Impact of bariatric surgery on health care utilization and costs among patients with diabetes.
Article in Medical care, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 14 papers, 1 of them a synthesis 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
backgroundThe effect of bariatric surgery on health care utilization and costs among individuals with type 2 diabetes remains unclear.
objectiveTo examine health care utilization and costs in an insured cohort of individuals with type 2 diabetes after bariatric surgery. RESEARCH
designCohort study derived from administrative data from 2002 to 2008 from 7 Blue Cross Blue Shield Plans.
participantsSeven thousand eight hundred six individuals with type 2 diabetes who had bariatric surgery. MEASURES: Cost (inpatient, outpatient, pharmacy, and others) and utilization (number of inpatient days, outpatient visits, specialist visits).
resultsCompared with presurgical costs, the ratio of hospital costs (excluding the initial surgery), among beneficiaries who had any hospital costs, was higher in years 2 through 6 of the postsurgery period and increased over time [post 1: odds ratio (OR)=0.58; 95% confidence interval (CI), 0.50-0.67; post 6: OR=3.43; 95% CI, 2.60-4.53]. In comparison with the presurgical period, the odds of having any health care costs was lower in the postsurgery period and remained relatively flat over time. Among those with hospitalizations, the adjusted ratio of inpatient days was higher after surgery (post 1: OR=1.05; 95% CI, 0.94-1.16; post 6: OR=2.77; 95% CI, 1.57-4.90). Among those with primary care visits, the adjusted OR was lower after surgery (post 1: OR=0.80; 95% CI, 0.78-0.82; post 6: OR=0.66; 95% CI, 0.57-0.76).
conclusions: In the 6 years after surgery, individuals with type 2 diabetes did not have lower health care costs than before surgery.
