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

backgroundHelicobacter pylori, a widespread infection particularly in developing countries has been associated with many adverse effects during pregnancy including hyperemesis gravidarum, neural tube defects in newborns, intrauterine fetal growth restriction and miscarriage. We sought to document the effects of H. pylori infection on birth weight in a low-income setting in Kampala, Uganda.

methodsThis was a prospective cohort study conducted in Kampala between May 2012 and May 2013. The participants were H. pylori positive and H. pylori negative HIV negative primigravidae and secundigravidae. Recruitment was at ≤18 gestation weeks and follow up assessments were carried out at 26 and 36 gestation weeks and soon after delivery. H. pylori infection was determined using H. pylori stool antigen test. Maternal weight and height were measured, and body mass index (BMI) and gestational weight gain were calculated. Only term and live babies were considered. Low birth weight (LBW) was defined as a birth weight of <2500 gram.

resultsA total of 221 participants were enrolled with mean ± standard deviation (SD) age of 20.9 ± 2.7 years. The mean ± SD gestation age at delivery was 39.4 ± 1.0 weeks. Primigravidae were 61.5 % (n = 188) and 52.9 % (n = 117) of the participants were positive for H. pylori infection. Low pre-pregnancy BMI (<18.5 kg/m(2)) was recorded in 14.6 % (n = 28) while 38 % (n = 73) had a height <156 cm at recruitment. Of the infants born to the participants, 13.6 % (n = 26) had low birth weight (<2500 gram). Independent predictors for LBW were the mother being positive for H. pylori infection (odds ratio, OR, 3.6, 95 % CI 1.1 - 11.5; P = 0.031) maternal height at recruitment <156 cm (OR 3.4, 95 % CI 1.4-8.2; P = 0.008) and maternal weight gain rates <0.3 kg/week during the 2(nd) and 3(rd) trimesters (OR 3.8, 95 % CI 1.0-14.1; P = 0.044).

conclusionH. pylori infection is associated with LBW among primigravidae and secundigravidae in Kampala, Uganda.
