Comparison of T cell response to vaccination in rheumatic patients treated with Janus kinase inhibitors and TNF inhibitors.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundJanus kinase inhibitors (JAKi) represent a well-established therapeutic option for the treatment of autoimmune diseases. However, there is a paucity of evidence regarding their impact on de novo immune responses to vaccinations. T cells may confer long-lasting immunity and cross-recognise evolving epitopes of new viral variants, as evidenced by the SARS-CoV-2 vaccination. Consequently, we investigated the de novo T-cell response to SARS-CoV-2 vaccination in patients with rheumatic diseases undergoing treatment with JAK inhibitors.
methodsCross-sectional study, conducted in an outpatient department. Patients with rheumatic disease who had received two vaccinations against SARS-CoV-2 while under therapy with JAKi (n = 22) or tumour necrosis factor-blocking biologicals (TNFi) (control group n = 16) were recruited. To evaluate the vaccine-induced T cell response, the patients' PBMCs were stimulated with SARS-CoV-2 spike protein peptides. The percentage of CD4
resultsA specific T cell response was detected in 11 out of 22 (50.0%) of patients in the JAKi cohort, compared to 13 out of 16 (81.3%) of the TNFi cohort (p = 0.088). Patients on JAKi had a lower percentage of CD4
conclusionsPatients on JAKi exhibited a compromised de novo T cell response to SARS-CoV-2 vaccination compared to TNFi patients. There is a need for further research on the effect of JAKi on T cell responses to vaccination.
