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

Between October 1994 and October 1995, the number of birth defects per 1,000 live births in Al Basrah Maternity Hospital was 1.37. In 2003, the number of birth defects in Al Basrah Maternity Hospital was 23 per 1,000 live births. Within less than a decade, the occurrence of congenital birth defects increased by an astonishing 17-fold in the same hospital. A yearly account of the occurrence and types of birth defects, between 2003 and 2011, in Al Basrah Maternity Hospital, was reported. Metal levels in hair, toenail, and tooth samples of residents of Al Basrah were also provided. The enamel portion of the deciduous tooth from a child with birth defects from Al Basrah (4.19 μg/g) had nearly three times higher lead than the whole teeth of children living in unimpacted areas. Lead was 1.4 times higher in the tooth enamel of parents of children with birth defects (2,497 ± 1,400 μg/g, mean ± SD) compared to parents of normal children (1,826 ± 1,819 μg/g). Our data suggested that birth defects in the Iraqi cities of Al Basrah (in the south of Iraq) and Fallujah (in central Iraq) are mainly folate-dependent. This knowledge offers possible treatment options and remediation plans for at-risk Iraqi populations.
