Article in American journal of public health, 1993. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers, 1 of them a synthesis that pooled it.

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 examined hospital characteristics and hospital population risk factors and their associations with hospital-specific cesarean section rates in Washington State.

methodsData were obtained from 1987 birth certificates. The study population included all hospitals that had 12 or more singleton live births.

resultsHospital-specific cesarean section rates varied from 0% to 43% and were positively associated with proprietary ownership, size of delivery service, and the proportions of women who had complications or high-birthweight infants. The proportion of women who had late prenatal care was inversely associated with cesarean section rates. Although proprietary hospitals had higher cesarean section rates, their patient populations were lower risk than patients of public or teaching hospitals.

conclusionsVariation in cesarean section rates among hospitals cannot be fully explained by either hospital or patient population characteristics. A combined strategy may be necessary to lower unjustifiably high cesarean section rates.
