Crude incidence rates per 100 patient years and HRs of major adverse cardiovascular events stratified by Janus kinase inhibitors
Overall patients | Cardiovascular risk patients | |||||||||
Number of treatment episodes | Patient years of follow-up | Number of events | Incidence rate (95% CI) | HR* (95% CI) | Number of treatment episodes | Patient years of follow-up | Number of events | Incidence rate (95% CI) | HR* (95% CI) | |
Baricitinib | 1416 | 2460.17 | 12 | 0.49 (0.25 to 0.85) | 0.58 (0.26 to 1.26) | 862 | 1543.25 | 11 | 0.71 (0.36 to 1.28) | 0.54 (0.24 to 1.22) |

*HR of major adverse cardiovascular events were estimated from the Andersen-Gill model applying inverse probability weighting. In all Andersen-Gill models, the number of previous DMARD substances was used as covariate in addition to the treatment effect due to exceeding the mean standardised difference threshold. Tumour necrosis factor inhibitors were selected as reference category.
DMARD, biologic disease-modifying antirheumatic drug; NR, not reported due to a low number of events.
