Translation, cultural adaptation, reliability, and validity of the Persian version of the Constipation Severity Instrument.

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
Aim: The aim of this study was to translate and cross-culturally adapt the Constipation Severity Instrument (CSI) and assess its reliability and validity in the Iranian Persian language with chronic functional constipation. Background: Chronic functional constipation is a common complaint characterized by a range of symptoms. The use of a validated tool adapted to the culture is an important part of the treatment process. Methods: CSI was translated into Persian language according to Beaton's guidelines. One hundred and twenty-five patients with chronic functional constipation, according to ROME IV criteria, completed the questionnaires. Face validity was assessed in two qualitative and quantitative forms (impact score), internal consistency and test-retest reliability were assessed by Cronbach's alpha coefficient and intraclass correlation coefficient (ICC), respectively. Convergent validity was assessed by correlating the total scores of the CSI and the WCSS. The floor/ ceiling effects of the questionnaire were also assessed. Results: The impact score of all questions was greater than 1.5. The Cronbach's alpha coefficient for the total score was 0.90 and the ICC was 0.90. The total score of the CSI was significantly correlated with the total score of the WCSS (Spearman's p=0.74). No floor/ceiling effects were found. Conclusion: The Persian version of the CSI is a reliable and valid tool that can be used for psychometric evaluation. Clinicians can also benefit from this questionnaire when assessing treatment outcomes in Iranian patients.
