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.
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
BACKGROUND AND
objectiveThe actual evaluation of immunological function is significant for studing the tumor development and devising a treatment in time. The aim of this study is to evaluate the immunological function of advanced lung cancer patients systematically, and to discuss the clinical significance.
methodsThe nucleated cell amounts of advanced lung cancer patients and the healthy individuals were counted. The immune cell subsets and the levels of IL-4, INF-gamma, perforin and granzyme in CD8+T cells by the flow cytometry were measured. The proliferation activity and the inhibition ratio of immune cells to several tumor cell lines were evaluated by MTT assay.
resultsThe absolute amounts and subsets of T, B, NK cells of advanced lung cancer patients were lower than the healthy individuals (P < 0.05); However, the proportion of regulatory T cells of advanced lung cancer patients (4.00 +/- 1.84)% was lower than the healthy individuals (1.27 +/- 0.78)% (P < 0.05). The positive rates of IFN-gamma perforin, granzyme in CD8+T cells decreased while them in IL-4 did not in the advanced lung cancer patients compared to the healthy control group (P < 0.05). The proliferation activity of immune cells, the positive rate of PPD masculine and the inhibition ratio to tumor cells in the advanced lung cancer patients was lower than the healthy subsets obviously (P < 0.05).
conclusionThere was a significant immune depression in the advanced lung cancer patients compared to the healthy individuals.
