
  2. The full model included sampling period (PRE, OB, POST), whether individuals survived, sex, age, collection time, and whether individuals were treated with an antibiotic shot as fixed effects. Individual was included as a random intercept effect with random slopes for age and collection time.
