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

objectiveThe objective of the study was to study the genetic risk factors of spontaneous preterm birth (PTB) in African Americans. STUDY

designCase-control analyses were performed using maternal and fetal deoxyribonucleic acid from 279 African American birth events (82 PTB and 197 term) and 1432 single-nucleotide polymorphisms from 130 candidate genes. Single-locus association and haplotype analyses were performed.

resultsThe most significant associations were in the maternal interleukin (IL)-15 (rs10833, allele P = 2.91 x 10(-4), genotype P = 2.00 x 10(-3)) gene and the fetal IL-2 receptor B (IL-2RB) (rs84460, allele P = 1.37 x 10(-4), genotype P = 6.29 x 10(-4)) gene. The best models for these markers were additive (rs10833, odds ratio [OR], 0.30; 95% confidence interval [CI], 0.14-0.62; P = 1.0 x 10(-3); rs84460, OR, 2.32; 95% CI, 1.47-3.67; P < 1.0 x 10(-3)). The largest number of significant associations was found in genes related to infection and inflammation. There were overall a larger number of significant associations in infants than in mothers.

conclusionThese results support a strong role for genes involved in infection and inflammation in the pathogenesis of PTB, particularly IL-12 and IL-12RB, and indicate that in African Americans there may be complementarity of maternal and fetal genetic risks for PTB.
