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

The stimulation of Toll-like receptors (TLRs) on macrophages triggers production of proinflammatory cytokines such as tumor-necrosis factor-α (TNF-α). The TNF production is mediated by a series of signaling events and subsequent transcriptional and post-transcriptional activation of the TNF gene. Termination of TLR-mediated cellular signaling is also important for a proper immunoresponse, since sustained cytokine expression can result in immune disorders. Here we identified that mixed-lineage kinase (MLK) 4 is a TLR4-interacting protein. Unlike previously characterized MLK group members, MLK4 cannot act as a mitogen-activated protein kinase kinase kinase (MAP3K) to mediate c-Jun N-terminal kinase (JNK), p38 or extracellular signal-regulated kinase (ERK) activation. Rather, MLK4 appears to be able to inhibit lipopolysaccharide (LPS)-induced activation of the JNK or ERK pathways, but does not have effect on LPS-induced p38 or NF-κB activation. The LPS-induced TNF production in MLK4 knockdown and overexpression cells were also increased and reduced, respectively. These data demonstrate that MLK4 is a negative regulator of TLR4 signaling.
