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
objectiveThis study aimed to explore the feasibility of the cognitive-behavioral model of COVID-19-related hypochondriasis among participants infected with the virus, with specific consideration of insomnia severity. Additionally, factors predicting post-infection insomnia were examined in participants without pre-existing sleep disturbances pre-COVID-19 infection.
methodsAn online study was conducted involving the general population infected with COVID-19. Data were collected on COVID-19 and participants' psychiatric and sleep disorder histories. Self-rating scales utilized included the Insomnia Severity Index (ISI), Obsession with COVID-19 Scale (OCS), Coronavirus Reassurance-Seeking Behaviors Scale (CRBS), Stress and Anxiety to Viral Epidemic-6 items (SAVE-6), Patient Health Questionnaire-2 items (PHQ-2), and Dysfunctional Beliefs about Sleep-2 items (DBS-2).
resultsAmong the 260 participants infected with COVID-19, mediation analysis revealed that SAVE-6 had a direct influence on OCS, while CRBS mediated this effect. Furthermore, a separate mediation model demonstrated that the impact of ISI on OCS was mediated by CRBS, PHQ-2, and SAVE-6. Logistic regression analysis conducted on 211 participants without prior sleep disturbances indicated that past psychiatric history, DBS-2, and PHQ-2 served as predictive factors for post-COVID sleep disorders.
conclusionThis study established a feasible hypochondriasis model, demonstrating the influence of insomnia on preoccupation with COVID-19, mediated by reassurance-seeking behavior, depression, and viral anxiety. Moreover, a history of psychiatric disorders, depression, and dysfunctional beliefs about sleep significantly contributed to the emergence of post-COVID sleep disorders.
