Effect of low-dose esketamine combined with labor analgesia on postpartum depressive symptoms following spontaneous labor: a randomized controlled trial.

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
Background: Postpartum depression (PPD) poses significant risks to maternal and infant well-being. This study aimed to assess the effect of low-dose epidural esketamine combined with labor analgesia on postpartum depressive symptoms and pain scores in women undergoing spontaneous labor. Methods: A randomized controlled trial was conducted with 299 participants assigned to three groups: Group A (esketamine 0.5 mg/kg + labor analgesia), Group B (labor analgesia alone), and Group C (no analgesia). The primary outcome was the Edinburgh Postnatal Depression Scale (EPDS) score at 42 days postpartum. Secondary outcomes included Visual Analogue Scale (VAS) pain scores and serum hormone levels. Results: Overall, EPDS scores were low across the cohort. At 42 days postpartum, no statistically significant difference in EPDS scores was observed between the esketamine group and the analgesia-only group (Group A: 1.97 ± 1.74 vs. Group B: 2.01 ± 1.68). The mean difference was -0.03 (95% CI: -0.46 to 0.39, Conclusion: In this low-risk cohort with low baseline depressive symptoms, the addition of low-dose esketamine to labor analgesia did not result in a significant reduction in EPDS scores at 42 days compared to labor analgesia alone. These findings suggest that the potential benefits of esketamine might be limited in populations with a low risk of PPD, and future studies focusing on high-risk groups are warranted.
