Anaesthetic Factors Affecting Outcome After Bariatric Surgery, a Retrospective Levelled Regression Analysis.
Observational study in Obesity surgery, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 29 papers, 2 of them syntheses that pooled it.
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
backgroundDeep neuromuscular block (NMB) and opioid-free anaesthesia (OFA) improve surgical workspace and reduce post-operative opioid consumption, but its impact on perioperative outcomes is unknown. This observational study compared complications and healthcare resource utilization after bariatric surgery, with or without continuous deep NMB or OFA.
methodsWe included all 9246 patients who underwent laparoscopic bariatric surgery at our institution from January 2009 to February 2017. Continuous clinical deep NMB was defined as receiving a continuous infusion of rocuronium with a dose of > 1 mg/kg IBW for each hour or sugammadex > 2 mg/kg total body weight at the time of reversal. We analysed the effect of continuous clinical deep NMB and OFA and covariates on 1 month post-operative complications using the Clavien-Dindo (CD) classification (grades II-V) and healthcare utilization (hospital length of stay [LOS], rates of reoperations within 1 week, high-dependency care unit admissions, and readmissions within 1 month). Covariates included experience of the attending anaesthesiologist, patient age, sex, body mass index, American Society of Anesthesiologists physical status score, obstructive sleep apnoea syndrome, diabetes, hypertension, surgery type, surgical team experience, and neostigmine use.
resultsOFA, continuous deep NMB, surgical and anaesthesia team experience, younger age, and surgery type were associated with fewer complications. OFA was associated with lower healthcare resource utilization. Reduced LOS was also associated with younger age, surgical team experience, and surgery type, but not continuous deep NMB.
conclusionContinuous deep NMB and OFA were associated with fewer complications after bariatric surgery.
