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

This article describes the development of IPUMS full count datasets of the censuses of enslaved inhabitants of the United States in 1850 and 1860 and their enslavers. These data are a result of two collaborations. The 1850 dataset stems from a collaboration between the Church of Jesus Christ of Latter-day Saints, whose volunteers transcribed the original manuscript forms, and IPUMS, which enhanced the raw data with editing, standardized coding procedures, constructed variables, and documentation. The 1860 dataset was the result of a similar collaboration between the genealogical company Ancestry and IPUMS. The article discusses the features of these datasets, their limitations, and suggests possible research uses.
