Efficacy of Tofacitinib in Refractory Axial Spondylarthritis: A Dose-Escalation Study.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objectives The objective was to evaluate the efficacy and safety of escalating tofacitinib from 10 mg to 15 mg daily in NSAID-refractory axial spondyloarthritis (ax-SpA) patients with inadequate 12-week response to 10 mg. Methods This was a pragmatic, open-label, single-arm, dose-escalation study (24 weeks). 101 patients were enrolled (ITT); 88 completed both week-12 and week-24 assessments (evaluable). All started tofacitinib 10 mg daily. At week 12, those achieving ASDAS-CRP (Ankylosing Spondylitis Disease Activity Score - C-reactive protein) major improvement (MI; Δ≥2.0) continued 10 mg; non-responders escalated to 15 mg. Outcomes included ASDAS-CRP (Clinically Important Improvement (CII)/MI/inactive disease), Assessment of SpondyloArthritis International Society criteria (ASAS 20/40), Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Bath Ankylosing Spondylitis Functional Index (BASFI), Bath Ankylosing Spondylitis Metrology Index (BASMI), Ankylosing Spondylitis Quality of Life (ASQoL), and 36-Item Short-Form Health Survey (SF-36); safety was monitored per Common Terminology Criteria for Adverse Events (CTCAE) v5.0. Results Of the evaluable cohort (n=88), 57 (64.8%) achieved MI at week 12 and continued 10 mg; 31 (35.2%) escalated to 15 mg. By week 24, mean ASDAS-CRP improved from 4.4→1.7 (10 mg) and 4.0→2.2 (15 mg). In the escalation subgroup, ASDAS-CRP improved 3.0 ± 0.7→2.2 ± 0.7, BASDAI 3.9 ± 1.3→2.9 ± 1.2, and ASAS 20/40 responses rose to 93.5%/45.2%. Six patients discontinued due to AEs (5 transaminitis at ≤10 mg; 1 breast tumour). Rhinitis was more frequent with 15 mg (58.1% vs 31.6%). No TB, VTE, MACE, or deaths occurred. Conclusions In patients not meeting 12-week targets on 10 mg, escalation to 15 mg yielded additional clinically meaningful improvement with a safety profile generally comparable to 10 mg. Selective escalation may be a feasible treat-to-target strategy where alternatives are limited.
