The effects on oxidative DNA damage of laparoscopic gastric band applications in morbidly obese patients.
Trial report in Canadian journal of surgery. Journal canadien de chirurgie, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundObesity may induce oxidative stress, causing oxidative damage of DNA. We examined associations between decreasing serum and urinary 8-hydroxy-2'-deoxyguanosine (8-OHdG) levels and weight loss in morbidly obese patients before and 6 months after laparoscopic adjustable gastric banding (LAGB).
methodsWe compared patients who had surgery for morbid obesity with healthy, nonobese controls. Urine and fasting blood samples were collected once from the controls and from the morbidly obese patients before and 6 months after the LAGB. The serum and urinary 8-OHdG levels were evaluated in these groups using an enzyme-linked immunosorbent assay kit.
resultsWe included 20 patients who had surgery for morbid obesity (8 men, 12 women, mean body mass index [BMI] 46.82 ± 4.47) and 20 healthy, nonobese people (10 men, 10 women, mean BMI 22.52 ± 2.08) in our study. There was no significant difference in serum 8-OHdG levels between the groups, whereas urinary 8- OHdG levels were significantly higher in morbidly obese patients than in controls. Weight, BMI and serum and urinary 8-OHdG levels were significantly decreased in morbidly obese patients 6 months after LAGB.
conclusionThe LAGB provides efficient weight loss in patients with morbid obesity. The systemic oxidative DNA damage was increased by the morbid obesity, but this increase was not related to weight gain, and it was more evident in serum than urine samples. After LAGB for morbid obesity, the oxidative DNA damage declined both in serum and urine.
