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

backgroundLow birth weight is a significant index for survival, intrauterine growth, and mortality in infants. Thus, this study is aimed at determining the prevalence of low birth weight in Iranian infants through a systematic review and meta-analysis.

methodsThis study was performed by meta-analysis from January 2000 to December 2019. The studies relevant to the topic have been obtained through search in databases of Scopus, ScienceDirect, SID, Magiran, Barakat Knowledge Network System, Medline (PubMed), and Google Scholar. Heterogeneity of the studies has been assessed by the

resultsBy investigating 14 articles and 93924 infants, the total prevalence of low birth weight in infants in Iran was achieved at 8.5% (95% CI: 7.3-9.9%) according to the meta-analysis; the most prevalence of low birth weight was in infants in Hamedan at 19.1% (95% CI: 21.2-17.2%) in 2007, and the lowest prevalence of low birth weight was in infants in Tonekabon at 4.2% (95% CI: 3.4-5.2%) in 2005, and also, by increasing the sample size, the prevalence of low birth weight increases, by which the difference is statistically significant (

conclusionDue to the high prevalence of low birth weight in infants in Iran, health policy-makers must take effective attempts in order to reduce it in infants.
