^aDiagonal reference models were fitted with a logit link and odds ratios (ORs) were thus reported for all control variables. Model 4 did not include any indicator for social mobility (baseline for comparison); Model 5 included an indicator for any mobility (upward or downward); Model 5 included an indicator for upward mobility; and Model 6 included an indicator for downward mobility
^bWeights for social class of origin and destination are expressed as coefficients from 0 to 1
^cThese values are odds of reporting poor oral health among non-mobile adults at each social class
