The regulatory role of sleep quality in the effect of preoperative intrusive thoughts on the fear of pain: structural equation modeling.
Article in BMC psychology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundTo investigate the regulatory role of sleep in the effect of preoperative intrusive thoughts on the fear of pain.
methodsA descriptive, cross-sectional study and complying with STROBE guidelines. The study included 209 patients hospitalized in a tertiary hospital during the preoperative period. Data were collected using a Patient Identification Information Form, the Fear of Pain Questionnaire-III, The Preoperative Intrusive Thoughts Inventory (PITI), and the Richards-Campbell Sleep Questionnaire (RCSQ).
resultsFemale gender and the severity of pain preoperatively were determined to have an effect on the fear of pain and preoperative intrusive thoughts (p < 0.05). The fear of pain was determined to be negatively correlated with sleep quality (r=-0.172, p < 0.05), and positively correlated with preoperative intrusive thoughts (r = 0.579, p < 0.001). Sleep quality (β=-0.165, p < 0.001) and preoperative intrusive thoughts (β = 0.850, p < 0.05) were determined to be predictive of the fear of pain. There was not observed to be any regulatory role of sleep quality in the effect of preoperative intrusive thoughts on the fear of pain (β = 0.001, p > 0.05).
conclusionThe preoperative intrusive thoughts of patients and their sleep quality affect the fear of pain. Identifying and controlling the factors affecting the fear of pain will reduce the postoperative pain levels of patients, prevent complications.
