Efficacy and safety of ixekizumab treatment in patients with axial spondyloarthritis: 2-year results from COAST.
Article in RMD open, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03129100 (A Multicenter, Long-Term Extension Study of 104 Weeks, Including a Double-Blind, Placebo-Controlled 40-Week Randomized Withdrawal-Retreatment Period, to Evaluate the Maintenance of Treatment Effect of Ixekizumab), which is not on this map.

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.

Abstract
objectivesTo study the efficacy and safety of ixekizumab (IXE) in patients with radiographic (r-) and non-radiographic (nr-)axial spondyloarthritis (axSpA) for up to 116 weeks.
methodsCOAST-Y (NCT03129100) is the 2-year extension study following COAST-V, COAST-W and COAST-X. Patients were treated with either 80 mg IXE every 4 weeks or 2 weeks, as assigned in the originating studies. Efficacy was assessed in all participants continuously treated with IXE through week 116 and in subgroups based on disease subtype and dosing. Missing data were handled by non-responder imputation for categorical variables and modified baseline observation carried forward for continuous variables. Safety data were analysed in all patients having received ≥1 IXE dose.
resultsOf 932 patients who received ≥1 IXE dose, 773 enrolled in COAST-Y (82.9%); 665 of which (86.0%) completed week 116. Of 352 continuously treated patients, the proportion achieving Assessment of Spondyloarthritis International Society (ASAS40) at week 52 was 51.4%, which increased to 56.0% at week 116. The proportion of patients achieving ASAS40 at week 116 was 64.9% and 57.7% for biological disease-modifying antirheumatic drug (bDMARD)-naïve patients with r-axSpA and nr-axSpA, respectively, and 47.0% for TNFi-experienced patients. The proportion of patients achieving Ankylosing Spondylitis Disease Activity Score <2.1 through week 116 was 57.0% and 52.9% for bDMARD-naïve patients with r-axSpA and nr-axSpA, respectively, and 33.6% for TNFi-experienced patients. Incidences of treatment-emergent adverse events and serious adverse events were consistent with previous reports.
conclusionIXE treatment led to sustained long-term improvements in patients with axSpA, with similar efficacy for r-axSpA and nr-axSpA, and for patients receiving the approved every 4 weeks dose. The safety profile of IXE was consistent with previous reports. No new safety signals were identified.
