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

High-resolution characterization of antigen-specific T cell responses is essential for understanding cellular immunity to Chlamydia trachomatis infection in humans. This chapter describes two complementary flow cytometry-based approaches for measuring human antigen-specific T cell responses: intracellular cytokine staining (ICS) and activation-induced marker (AIM) staining. Both assays enable single-cell-level analysis following antigen stimulation but differ in their readouts. ICS quantifies functional cytokine production in response to short- or long-term stimulation, whereas the AIM assay identifies antigen-specific T cells based on transient surface expression of activation markers without fixation or permeabilization, preserving cells for downstream applications. Detailed protocols are provided for peripheral blood mononuclear cell (PBMC) thawing and preparation, short-term or long-term antigen stimulation, and flow cytometry staining, as well as practical considerations for assay selection, experimental controls, optimization, and data acquisition.
