Clinical Impact of Specific Extraocular Muscle Manipulation and the Oculocardiac Reflex on Postoperative Vomiting in Pediatric Strabismus Surgery: A Multicenter, Observational Study.
Observational study in Paediatric anaesthesia, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundStrabismus surgery, which is commonly performed in children, poses a high risk of postoperative vomiting. The current anesthesia guidelines for the prevention of postoperative vomiting in children are based on heterogeneous populations involving different types of surgery, and risk factors for postoperative vomiting in, specifically, the pediatric strabismus surgery population are unclear. Moreover, the effects of manipulating the deeply attached extraocular muscles and the oculocardiac reflex on this risk remain inconclusive.
aimTo evaluate the associations among inferior oblique muscle manipulation, the oculocardiac reflex, and postoperative vomiting in children with retrospectively collected data.
methodsThe study had a multicenter retrospective cross-sectional design and was conducted at three institutions (two tertiary-care children's hospitals and one pediatric-adult mixed community hospital). It included children aged < 18 years and without major comorbidities undergoing strabismus surgery. The primary exposure was inferior oblique muscle manipulation during surgery. The outcome of interest was postoperative vomiting or antiemetic medication usage within 24 h postsurgery or by discharge.
resultsAmong 3152 children postoperative vomiting occurred in 108/795 (13.6%) children with and 227/2357 (9.6%) without inferior oblique muscle manipulation (unadjusted odds ratio, 1.57; 95% confidence interval, 1.21-2.05; p = 0.001). Multilevel logistic regression analysis, adjusting for potential confounders and surgeon-related variance, revealed that inferior oblique muscle manipulation (adjusted odds ratio, 1.58; 95% confidence interval, 1.15-2.18; p = 0.005), but not the oculocardiac reflex (adjusted odds ratio, 1.06; 95% confidence interval, 0.76-1.48; p = 0.73), was associated with postoperative vomiting after adjusting for confounders.
conclusionsStronger preventive measures against postoperative vomiting are recommended in healthy children undergoing strabismus surgery with inferior oblique muscle manipulation. Additionally, inferior oblique muscle manipulation should be considered a potential confounder in future related studies. However, the oculocardiac reflex was not associated with postoperative vomiting in pediatric strabismus surgery.
