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
Objective: This cross-sectional study aimed to identify latent profiles of pain catastrophizing among patients following cardiac surgery and to examine their concurrent associations with fear of pain, sleep quality, and psychological resilience. We further tested whether sleep quality and psychological resilience showed statistical indirect associations between pain catastrophizing profiles and fear of pain in a pre-specified cross-sectional model. Methods: This cross-sectional study included 468 patients who were assessed on postoperative days 3-5 after cardiac surgery at three tertiary Grade-A general hospitals in Zhejiang and Guangdong Provinces, China, between July 2024 and August 2025. Core variables were assessed using the Chinese Pain Catastrophizing Scale, the Simplified Chinese Fear of Pain Questionnaire-9, the Sleep Quality Questionnaire, and the Connor-Davidson Resilience Scale, respectively. Results: Latent profile analysis supported a three-profile solution with good classification accuracy (Entropy = 0.875), including low, moderate, and high severity pain catastrophizing profiles, accounting for 22.44%, 56.20%, and 21.36% of participants. The three profiles differed significantly in sleep quality (F = 24.624, P < 0.001), psychological resilience (F = 43.727, P < 0.001), and fear of pain (F = 798.921, P < 0.001). Relative to the low profile, both the moderate and high profiles positively predicted fear of pain (B = 0.962 and B = 1.944, respectively; both P < 0.001). In the cross-sectional indirect-effect model, sleep quality showed small but statistically significant indirect associations for both contrasts (moderate vs low: indirect effect = 0.026, 95% CI [0.004, 0.054]; high vs low: 0.035, 95% CI [0.005, 0.076]). Psychological resilience showed a statistically significant suppression-type indirect association only for the high- versus low-severity contrast (indirect effect = -0.058, 95% CI [-0.102, -0.020]). Conclusion: These findings underscore the clinical importance of early identification and severity-stratified management of pain catastrophizing in postoperative patients, with particular attention directed toward moderate- and high-severity subgroups.
