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
One distinctive effect on T-cell development was analyzed by selectively increasing serum prolactin (PRL) concentration in thymus-grafted congenitally athymic nude mice and by neutralizing PRL in suspension cultures of thymus from 1-day-old neonatal mice. Flow cytometric analysis of single-positive CD4+ and CD8+ cells derived from inguinal lymph nodes revealed a CD4/CD8 cell ratio of 2.2 +/- 0.18 (mean +/- SEM) in thymus-grafted nude mice that is similar to the ratio for immune-competent BALB/c mice (2.0 +/- 0.06). Addition of the pituitary to thymus-grafted nude mice significantly elevated serum PRL (P < 0.005) and increased the CD4/CD8 cell ratio (2.8 +/- 0.12; P < 0.005), demonstrating preferential stimulation of CD4+ cell development. T cells in nude mice receiving sham (submandibular salivary gland) or pituitary grafts alone were below detectable levels. Suspension cultures of neonatal thymus treated with anti-mouse PRL antiserum resulted in 20% and 30% decreases in double-positive CD4+8+ thymocytes and thymocyte viability, respectively. A 10-fold increase in double-negative CD4-8- thymocytes expressing the interleukin 2 receptor alpha chain, CD25, was also observed concurrently. Our findings illustrate an important way in which PRL may participate in two interrelated mechanisms: the regulation of peripheral single-positive cells and the maintenance of thymocyte viability during the double-positive stage of intrathymic differentiation.
