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

Pathogenesis of Mycoplasma pneumoniae infection is considered to be in part attributed to excessive immune responses. Recently, a mycoplasma lipoprotein has been shown to induce nuclear factor kappaB (NF-kappaB) activation through toll-like receptor 1 (TLR1), TLR2 and TLR6. In this study, we examined the ability of lipoproteins from M. pneumoniae to activate NF-kappaB through TLR1- and TLR2-dependent, but TLR6-independent, pathways, and the active components responsible for the NF-kappaB activation through the TLR6-independent pathway were identified. The active lipoproteins were found to be MPN611 and MPN162 of M. pneumoniae (designated N-ALP1 and N-ALP2, respectively). Purified N-ALP1 and N-ALP2 from M. pneumoniae and triacylated partial synthetic lipopeptides of N-ALP1 and N-ALP2 augmented the levels of NF-kappaB induction through TLR1- and TLR2-dependent pathways, whereas diacylated partial synthetic lipopeptides of N-ALP1 and N-ALP2 activated NF-kappaB through TLR1-, TLR2- and TLR6-dependent pathways. These data suggest that N-ALP1 and N-ALP2 would be triacylated lipoproteins. The activity of N-ALP1 and N-ALP2 was decreased with a pretreatment of lipoprotein lipase, and partially decreased by protease treatment, indicating that the lipid moiety of N-ALP1 and N-ALP2 is critical for the NF-kappaB activation. Thus, triacylated lipoproteins derived from M. pneumoniae might activate NF-kappaB through TLR1 and TLR2, but not TLR6.
