Strain-specific differences in reovirus infection of murine macrophages segregate with polymorphisms in viral outer-capsid protein σ3.

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
Mammalian orthoreovirus (reovirus) strains type 1 Lang (T1L) and type 3 Dearing-RV (T3D-RV) infect the intestine in mice but differ in the induction of inflammatory responses. T1L infection is associated with the blockade of oral immunological tolerance to newly introduced dietary antigens, whereas T3D-RV is not. T1L infection leads to an increase in infiltrating phagocytes, including macrophages, in gut-associated lymphoid tissues that are not observed in T3D-RV infection. However, the function of macrophages in reovirus intestinal infection is unknown. Using cells sorted from infected intestinal tissue and primary cultures of bone-marrow-derived macrophages (BMDMs), we discovered that T1L infects macrophages more efficiently than T3D-RV. Analysis of T1L × T3D-RV reassortant viruses revealed that the viral S4 gene segment, which encodes outer-capsid protein σ3, is responsible for strain-specific differences in infection of BMDMs. Differences in the binding of T1L and T3D-RV to BMDMs also segregated with the σ3-encoding S4 gene. Paired immunoglobulin-like receptor B (PirB), which serves as a receptor for reovirus, is expressed on macrophages and engages σ3. We found that PirB-specific antibody blocks T1L binding to BMDMs and that T1L binding to PirB
