Estimated within-group marginal mean differences for primary and secondary outcome measures.
Outcome Time Baseline Mean Mean ± SE, p-Value Chiropractic + PT Sham + PT Primary: FMA At 4 weeks 40.9 64.1 ± 2.0, <0.001 * 58.0 ± 2.1, <0.001 * At 8 weeks 64.3 ± 2.4, <0.001 * 59.8 ± 2.4, <0.001 * Secondary: FMA-UE At 4 weeks 24.1 38.9 ± 1.7, <0.001 * 36.0 ± 1.8, <0.001 * At 8 weeks 40.3 ± 2.1, <0.001 * 37.3 ± 2.1, <0.001 * FMA-LE At 4 weeks 16.8 25.0 ± 0.8, <0.001 * 22.1 ± 0.9, <0.001 * At 8 weeks 24.2 ± 1.0, <0.001 * 22.4 ± 1.0, <0.001 * SS-QOL At 4 weeks 122.1 162.5 ± 7.2, <0.001 * 171.7 ± 7.4, <0.001 * At 8 weeks 190.6 ± 8.1, <0.001 * 174.0 ± 8.1, <0.001 * TUG At 4 weeks 23.7 20.5 ± 1.6, 0.047 * 21.7 ± 1.5, 0.2 At 8 weeks 21.3 ± 1.8, 0.2 20.4 ± 2.0, 0.1 mRS At 4 weeks 2.8 2.4 ± 0.2, 0.01 * 2.4 ± 0.2, 0.02 * At 8 weeks 2.2 ± 0.2, <0.001 * 2.1 ± 0.2, <0.001 * 5SST Baseline MB: 21.3 ± 2.1 MB: 22.7 ± 2.0 At 4 weeks 17.9 ± 2.1, 0.3 20.8 ± 2.0, 0.5 At 8 weeks 17.4 ± 2.3, 0.2 17.8 ± 2.6, 0.1 * denotes the null hypothesis is rejected. These marginal means were estimated by the statistical models by holding the baseline scores constant across the two groups, except in the case of 5SST, for which baseline means were also estimated by the respective model. Confidence intervals are presented in the supplementary file.
