Early Postoperative Nausea and Vomiting After Bariatric Surgery: A Study of 8426 Patients from the Swedish Perioperative Registry (SPOR).
Observational study in Obesity surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04433676 (Risk of Early Postoperative Nausea and Vomiting), which is not on this 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.

Abstract
backgroundThe reported incidence of postoperative nausea and vomiting (PONV) after laparoscopic bariatric surgery is up to 60-80%. Hower, studies are limited, and larger studies are warranted. As PONV is usually evaluated in the post-anesthesia care unit (PACU), studying early PONV can be a valuable tool for exploring risk and associated factors for PONV.
methodsUsing prospectively collected data from the Swedish perioperative registry (SPOR) from 2016 to 2022, we explore the incidence and associated factors for early PONV after laparoscopic bariatric surgery. Laparoscopic gastric bypass and laparoscopic gastric sleeve procedures in adult patients (≥ 18 years) were included. The primary outcome was the incidence of PONV in the PACU. Secondary outcomes were factors associated with PONV, which were analyzed using a multivariate logistic regression model.
resultsIn total, 14,098 procedures were identified in the registry during the study period, and 8426 unique patients from 32 hospitals in Sweden were included in the final study cohort. PONV in PACU was present in 36% (n = 3018) of patients. Factors associated with early PONV were female sex, age, moderate-severe pain, gastric sleeve procedures, duration in PACU, and hospital.
conclusionsIn this national register-based cohort study, one third of patients experienced early PONV in the PACU after laparoscopic bariatric surgery. Several risk factors were associated with increased occurrence of PONV, and there was variability among hospitals in the incidence of PONV. CLINICALTRIALS: gov: NCT04433676.
