Helicobacter pylori eradication therapy in obese patients undergoing gastric bypass surgery--fourteen days superior to seven days?
Article in Obesity surgery, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05449028 (Helicobacter Pylori Eradication Therapy in Portugal), which is not on this map. Cited by 9 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.

Abstract
backgroundThe high prevalence of Helicobacter pylori (HP) in our obese population undergoing Roux-en-Y bypass gastric surgery (69.4%) and the concern that it may exacerbate postoperative foregut symptoms and increase gastric cancer risk led us to adopt a policy of HP systematic eradication in this group of patients. Our aim, in obese patients undergoing bypass gastric surgery, was to compare effectivity of 7- and 14-days clarithromycin-based triple therapy as the first-line treatment for HP eradication.
methodsThree hundred seventy-three patients [mean age 41.2 ± 10.3 years; 313 women (83.9%)] were HP positive determined by histology or urea breath test. In 2005, 94 patients (Group A) were treated with a 7-days triple therapy-proton pump inhibitor (PPI) b.i.d., clarithromycin (CL) 500 mg b.i.d., and amoxicillin (AMX) 1,000 mg b.i.d. Since 2006, 279 patients (Group B) were treated with a similar 14-days drug regimen-PPI b.i.d., CL 500 mg b.i.d., and AMX 1,000 mg b.i.d. Posttreatment HP status was assessed by C13 urea breath test 4-6 weeks after the end of therapy.
resultsThe eradication rates were 67.0% (Group A) and 79.9% (Group B). The eradication rate achieved with 14-days triple therapy was significantly higher than with 7-days triple therapy (OR = 1.96; 95% CI: 1.16-3.30; p = 0.016).
conclusionsA 14-days triple therapy is more effective than 7-days triple therapy suggesting this regimen should be the first-line therapy for HP eradication in Portuguese obese patients undergoing bypass gastric surgery.
