Effect of preoperative fasting on acute postoperative pain following cesarean section: a retrospective cohort study.
Article in Annals of medicine and surgery (2012), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Background: Preoperative fasting is a cornerstone of Enhanced Recovery After Surgery (ERAS) protocols in cesarean delivery, primarily aimed at reducing aspiration risk. However, its impact on acute postoperative pain remains unclear. This study addresses a critical evidence gap regarding whether adherence to ERAS-compliant fasting guidelines influences post-cesarean pain intensity. Methods: Data from 329 women who underwent cesarean sections at the hospital between March and December 2024 were retrospectively reviewed. Women were categorized based on adherence to ERAS fasting guidelines (≤8 h solids, ≤2 h clear fluids). The primary outcome was the 24-h postoperative Visual Analogue Scale (VAS) pain score. Univariate and multivariable linear regression models were used to assess the association between fasting compliance and VAS scores, adjusting for key covariates including age, body mass index, comorbidities, anesthesia type, surgical duration, and intraoperative morphine use. Results: Women adhering to ERAS fasting protocols had significantly lower mean 24-h VAS scores compared to non-adherent women (β = -0.6; 95% confidence interval: -1.2, -0.1; Conclusions: Adherence to ERAS fasting guidelines is associated with a modest but statistically significant reduction in acute postoperative pain after cesarean section. While the clinical relevance of a 0.6-point VAS difference may be limited, these findings support integrating standardized preoperative fasting into obstetric ERAS pathways as a safe, low-cost component of multimodal pain management and enhanced recovery.
