The Association Between Body Mass Index and Acute Postoperative Pain in Bariatric Surgery Patients: A Prospective Cohort Study.

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
introductionThe rising global prevalence of obesity has established bariatric surgery as a key therapeutic option; however, postoperative pain management remains a challenge. This study investigated the influence of body mass index (BMI) stratification on acute postoperative pain in patients undergoing bariatric surgery.
methodsFifty-five patients aged 18-65 years with BMI ≥ 30 kg/m
resultsCompared with the O group, the SO group demonstrated a significantly higher pain tolerance threshold (4.1 ± 0.8 vs. 3.5 ± 1.0, P < 0.01), along with lower demand for PCA and reduced consumption of cumulative morphine milligram equivalents and flurbiprofen (P < 0.05). Notably, the primary outcome, the 24-h BPI score, showed no significant difference between the two groups. On postoperative days 1 and 3, tumor necrosis factor-α (TNF-α) levels were significantly lower in the O group, whereas no significant intergroup differences were observed in other inflammatory cytokines. No significant differences were observed in NRS or QoR-15 scores between the two groups.
conclusionBMI may be considered as a factor for stratifying postoperative analgesia, favoring multimodal, opioid-sparing strategies in patients with severe obesity who demonstrate higher pain tolerance and lower analgesic requirements.
