| SFS improvement two or more | |
| SCS limited or no change | 1.0 |
| SCS deterioration two or more | 0.63 (0.20 to 1.96) |
| SCS improvement two or more | 3.93 (1.62 to 9.54) |
| Pseudo adjusted R2* | 8.1% |
| SFS change in overall house | |

| SCS improvement two or more | 1.01 (0.38 to 2.71) |
| PPB≥1 increase | |
| SCS limited or no change | 1.0 |
| SCS deterioration two or more | 1.39 (0.48 to 4.00) |
| SCS improvement two or more | 1.19 (0.35 to 4.12) |

↵* Reference category (dependent and independent variables) for these models is limited or no change (for SFS and SCS limited or no change=change of <2 points; and for PPB limited or no change=change of <1 PPB).
PPB, persons per bedroom; RRR, relative risk ratios; SCS, Surveyor Condition Score; SFS, Surveyor Function Score.
ORs for which the CI excludes 1 are shown in bold.
