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

Atlantic cod possess a unique immune system due to the loss of the MHC II antigen-presenting system and an extreme expansion of the MHC class I repertoire. Additional modifications are demonstrated within the innate immune system with losses and expansions of Toll-like receptor (TLR) genes. While Atlantic cod has lost its mammalian orthologs for plasma membrane localized TLRs, such as TLR1/6 and TLR2, it has expanded its intracellular TLRs including TLR7, -8, and -9. It has been hypothesized that teleost-specific TLR1-family related members TLR14 and TLR25 localize at the plasma membrane with the potential function to recognize bacterial surface components, compensating for the loss of cell surface TLRs. In this study, we have investigated the intracellular localization and function of Atlantic cod TLR14 and TLR25 using super-resolution microscopy in an Atlantic cod cell line and primary cells. Our results show that these TLRs localize to endolysosomes, and colocalize with LysoTracker, Rab5, and Rab7. Interestingly, TLR14 is also present at the plasma membrane, suggesting a function at the cell surface. In cells infected with
