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

Diarrhoeal diseases are the second leading cause of death in children worldwide. Epidemiological studies show that co-infection with the protozoan parasite Giardia intestinalis decreases diarrhoeal severity. Here we show a high incidence of asymptomatic Giardia infection in school-aged children from Nigeria. In a mouse model, Giardia induced a Type 2 mucosal immune response, characterized by antigen-specific Th2 cells, IL-25, Type 2 cytokines, and goblet cell hyperplasia. Single-cell RNA sequencing and multiparameter flow cytometry revealed expansion of IL-10-producing Th2 cells, which promoted parasite persistence and protected against Toxoplasma gondii-induced ileitis and dextran sulfate sodium-induced colitis. This protective effect was STAT6 dependent, as IL-4R blockade or STAT6 deficiency impaired IL-10
