Peripheral blood lymphocyte subpopulations in schoolchildren born very preterm.
Article in Archives of disease in childhood. Fetal and neonatal edition, 1999. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
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
aimTo investigate whether lymphocytes or serum inflammatory markers are associated with obstructive lung disease and bronchial lability in schoolchildren born very preterm.
methodLymphocyte subsets were studied in the peripheral venous blood of 29 such children (median age 8.8 years). Serum eosinophil cationic protein (ECP) and myeloperoxidase (MPO) concentrations and the association between them, lymphocyte subsets, and lung function were studied. Fourteen healthy children born at term, median age 9.1 years, served as controls. T lymphocytes (CD3), T lymphocyte subpopulations (CD4 and CD8), B lymphocytes (CD19), natural killer cells (CD16+56) and activation markers of T and B lymphocytes (CD23 and CD25) were determined using flow cytometry. Lung function was measured in all children both in the clinic and at home (Vitalograph Data Storage Spirometer).
resultsCompared with the controls, schoolchildren born very preterm had significantly lower CD4(+) T cell percentages and CD4:CD8 ratios (p < 0.05 for both), whereas natural killer cell percentages and serum ECP values were significantly higher (p < 0. 05). The very preterm schoolchildren had significantly lower spirometric values than the control group (p < 0.05)-except forced vital capacity. When all the subjects were considered together, a weak, but significant, negative association was observed between the bronchial responsiveness in peak expiratory flow, after a beta(2) agonist during home monitoring, and the CD4(+) T cell percentage (r = -0.45; p = 0.008) and the CD4:CD8 ratio (r = -0.50; p = 0.003), indicating a relation between bronchial lability and imbalance of T cell subpopulations.
conclusionsThese results suggest that there is an inflammatory basis for lung function abnormalities in schoolchildren born very preterm.
