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

Type 1 Diabetes (T1D) is characterized by the destruction of insulin-producing β cells, leading to hyperglycemia. New therapeutic strategies are crucial for preventing or managing the disease and its complications. Natural or recombinant probiotics, by modulating the gut microbiota and dictating the immunological tolerance, have been recently employed as tolerogenic immunotherapy for autoimmune diseases. Heat shock protein 65 (HSP65) exhibits regulatory and anti-inflammatory activity in autoimmune and chronic inflammatory conditions. Here, we show that dendritic cells from T1D patients exhibit reduced expression of immunological tolerance-associated genes and diminished TLR2 expression. Recombinant HSP65 (rHSP65) upregulated Tlr2 expression and promoted the differentiation of classical dendritic cell subsets-cDC1 and cDC2-capable of inducing regulatory T cells (Tregs) in vitro. Mice administered L. lactis-HSP65 became resistant to T1D, proved by reduced hyperglycemia and lower disease incidence compared to diabetic group that did not receive probiotic. These mice exhibited increased TLR2
