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

objectivesLow Birth Weight (LBW) has an important role in the mortality and morbidity of neonates and the incidence of LBW may vary across different environments. The aim of this study was to determine the incidence and some related factors of LBW in Mazandaran province, Northern Iran.

methodsIn this longitudinal study, all live births that were born in 5 maternity hospitals in Mazandaran province, north of Iran in 2011, were evaluated. Data including birth weight, sex, maternal age, gestational age, living location, number of pregnancy and delivery, as well as multiple births were recorded in medical files. LBW neonates were compared with neonates whose birth weight was more than 2,500 gram (control group).

resultsOut of 3792 infants, 2.9% (CI 95%: 2.3-3.3) were of low birth weight. Sixty percent of the infants in the LBW group and 8.3% in the control group were preterm, (p<0.001). In the LBW group, 22.2% were multiple births, while 0.5% in control group were multiple births (p<0.001), but other variable distributions such as sex, living location and mother's age did not differ between the LBW and the control groups (p>0.05).

conclusionResults show that the incidence of LBW in Mazandaran was low and prevention of preterm labor, educational intervention programs for high risk can be effective in the prevention of low birth weight.
