Average number of days until complete resolution |
I 7.4 (SD 4.55); C 8.3 (SD4.35); Difference 0.9

3 of 10 patients received a second injection (= I). Lost to follow up: n=7 (I: n=4; C: n=3) |

Mean joint score after 1 to 2, 3 to 4, and 10 to14 days (5‐point scale: 0=total resolution, 1=improvement of > 50%, 2=improvement of <50%, 3=no change, 4=worsening of symptoms) |
I: 1.0 (SD 0.72) to 0.62 (SD 0.78) to 0.50 (SD 0 .16).
C: 1.5 (SD 0.85) to 0.65 (SD 0.63) to 0.20 (SD 0.37); Differences: 0.5 (p=0.24), 0.03 (p=0.94), and ‐0.30 (p=025) |
3 of 10 patients received a second injection (=I). 7 patients were lost to follow up (I: n=4; C: n=3) |

I = 44; C = 46 |
Mean decrease (mm on a VAS) per hour of pain at rest within the first 2 hours |
I ‐9.5 (SD 10.5); C ‐6.4 (SD 8.3); Difference 3.2
(95%CI ‐0.78 to 7.14), p=0.12 |
The difference in mean pain score was at no time more than 13mm, which was unlikely to be clinically relevant according to the authors. |

Mean decrease (mm on a VAS) per hour of pain during activity within the first 2 hours |
I ‐19.2 (SD 11.2); C ‐20.3 (SD 9.1); Difference ‐1.1 (95%CI:
‐5.34 to 3.24), p=0.63 |
The difference in mean pain score was at no time more than 13mm, which was unlikely to be clinically relevant according to the authors. |

Mean decrease (mm on a VAS) per day of pain at rest after 2 weeks |
I ‐0.7 (SD 1.2); C ‐0.3 (SD0.7); Difference 0.5 (95%CI: 0.03 to 0.89), p=0.04 |
The difference in mean pain score was at no time more than 13mm, which was unlikely to be clinically relevant according to the authors.
Lost to follow up: n=7 (I: n=0; C: n=7*) * had to stop the study after adverse effects |

Mean decrease (mm on a VAS) per day of pain during activity after 2 weeks |
I ‐2.9 (SD 2.0); C ‐1.7 (SD 1.6); Difference 1.2 (95%CI: 0.44 to 2.00). p=0.0026 |
The difference in mean pain score was at no time more than 13mm, which was unlikely to be clinically relevant according to the authors.
Lost to follow up: n=7 (I: n=0; C: n=7*) * had to stop the study after adverse effects |

I = 16; C = 15 |
Average number of days until complete resolution |
I 7.6; 7.9; Difference 0.3
p=0.89 |
4 of 16 patients required a second I‐injection, 9 of 14 a second C‐injection. 3 patients required a third C‐injection.
Lost to follow up: n=3 (I: n=0; C: n=3*) *2 because of <50% improvement after 3 C‐injections |
