Is short-term therapy really sufficient to eradicate Helicobacter pylori infection?

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
objectiveThe aim of our study was to perform a systematic review and meta-analysis of the efficacy of short-term protocols for Helicobacter pylori eradication and to review the safety and adverse profiles of these eradication protocols.
methodsLiteratures were located through electronic searches by PubMed, Medline, ISI Web of Knowledge, and Cochrane Library using the relevant terms. Abstracts of important meetings were searched manually in some journal supplements. Additional bibliographies were identified from the reference lists of identified studies. Three independent reviewers systemically identified randomized controlled trials (RCTs) comparing short-duration protocols vs. 7-d proton pump inhibitor (PPI)-based triple protocols, as well as studies reporting eradication rates of short-duration protocols for H. pylori. Summary effect size was calculated as relative risk (RR) and 95% confidence intervals (CI) using Review Manager 4.2, and P<0.05 was defined as statistically significant in all analyses.
resultsAmong 90 abstracts retrieved, 15 studies were analyzed, including a total of 30 treatment regimens with 1856 subjects. Mean intention-to-treat (ITT) cure rates of 63.2% and 81.3% were achieved with short-term protocols and 7-d PPI-containing protocols, respectively. Per-protocol (PP)-based overall cure rates were 66.6% and 86.1%, respectively. Short-term therapy was inferior to 7-d triple regimen (P<0.00001). After sub-analysis, however, comparing the effects of > or = 3-d protocols and 7-d triple protocols, the cumulative ITT RR was 0.95 (P=0.26), and PP RR was 0.95 (P=0.10), without significant heterogeneity. Moreover, slightly fewer adverse-effects were found in short-term protocols.
conclusionsAlthough more economical, short-duration protocols are inferior to 7-d PPI-based triple protocols with regarding to eradication rate of H. pylori. Protocols of more than 3 d, however, may be equivalent to 7-d protocols.
