Roles of Toll-like receptors 2 and 4 in mediating experimental autoimmune orchitis induction in mice.
Article in Biology of reproduction, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
The mammalian testis is an immunoprivileged site where male germ cell antigens are immunologically tolerated under physiological conditions. However, some pathological conditions can disrupt the immunoprivileged status and induce autoimmune orchitis, an etiological factor of male infertility. Mechanisms underlying autoimmune orchitis induction are largely unknown. The present study investigated the roles of Toll-like receptor 2 (TLR2) and TLR4 in mediating the induction of experimental autoimmune orchitis (EAO) in mice after immunization with male germ cell antigens emulsified with complete Freund adjuvant. Wild-type mice developed severe EAO after three immunizations, which was characterized by leukocyte infiltration, autoantibody production, and impaired spermatogenesis. Tlr2 or Tlr4 deficient mice showed relatively low susceptibility to EAO induction compared with wild-type mice. Notably, Tlr2 and Tlr4 double knockout mice were almost completely protected from EAO induction. Moreover, we demonstrated that TLR2 was crucial in mediating autoantibody production in response to immunization. The results imply that TLR2 and TLR4 cooperatively mediate EAO induction.
