Extended Data Fig. 1: Regression analysis for intra-cage ammonia as a function of cage occupancy.

From: Rapid ammonia build-up in small individually ventilated mouse cages cannot be overcome by adjusting the amount of bedding

Extended Data Fig. 1

Best-fit regressions are shown for both cage Types (II, in green; and III, in blue) over the same housing density range (data from Experiment 1). Breeding cages have been excluded from the analysis. On the right, the regressions are shown individually, with the 95% confidence interval for the regression lines (with p-values listed for the associated analysis of variance) for a less cluttered view. Note that statistical testing was carried out as linear regression analysis of log-transformed data, whereas the data is here shown in a semi-log plot.
