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
objectivesBiologic treatments have revolutionized the management of PsA by significantly improving clinical manifestations and preventing structural damage. Both result in better quality of life and improved physical functioning. Since the introduction of the first TNF inhibitor (TNFi) in the early 2000s, therapeutic options for PsA are increasing steadily, and a new generation of biologics, including anti-IL-17 and anti-IL-23 strategies, allows distinct targeted approaches. The purpose of this study was to investigate whether the demographic, clinical and disease characteristics of PsA patients who are selected for first-line biologic treatment has changed over time since the introduction of biologics.
methodsPatients with a clinical diagnosis of PsA were included in the KU Leuven BioSPAR registry, a prospective cohort of SpA and PsA patients treated with biologics and targeted synthetic DMARDs (tsDMARDs), such as apremilast and Janus kinase inhibitors. Demographics, prior DMARD use, disease characteristics and disease activity parameters were recorded at the initiation of biologic treatment and subsequently every 3 months for the first 2 years and later every 6 months. The patient data were compared in three treatment periods, corresponding to availability of the first and second generation of TNFi and the third generation of biologics.
resultsAnalysis of 185 Caucasian patients with PsA from our prospective cohort showed longer disease duration and higher disease activity, with higher tender joint count, swollen joint count and CRP in the first period compared with the later time periods. The demographic characteristics and prior DMARD use did not change over time. Skin and nail psoriasis were more frequent in earlier compared with the later treatment periods. The bio-DMARD survival rate was similar in the early and later treatment periods.
conclusionThe population of patients selected for treatment escalation has changed over time since the introduction of biologics. Our results suggest that with years of experience, PsA patients might be considered earlier and for therapy intensification in patients with less active disease in comparison to profiles in the early days of biologic treatment.
