Cure rate of Helicobacter pylori infection in Egyptian children related to CYP2C19 gene polymorphism.
Article in Indian journal of gastroenterology : official journal of the Indian Society of Gastroenterology, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
objectivesThis study was done in order to investigate the effect of CYP2C19 genetic polymorphism on the cure rate of children who received proton pump inhibitors (PPI)-based triple therapy for treating Helicobacter pylori (H. pylori) infection.
methodsParticipants included 100 children with H. pylori-positive gastritis diagnosed by endoscopy and biopsy in addition to H. pylori stool antigen test. Cure rate was assessed after 1 month of completion of a triple treatment course for 14 days. CYP2C19 polymorphism was analyzed by the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method.
resultsResults showed that cases with a CYP2C19 genotypic status consistent with the heterozygote extensive metabolizers (HetEMs) had a higher cure rate of H. pylori when compared with the homozygote extensive metabolizers (HomEMs) although it was statistically nonsignificant (84.6 vs. 69.2). In addition, the poor metabolizers (PMs) had a higher cure rate compared with those of the HomEMs which was also statistically nonsignificant (77.8 vs. 69.2). The cure rate was also higher among both the groups of HetEMs and PMs combined together compared to the HomEMs (OR = 2.15, p > 0.05). Comparing cases regarding their age, gender, and severity of H. pylori gastritis revealed a better cure rate in the age group >10 years, in females and in mild and moderate cases than other cases although statistically nonsignificant.
conclusionThe higher cure rate of H. pylori infection using the triple therapy for 2 weeks among HetEMs and PMs cases compared to the HomEMs might warrant a need for a therapy augmentation or modification for the HomEMs.
