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
BACKGROUND Currently, there is no published questionnaire translated in the Persian language for pruritus evaluation in patients with chronic liver disease. Therefore, it would be well worth having a valid and reliable Persian questionnaire for assessing pruritus with its different aspects. This study was designed to evaluate the validity and reliability of the translated version of the 12-Item Pruritus Severity Score (12-PSS) METHODS The patients with pruritus due to chronic liver disease, who referred to the liver clinic affiliated to Tehran University of Medical Sciences, were enrolled in this cross-sectional study. Following the forward-backward translation of 12-PSS into Persian, the content validity index (CVI) and its reliability were assessed. The patients were asked to respond to the visual analog scale (VAS) along with 12-PSS on their visits to evaluate the correlation between them. RESULTS 160 eligible patients were entered in the present study. The mean age was 46.03 (±13.05) years. The Cronbach's alpha for all domains of 12-PSS was 0.81-0.92 (average 0.89), which showed a strong consistency. The mean VAS and 12-PSS were 5.47±2.55 and 11.71 ± 5.25, respectively, and the correlation of VAS and 12-PSS was strong (
