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
Introduction: Early detection of psoriatic arthritis (PsA) is critical to prevent joint damage and disability. The Psoriasis Epidemiology Screening Tool (PEST) and the Early Arthritis for Psoriatic Patients (EARP) questionnaire are established instruments for identifying PsA in patients with psoriasis. However, validated Polish versions were not available. This study aimed to translate and validate the Polish versions of both questionnaires. Material and methods: The translation process followed international guidelines. Two independent forward translations from English to Polish were performed by translators (P.K.K., K.M.T.), and a unified version was established by a third consultant (J.C.S.). This was followed by two independent back translations from Polish into English (A.Z., P.W.) to ensure accuracy. The back translations were presented to the authors of the original questionnaires. Cognitive debriefing was conducted with eight patients diagnosed with PsA to enhance clarity and cultural relevance. The final Polish questionnaires were then administered to 45 adult patients diagnosed with PsA, as defined by the Classification Criteria for Psoriatic Arthritis, who were recruited from three clinical centers. Participants completed the questionnaires twice within a 3-to-5-day interval. The obtained data were subjected to statistical analysis. Results: The Polish versions of PEST and EARP demonstrated adequate internal consistency, with Cronbach's α values of 0.712 for PEST and 0.771 for EARP. Test-retest reliability was robust, with intraclass correlation coefficient values of 0.731 and 0.730 for the respective questionnaires. No statistically significant differences were observed between the two assessments ( Conclusions: The validated Polish versions of the PEST and the EARP questionnaires are reliable instruments for screening PsA. Their implementation in clinical practice may facilitate early diagnosis and referral to rheumatology, thereby enhancing patient management in Poland.
