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

objectiveTo establish cutoff values for the Arabic version of the Psoriatic Arthritis Impact of Disease (PsAID) questionnaire and examine their applicability across different cultural and ethnic backgrounds in Arab countries.

methodsThis study is a sub-analysis of the TACTIC initiative, a multicentric, multinational cross-sectional study. A total of 553 patients diagnosed with PsA from 13 Arab countries were included. Demographic and clinical data were collected, and disease activity was assessed using the Disease Activity in Psoriatic Arthritis (DAPSA) score. Psychometric scores, including the Patient Global Assessment (PGA), Health Assessment Questionnaire (HAQ), Patient Health Questionnaire (PHQ-4), and Fibromyalgia Screening Tool (FiRST), were also evaluated. PsAID thresholds were determined using Ward's method and the "Anchor-based Threshold Determination" according to changes in DAPSA categories.

resultsFive hundred fifty-three patients were included in the current analysis, with 59.0% being female. The mean age of the patients was 45.5 years (SD 13.15), and the mean disease duration was 8.8 years (SD 7.3). The mean PsAID was 3.8 (SD 2.3), and the mean DAPSA was 19.3 (SD 16.1). Two clusters were identified based on PsAID levels. Cluster 1 (n = 315) had a mean PsAID of 2.15, while cluster 2 (n = 238) had a mean PsAID of 6.12. Using Ward's method, the cutoff value was established at 4.1. A strong positive correlation was observed between DAPSA and PsAID scores (r = 0.718, p < 0.001). The anchor-based threshold analysis-based on shifts in DAPSA disease activity categories-identified a cutoff value of 3.8, which demonstrated good sensitivity and specificity in distinguishing between different levels of disease activity with an AUC of 0.83.

conclusionThe Arabic PsAID threshold was found to be consistent with the internationally established value of 4. These identified cutoff points can serve as valuable tools for evaluating the impact of psoriatic arthritis on patients' quality of life. Moreover, they can help guide more personalized treatment strategies across diverse populations and ethnic groups. Key Points • This study established cutoff values for the Arabic version of the Psoriatic Arthritis Impact of Disease (PsAID) questionnaire, confirming their alignment with international thresholds. •  Analysis of 553 patients from 13 Arab countries demonstrated robust correlations between PsAID and disease activity measures, with an optimal cutoff around 4. • These thresholds provide reliable tools for assessing disease impact and can support personalized treatment strategies across diverse Arab populations.
