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

Mycoplasma pneumoniae is a leading cause of pneumonia and is associated with asthma. Evidence links M. pneumoniae respiratory disease severity with interleukin-12 (IL-12) concentrations in respiratory secretions. We evaluated the effects of IL-12 therapy on microbiologic, inflammatory, and pulmonary function indices of M. pneumoniae pneumonia in mice. BALB/c mice were inoculated with M. pneumoniae or SP4 broth. Mice were treated with intranasal IL-12 or placebo daily for 8 days, starting on day 1 after inoculation. Mice were evaluated at baseline and on days 1, 3, 6, and 8 after therapy. Outcome variables included quantitative bronchoalveolar lavage (BAL) M. pneumoniae culture, lung histopathologic score (HPS), BAL cytokine concentrations determined by enzyme-linked immunosorbent assay (tumor necrosis factor alpha [TNF-alpha], gamma interferon [IFN-gamma], IL-1b, IL-2, IL-4, IL-5, IL-6, IL-10, IL-12, and granulocyte-macrophage colony-stimulating factor), and plethysmography, both before and after methacholine treatment. M. pneumoniae-infected mice treated with IL-12 (MpIL12 mice) were found to have significantly higher BAL M. pneumoniae concentrations than those of M. pneumoniae-infected mice treated with placebo (MpP mice) (P < 0.001). MpIL12 mice had higher BAL concentrations of IL-12, IFN-gamma, TNF-alpha, and IL-6, with differences in IL-12 and IFN-gamma concentrations reaching statistical significance (P < 0.001). Airway obstruction was statistically elevated in MpIL12 mice compared to that in MpP mice (P = 0.048), while airway hyperreactivity was also elevated in MpIL12 mice but did not reach statistical significance (P = 0.081). Lung parenchymal pneumonia subscores were significantly higher in MpIL12 mice (P < 0.001), but no difference was found for overall HPS, even though a strong trend was noticed (P = 0.051). Treatment of experimental M. pneumoniae pneumonia with intranasal IL-12 was associated with more severe pulmonary disease and less rapid microbiologic and histological resolution.
