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

Tertiary Lymphoid Structures (TLS) are considered as genuine markers of inflammation. Their presence within inflamed tissues or the tumor microenvironment has been associated with the local development of an active immune response. While high densities of TLS are correlated with disease severity in autoimmune diseases or during graft rejection, it has been associated with longer patient survival in many cancer types and more recently with positive responses to anti-PD-1 immunotherapy. Their efficient visualization and quantification within human tissues may represent new tools for helping clinicians in adjusting their therapeutic strategy. In clinical settings, the use of single-marker immunohistochemistry (IHC) protocols prevails in immune cell infiltration in formalin-fixed, paraffin-embedded (FFPE) tissues. In contrast, the development of automated multiplex immunofluorescence markings, i.e., 40-plex, requires very costly investments in equipment and analysis stations. Yet, employing two or more markers can enhance the characterization of immune infiltrates, particularly in the context of TLS. Besides the growing development of multiplex labeling approaches, imaging can also be used to overcome some technical difficulties encountered during the immunolabeling of tissues with several markers.This chapter describes IHC methods to visualize in human tissue (tumoral or not) the presence of TLS. These methods are based on the immunostaining of four TLS-associated immune cell populations, namely, follicular B cells, follicular dendritic Cells (FDCs), mature Dendritic Cells (mDCs), and Follicular Helper T cells (T
