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

aimThe aim of this research was to study the effect of rabbit hemorrhagic disease virus (RHDV) on the host immune response by examining the cellular composition/pathology of lymphoid organs and serum levels of tumor necrosis factor-alpha (TNF-α) and interferon-gamma (IFN-γ). MATERIALS AND

methodsNine adult rabbits were inoculated with 1 ml of 10% infected liver homogenate, and three rabbits served as controls. The rabbit hemorrhagic disease (RHD)-induced animals were studied on 3 consecutive days post-infection. Diagnosis of RHD was made through routine hemagglutination tests and the polymerase chain reaction. Blood smears and tissue samples from bone marrow (BM), spleen, lymph nodes, and liver were analyzed for cell composition and cytopathology. Serum levels of TNF-α and IFN-γ were measured by enzyme-linked immunosorbent assay.

resultsRHD showed a decreased absolute cell count of blood as well as lymph nodes, spleen, and BM cell populations with marked left shift. This was seen as a progressive rise in immature and blast cells. Quantitative cellular changes were accompanied by an increase in specific inflammatory cytokines. Immunocytopathological alterations were evidenced by: Vacuolized, hyperactivated tissue macrophages, finding of Döhle bodies in neutrophils, and activated lymphocytes with increased nuclear-cytoplasmic ratio. Cytoplasmic eosinophilic viral inclusions found in tissue (liver, spleen, and BM) macrophages were shown for the 1

conclusionThese studies suggest that RHDV induces pathology in leukocytes due to hyperactivation with left shift (toward immature stages of the different cell lineages). Macrophages are increased in number and show an expressed cytopathic effect often accompanied by viral eosinophilic cytoplasmic inclusions. They also developed a secretory activation (increased levels of pro-inflammatory cytokines).
