Postnatal development of lung T lymphocytes in a porcine model.
Article in Lung, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
purposeDespite the high prevalence of respiratory diseases in the world and the extensive information available on the mucosal immune system, research on the development of the lung immune system in humans is limited by technical and ethical considerations; therefore, we studied the postnatal development of T lymphocytes in lung lobes in a porcine model.
methodsUsing less than 36-hour-old (NB), 1-week-weaned (5-week-old -AW-), 3-month-old (3M), and 4-year-old (4YR) healthy, nonvaccinated, specific pathogen free (SPF) Vietnamese miniature pigs, we studied the CD3+, CD4+, CD8+, TCR1 (gamma-delta T cells), and CD25+ (IL-2R-alpha) cell subpopulations in lung lobes parenchyma, bronchoalveolar lavage (BAL), peripheral blood mononuclear cells (PBMC), and cervical lymph nodes (LN) by flow cytometry.
resultsNo differences among lung lobes were detected in any of the cell subpopulations tested. A low proportion of T cell subsets was detected in NB and 4YR groups in lung and BAL. Besides, the AW and 3M groups showed important changes in T cell subpopulations.
conclusionsThese results suggest that in healthy animals the lung lobes behave as a homogeneous immune organ. T cells were detected in very low percentages at birth and in adult life, which may explain the high susceptibility to respiratory infections both early and later in life. Postweaning antigenic challenges and endocrine and sexual maturity at 3M had important effects on the development of the mucosal immune system. It was also evident that changes at mucosal sites were poorly correlated with PBMC and LN.
