1 · What the graph read from 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.

2 · The registry

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

objectivesTo investigate the clinical, culture-based, histopathological and molecular aspects, genotyping and antibiotic susceptibility patterns of Helicobacter pylori (H. pylori) infection in dyspeptic pediatric patients.

methodsBiopsy samples from 245 dyspeptic pediatric patients were used, with four samples taken from each patient. Two samples were used for bacteriological/molecular analysis, while the others were used for histopathological examination. The presence of the virulence genes babA2, cagA, cagE, iceA and vacA in H. pylori isolates was analyzed by PCR. The antibiotic susceptibility of the isolates to amoxicillin, clarithromycin, levofloxacin, metronidazole, rifampicin and tetracycline was analyzed using the gradient method (E-test). Histopathologically, the presence of H. pylori was detected by immunohistochemical staining with anti-H. pylori antibodies.

resultsBacteriological analysis revealed that 70 (28.57%) of 245 samples were positive for H. pylori, with 71 H. pylori isolates obtained from 70 samples (two isolates from one sample). Molecular analysis showed 81 (33.06%) samples to be positive, while histopathological examination revealed that 76 (31.02%) were positive for H. pylori. Immunohistochemical staining showed that 64 (79%) of the 81 PCR-positive samples were positive. Antibiotic susceptibility testing showed resistance to metronidazole in 55 (77.46%) of 71 isolates, 19 (26.76%) to clarithromycin, 10 (14.08%) to levofloxacin and 4 (5.63%) to rifampicin. All isolates were sensitive to amoxicillin and tetracycline.

conclusionsThe data obtained are of great epidemiological importance. In addition, the results of antibiotic susceptibility test may help to select appropriate antibiotics for the treatment of the disease.
