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

Natural killer T (NKT) cells are a subset of innate immune cells displaying a limited repertoire of antigen specificities and CD1d restriction. Little is known about contribution of NKT cells in cancer initiation and progression. In this study, the frequencies of NKT-like cells, B cells expressing CD1d molecule and CD4(+) regulatory (Treg) cells were analyzed in 40 patients with chronic lymphocytic leukemia (CLL) and 15 healthy subjects by flow cytometry. Our results showed that the frequency of CD3(+)CD56(+) NKT-like cells is significantly decreased in progressive (4.9 ± 0.8 % of total CD3(+) T cells) compared with indolent (8.1 ± 1.2 %, p = 0.036) patients and healthy subjects (10.6 ± 1.7 %, p = 0.003). However, no association was found between NKT-like cell frequency and immunoglobulin heavy chain variable region gene (IGHV) mutation or CD38 and ZAP70 expression. On the other hand, expression of CD1d molecule was significantly higher in leukemic B cells of patients with CLL (75 ± 1.5 % of total CD19(+) B cells) compared to B cells from healthy subjects (59.6 ± 2.2 %, p < 0.001), with no significant difference between progressive and indolent patients. Interestingly, the frequency of Treg cells was inversely correlated with that of NKT-like cells in patients with CLL (r = -0.4, p = 0.002). Our results suggest a protective role for NKT-like cells in patients with CLL, which seems to be downregulated presumably by Treg cells.
