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

objectivesThis study aimed to investigate the associations of combined parental low educational level and combined parental unemployment on the risk of preterm birth (PTB) in Korea.

methodsData on 427,857 singleton births were obtained from the National Birth Registration (NBR) database in 2003 and analyzed. Parental education and parental employment status were combined as exposure for analysis. Place of birth, sex, marital status, parental age and parity were included for analysis of unconditional multiple logistic regressions. PTB was defined as birth before a gestational age of 37 complete weeks.

resultsGroup of the lowest educational level, below high school, had the highest odds of PTB in both father and mother in multivariable analysis [odds ratio (OR) 1.15 and 1.16, respectively]. After combining parental educational status for the multivariable analysis, the highest probability of PTB was in families where both parents had below college level education (OR 1.22). As for paternal employment, the multivariable analysis showed an increased rate of PTB occurred where the father was unemployed (OR 1.11). After combining the employment status of both parents, the multivariable analysis revealed that PTB was only significant in families where both parents were unemployed (OR 1.09).

conclusionsWe found that combined parental low educational level and combined parental unemployment increased the likelihood of preterm birth.
