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

A detailed analysis of the humoral response to Coxiella burnetii may provide insight into the pathogenesis of Q fever, a zoonosis caused by C. burnetii. The subclasses of C. burnetii-specific antibodies were determined by immunofluorescence in 20 patients with acute Q fever and 20 patients with chronic Q fever. Although immunoglobulin G1 (IgG1) and IgG3 antibodies were found in acute and chronic Q fever, neither IgG2 nor IgG4 was detected. The detection of IgG1 and IgG3 antibodies was not due to an increase of the IgG1 and IgG3 subclasses. Moreover, IgG1 and IgG3 antibodies were not correlated, suggesting that they may play different roles in Q fever.
