Preliminary evaluation of Hitchens-Pike-Todd-Hewitt medium (HPTH) for detection of Group B Streptococci in pregnant women.
Article in Journal of clinical laboratory analysis, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
We aimed to compare Hitchens-Pike-Todd-Hewitt (HPTH) enrichment broth, Todd-Hewitt broth, and direct culture onto blood sheep agar containing selective antimicrobial (ABA) in screening Group B Streptococci (GBS) carriage in pregnant women. From April to June 2007, duplicate lower vaginal and duplicate anorectal specimens of 102 pregnant women at 35 weeks of gestation or more, who were assisted at Santa Casa de Misericórdia Hospital, Maringá, Paraná, Brazil, were screened by GBS using HPTH, Todd-Hewitt broth, and ABA. Twenty-five (24.5%) pregnant women had one or more positive culture for GBS in those media. The positive rate for each medium was 21.6% (22/102) in the HPTH, 12.8% (13/102) in ABA, and 11.8% (12/102) in Todd-Hewitt broth. HPTH seems to be a high satisfactory medium for screening GBS in vaginal and anorectal samples in pregnant women and additional studies would be interesting in a larger number of pregnant women and in different laboratories.
