Tissue Advanced Glycation End Product Accumulation and Its Association with Clinical and Laboratory Features, Inflammatory Indices, and Comorbidities in Rheumatoid Arthritis and Ankylosing Spondylitis: A Case-Control Study.

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
Advanced glycation end products (AGEs) accumulate under chronic inflammation and metabolic stress and may contribute to long-term tissue damage. Skin autofluorescence (SAF) enables non-invasive assessment of tissue AGE accumulation, but data in inflammatory rheumatic diseases remain limited. The present study evaluated AGE-SAF levels in patients with seropositive rheumatoid arthritis (RA) and ankylosing spondylitis (AS) and investigated their associations with disease activity, inflammatory markers, metabolic parameters, and comorbidities. Patients with RA and AS, along with healthy controls, were included. AGE-SAF was measured non-invasively. Disease activity was assessed using the Disease Activity Score in 28 joints (DAS28) and the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI). Between-group comparisons were performed both crudely and after multivariable adjustment for age, sex, and body mass index (BMI). Logistic regression and receiver operating characteristic (ROC) analyses were used to describe the exploratory discriminative performance of AGE-SAF, and propensity score analyses were conducted as sensitivity analyses to address baseline imbalance. In crude comparisons, AGE-SAF levels were higher in RA than in AS and controls, and higher in AS than in controls (
