Impact of surgery after injury on SDNN and posttraumatic stress disorder development over two years.
Article in Scientific reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
This study examined the modifying effects of surgery status on the association between the Standard Deviation of NN Intervals (SDNN) of the heart rate variability and the post-traumatic stress disorder (PTSD) development. Participants with physical injury were recruited from a trauma center and followed for two years. Baseline assessment included SDNN and surgery status. Socio-demographic and clinical covariates were collected. PTSD was diagnosed at 3, 6, 12, and 24 months post-injury using the Clinician-Administered PTSD Scale for DSM-5. Logistic regression analyses were performed. Among 538 participants, 58 (10.8%) developed PTSD during the study, with prevalence rates of 8.4% at 3 months, 6.5% at 6 months, 4.7% at 12 months, and 2.5% at 24 months. A significant modifying effect was found that lower SDNN were significantly associated with PTSD in non-surgical patients but not in surgical patients, with significant interaction terms. This pattern was observed from 3 to 12 months but not at 24 months. Surgery-dependent associations between SDNN and PTSD development were observed, highlighting the need for tailored PTSD prevention strategies considering SDNN and surgery status.
