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

backgroundAnimal models of arthritis are frequently used to evaluate novel therapeutic agents. However, their ability to predict responses in humans is variable.

objectiveTo examine the time course of signalling molecule and gene expression in two models of arthritis to assist with selection of the model and timing of drug administration.

methodsThe passive K/BxN serum transfer and collagen-induced arthritis (CIA) models were studied. Activation of MAP kinase and interferon (IFN)-response pathways was evaluated by quantitative PCR and western blot analysis of ankle joints at various time points during the models.

resultsThe kinetics of gene expression and kinase phosphorylation were strikingly different in passive K/BxN and CIA. All three MAP kinases (ERK, JNK and p38) and upstream kinases were activated within days in passive K/BxN and declined as arthritis severity decreased. Surprisingly, IFN-regulated genes, including IRF7, were not induced in the model. In CIA, activation of ERK and JNK was surprisingly low and p38 phosphorylation mainly peaked late in the disease. IFN-response genes were activated during CIA, with especially prominent peaks at the onset of clinical arthritis.

conclusionsTiming of treatment and selection of CIA or passive K/BxN might have an important impact on therapeutic response. p38, in particular, increases during the late stages of CIA. ERK and JNK patterns are similar in passive K/BxN and rheumatoid arthritis (RA), while IFN-response genes in CIA and RA are similar. The dichotomy between RA and animal models could help explain the poor correlation between efficacy in RA and preclinical studies.
