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

backgroundRecent studies indicate that rapid advances in medical technology have led to a steady increase in intensive care unit (ICU) survivors. The stressful experience of admission can lead to a series of symptoms in family caregivers of ICU patients, which is referred as Post-Intensive Care Syndrome‑Family (PICS‑F). However, existing tools are single-domain assessments and can only cover a portion of the four main domains of PICS-F. A comprehensive evaluation requires the combined use of multiple scales, which may make the process complex and time-consuming. Therefore, this study aims to develop and validate the PICS‑F Scale as an early screening tool for the risk of PICS‑F that covers physical, mental, cognitive, and social domains in family caregivers of adult ICU survivors.

methodsThe initial item pool was generated through a literature review. Two rounds of the modified Delphi survey were conducted by a multidisciplinary panel of experts. Psychometric evaluation was conducted using data from 468 family caregivers of ICU survivors who were recruited from two general hospitals in Shandong Province, China, from March to May 2025. Validity was assessed via exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Cronbach's α was used to assess the internal consistency. Criterion validity was assessed by calculating the correlation coefficient with the 36-Item Short Form Health Survey questionnaire (SF-36) used as the criterion measure.

resultsThe final PICS-F Scale contains 22 items. EFA revealed a four-factor structure, corresponding to physical, mental, cognitive, and social dimensions, which explained 76.33% of the total variance. CFA showed satisfactory fit indices (SRMR = 0.075, RMSEA = 0.090, TLI = 0.917, and CFI = 0.927). The scale showed great internal consistency (Cronbach's α = 0.934; subscales: 0.891-0.958). With respect to criterion validity, the correlation between the PICS-F Scale and SF-36 was r = -0.723 (p < 0.001).

conclusionsThe scale is a valid and reliable early screening tool for rapidly identifying family members at high risk of PICS‑F in Chinese language settings. It can be used in the early phase after ICU survivors are transferred out of the ICU.
