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

backgroundThis study was performed to provide information on the frequencies of Rh antigens, alleles, phenotypes, and haplotypes from our region in India and to compare them with those from other races. MATERIALS AND

methodsThis observational study was conducted on blood donors from March 2009 to August 2011 using a fully automated system for Rh typing of blood cells. The data were collected and calculations done to determine the antigen, phenotypes, allele and haplotype frequencies. The chi square test was used for comparisons between the results of our study and those of other studies.

resultsA total of 51,857 donors were included in this study. The most common Rh antigen found was "e". DCCee was the most prevalent phenotype in our study with the phenotype distribution being significantly different between our study and other studies from different regions of the world. DISCUSSION: We have determined the prevalence of Rh antigens and Rh phenotypes in the North Indian blood donor population and derived the allele and haplotype frequencies in the same population. The Rh blood group distribution in this population was different from that in other populations.
