Isolated immunoglobulin G4 subclass deficiency in a child with bronchiectasis.
Article in Indian journal of pediatrics, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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.
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
Immunoglobulin G4 subclass deficiency is the most common IgG subclass deficiency, followed by immunoglobulin G2 deficiency. However, IgG2 deficiency is the most common IgG subclass deficiency associated with recurrent infections. Immunoglobulin G4 subclass deficiency occurs in association with other isotype deficiencies. Isolated IgG4 deficiency, however, is much less common. Although respiratory tract infections are the most common manifestation in isolated IgG4 deficiency, other mucosal surfaces may also be affected in IgG4 deficiency leading to diarrhea and recurrent giardiasis. The authors herein report a case of isolated immunoglobulin G4 subclass deficiency in a young girl presenting with bronchiectasis. The diagnosis was established after ruling out other causes of secondary and primary immunodeficiency.
