Helicobacter pylori DNA in dental plaques, gastroscopy, and dental devices.
Article in Digestive diseases and sciences, 2004. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
The role of dental plaque in the transmission of Helicobacter pylori (Hp) is unclear due to variability in the detection rates and techniques used. We used nested PCR to estimate the incidence of Hp in dental plaques of 24 dental hygienists. We found an unexpectedly high incidence (50%) of Hp DNA in dental plaques using sterilized dental probes. Additional treatment of sonication and SDS wash prior to sterilization of dental probes reduced the incidence to 13%. We used the treated probes to assess Hp presence in plaque samples of 47 patients visiting the dental clinic for teeth cleaning. Hp DNA was detected in 24% of cases. Since these data may reflect instrument contamination, we tested dental probes, endoscopes, and endoscopy forceps and found that 12.5-37.5% of them were contaminated. Consequently, dental plaques may be a candidate reservoir for Hp, medical equipment may contribute to Hp transmission, and sample collection techniques can bias the true prevalence of Hp in a population.
