Recurrence of group B streptococcus colonization in successive pregnancies.
Article in Journal of perinatology : official journal of the California Perinatal Association, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
objectiveTo identify risk factors for group B streptococcus (GBS) colonization in a subsequent pregnancy using microbiological and clinical data from a prior pregnancy. STUDY
designA retrospective cohort study of women over a 10-year period, using laboratory records to identify women with GBS culture results available in two successive pregnancies.
resultOne thousand eight hundred and ninety-four women met eligibility criteria. Of these, 1293 were not GBS-colonized in either pregnancy, 198 were colonized in both pregnancies and 403 had discordant colonization status. GBS colonization in the index pregnancy was positively associated with multiparity, premature delivery and lower maternal age and negatively associated with chorioamnionitis. The strongest predictor of colonization in a subsequent pregnancy was colonization in the index pregnancy (50% likelihood if colonized compared with 14% if not in the index pregnancy, relative risk 3.6, confidence interval (CI)=3.1 to 4.3). GBS colonization in the subsequent pregnancy was independently associated with: GBS colonization in the index pregnancy (odds ratio (OR)=6.28; CI=4.91 to 8.05), preterm delivery in the index pregnancy (OR=1.80; CI=1.05 to 3.09) and prior early pregnancy loss (OR=1.15; CI=1.04 to 1.27).
conclusionGBS colonization in a prior pregnancy is informative of colonization in a subsequent pregnancy. These data support providing antimicrobial prophylaxis in unscreened parous women with known prior GBS colonization.
