Odd Ratios denote chance of getting less happy. Sign of correlation reversed to fit standard notation in WDH
M-FH-c-sq-v-3-b OR = - s/ns T1-T2 CHANGE to Happy (vs Very happy)
- age 15 or less OR = 2.08 CI95[1.07.4.01]
- age 16-17      OR = 1.94 CI95[1.20-3,13]
- age 18 or more OR = 1.49 CI95[0.83-2.69]
