Use of prescribed opioids before and after bariatric surgery: prospective evidence from a U.S. multicenter cohort study.
Observational study in Surgery for obesity and related diseases : official journal of the American Society for Bariatric Surgery, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04073056 (Quadratus Lumborum II Block vs Conventional Therapy Alone For Laparoscopic Sleeve Gastrectomy), which is not on this map. Cited by 40 papers, 3 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.

Abstract
backgroundLimited evidence suggests bariatric surgery may not reduce opioid analgesic use, despite improvements in pain.
objectiveTo determine if use of prescribed opioid analgesics changes in the short and long term after bariatric surgery and to identify factors associated with continued and postsurgery initiated use.
settingTen U.S. hospitals.
methodsThe Longitudinal Assessment of Bariatric Surgery-2 is an observational cohort study. Assessments were conducted presurgery, 6 months postsurgery, and annually postsurgery for up to 7 years until January 2015. Opioid use was defined as self-reported daily, weekly, or "as needed" use of a prescribed medication classified as an opioid analgesic.
resultsOf 2258 participants with baseline data, 2218 completed follow-up assessment(s) (78.7% were female, median body mass index: 46; 70.6% underwent Roux-en-Y gastric bypass). Prevalence of opioid use decreased after surgery from 14.7% (95% CI: 13.3-16.2) at baseline to 12.9% (95% CI: 11.5-14.4) at month 6 but then increased to 20.3%, above baseline levels, as time progressed (95% CI: 18.2-22.5) at year 7. Among participants without baseline opioid use (n = 1892), opioid use prevalence increased from 5.8% (95% CI: 4.7-6.9) at month 6 to 14.2% (95% CI: 12.2-16.3) at year 7. Public versus private health insurance, more pain presurgery, undergoing subsequent surgeries, worsening or less improvement in pain, and starting or continuing nonopioid analgesics postsurgery were significantly associated with higher risk of postsurgery initiated opioid use.
conclusionAfter bariatric surgery, prevalence of prescribed opioid analgesic use initially decreased but then increased to surpass baseline prevalence, suggesting the need for alternative methods of pain management in this population.
