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

backgroundAlthough the perinatal mortality in low income countries is about five-folds higher than in the high income countries, little is known about the association of socio-demographic factors with perinatal mortality. National and small scale studies so far reported have shown very contradictory results. The objective of this meta-analysis was to assess the association of perinatal mortality with selected sociodemographic factors.

methodsA computer based literature search was conducted mainly in the databases of African Journals Online, MEASURE Demographic and Health Survey (DHS), Google Scholar, HINARI, PUBMED, MEDLINE and the Cochrane Library. The inclusion criteria were: 1) studies that assessed the perinatal mortality in developing countries in relation to socio-demographic predictors and 2) studies published in English and conducted after the year 1990. Subgroup meta-analyses of perinatal mortality were performed for mothers' age, residence, educational level and wealth status. Sensitivity analysis and heterogeneity testing were done.

resultsIn this meta-analysis, several inconsistent associations of perinatal mortality with the selected socio-demographic variables were observed in the primary studies level, both DHS and small scale studies. However, the overall odds ratio (OR) demonstrated statistically significant association of perinatal mortality with low maternal age (OR=1.2) and short birth interval (OR=1.4) but was not influenced by the mothers' residence, low educational level and household wealth index. Very consistently, the highest perinatal mortality rates reported when the birth intervals were either too short (<15 months) or too long (>39 months).

conclusionBecause of the disagreement among previous studies, the present study demonstrated a small effect size on the increased risk of perinatal mortality among women who were pregnant during teenage ages and gave birth too frequently or after a long interval. Therefore, to confirm the strong predictors of perinatal mortality, further studies on sociodemographic factors are needed.
