1 · What the graph read from it

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.

2 · The registry

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

backgroundDifficult to manage (D2M) axial spondyloarthritis (axSpA) is an evolving clinical concept. We aimed to assess the prevalence, predictors and long-term outcomes of D2M axSpA.

methodsProspective single center cohort study of axSpA patients starting targeted agents (01/01/2007 until 28/02/2024). The ASAS criteria were applied to classify D2M. Baseline parameters were assessed as predictors of D2M development by multivariate logistic regression models. To identify comorbidity clusters and their contribution to D2M, a K-means cluster analysis on binary indicators of most prevalent chronic illnesses was performed. Long-term functional evolution and adverse events' rate were compared between D2M and non-D2M.

resultsOut of 434 patients, 50 (11.5%) developed D2M disease. Compared to non-D2M, they had higher disease activity at baseline (p = 0.01) and failed to improve at 6 months (p < 0.0001), while dyslipidemia, osteoarthritis and fibromyalgia were more prevalent (p < 0.0001). Independent predictors for developing D2M axSpA were the presence of fibromyalgia (OR 3.55), osteoporosis (OR 5.67) and dyslipidemia (OR 2.70), while two clusters of comorbidities ("chronic pain syndromes" and "metabolic") significantly contributed to D2M (OR 2.52 and OR 3.30; p = 0.010 and 0.013 respectively). During a total follow-up period of 2312 patient-years, D2M patients developed higher functional impairment and had more serious adverse events and hospitalizations (p = 0.016) compared to non-D2M patients.

conclusion11.5% of axSpA patients developed D2M disease and showed adverse long-term outcome compared to non-D2M. While D2M patients had at baseline higher disease's burden, comorbidities mostly related to chronic pain syndromes predicted D2M development, supporting their significance for D2M axSpA evolution.
