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

objectiveTo examine the effects on mucosal selective transport of polymeric IgA (pIgA) and the ability of exogenous pIgA to provide protection despite altered mucosal transport. SUMMARY BACKGROUND DATA: Parenteral nutrition significantly impairs established antipseudomonal immunity and IgA-mediated antiviral immunity in association with gut-associated lymphoid tissue mass atrophy. Lack of enteral feeding also induces mucosal effects.

methodsAfter immunization, nasotracheal levels of influenza-specific IgA were measured in cannulated mice randomized to chow feeding or parenteral nutrition. Nonimmune animals were randomized to chow or total parenteral nutrition, and after 5 days of diet were given a mixture of two antiinfluenza monoclonal antibodies, pIgA and IgG. Four hours after injection, nasal washes were collected and influenza-specific antibody levels were determined by enzyme-linked immunosorbent assay to calculate the selective transport index of IgA relative to IgG. In the final experiment, immunized animals were randomized to chow or parenteral feeding, and after 5 days, parenterally fed animals received either normal mouse serum or antiviral pIgA before viral challenge. Viral shedding was measured at 42 hours after challenge.

resultsParenteral nutrition significantly reduced virus-specific IgA in nasotracheal washes. Parenteral nutrition depressed the selective transport index, demonstrating impaired mucosal transport of pIgA. Parenterally fed animals given specific antiviral pIgA but not normal mouse serum eliminated virus from the airway and regained mucosal protection, demonstrating adequate residual transport for immunity if adequate pIgA is present.

conclusionAlthough both decreased IgA production due to gut-associated lymphoid tissue atrophy and impaired mucosal transport occur when enteral feeding is not provided, residual transport can provide antiviral protection if exogenous antiviral pIgA is available. Production, rather than transport, may be the most important factor in maintaining established respiratory tract IgA-mediated immunity.
