| S pneumoniae colonisation density, log10 copies per μL | |||
| Day 0 | 1·17 (0·02–2·08) | 1·21 (0·06–2·08) | 0·73 |
| Day 7 | 1·43 (0·44–2·32) | 1·18 (0·05–2·32) | 0·084 |

Data are n (%) or median (IQR).
*
Comparisons of carriage rates between groups done using the χ2 test. Cross-sectional comparisons of S pneumoniae density between groups at each timepoint were done using the Mann-Whitney U test.
