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

Linkage mapping in a backcross of {Brown Norway [BN/Crl (BN)] × ZUC-Lepr (faSte) (ZUC)} × ZUC identified a male-specific quantitative trait locus (QTL) for urinary albumin excretion (UAE) on rat chromosome 1. A homozygous ZUC.BN-(D1Rat42-D1Rat90)/Ste congenic was produced containing BN donor alleles from 135 to 276 Mb from chromosome 1 on the ZUC background. We observed threefold higher urinary albumin-to-creatinine ratios (ACR) in 15-wk-old Zucker background strain males than in same sex and age congenic animals when both strains are also homozygous for the ZUC leptin receptor fatty mutation (Lepr (faSte)) (P < 0.0001). We then linkage mapped within the donor region without confounded effects from other chromosomes. Phenotypes were collected in 248 F2 male rats in a population made by crossing parents heterozygous for both the BN donor region and ZUC Lepr (faSte). Significant interactions were observed between the Lepr genotype and chromosome 1 QTL for six renal traits: urine volume, UAE at 10 and 15 wk, ACR, right kidney weight, and plasma urea nitrogen. A few traits, such as UAE and ACR, exhibit a second peak at the distal end of the chromosome. Hydronephrosis exhibited one or two QTLs contingent on adjustment for body weight. The results now demonstrate at least two sets of coincident traits with different correlations to kidney function.
