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
backgroundDiscomfort perceived by patients during an intensive care unit (ICU) stay may limit their function, well-being, and quality of life after their stay. This study creates a comprehensive questionnaire (EXPRIM) able to distinguish and quantify the recollection of discomfort and emotional suffering experienced during a stay in an ICU stay, and to assess its performance.
methodThe measurement properties of the questionnaire were tested in a first sample of 50 patients recruited between February and July 2024 in a tertiary ICU, using internal consistency, test-retest reliability, standard error of measurement (SEM), and construct validity. Content validity was also tested, in a second sample of 20 patients and 10 ICU healthcare providers recruited between April and June 2024 in a regional ICU, using face-to-face qualitative interviews based on a semi-structured interview guide assessing comprehensibility, relevance and comprehensiveness of the instruction and items.
resultsEXPRIM is a 30-item questionnaire developed in French and translated in English. Its total score ranges from 0 to 10, reflecting the weighting of discomfort versus suffering. The internal consistency was very good (Cronbach's alpha coefficient 0.81). The intra- and inter-examinator reliabilities were excellent (Intraclass Coefficient Correlation = 0.875 and 0.858, respectively). SEM ranged from -0.071 to 0.035. Good correlations were found between EXPRIM and other questionnaires measuring similar concepts. There was good evidence of content validity to explore recollection of the ICU stay.
conclusionsThe EXPRIM questionnaire is a new tool with excellent psychometric properties to quantitatively assess the ICU experiences survivors recall after discharge. It is a promising tool to explore the extent of discomfort and emotional suffering during an ICU stay and to compare experiences between patients or populations.
