Revisiting influences on tumor development focusing on laboratory housing.
Article in Journal of the American Association for Laboratory Animal Science : JAALAS, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled 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.
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
Spontaneous tumors are reported to occur in 45% to 71% of Sprague-Dawley rats, yet few studies have considered the effect of the sedentary condition of standard laboratory cages on tumorigenesis. Tumor profiles and tumor promoting hormone prolactin were compared in female Sprague-Dawley rats (108) that were allocated into 3 groups: those housed without outside activity (SED group), with twice-weekly 1-h sessions of physical activity in large box (PA group), and with regular voluntary running-wheel exercise (EX). Compared with the EX group, SED rats had more and larger tumors throughout most of their lifespan; tumor profiles of PA rats were similar to those of the SED group. A larger percentage of animals in the SED group had tumors (54%), compared with EX rats (38%). At 64 wk, tumors in SED animals included thyroid carcinoma, malignancy, mammary fibroadenoma, cystadenoma, and granuloma, whereas benign mammary gland cysts were most common in EX. Prolactin levels were highest in SED animals at 24 and 52 wk. In conclusion, increased tumor number, increased tumor size, type of spontaneous tumor, and increased prolactin in rats were associated with standard laboratory housing, which limited physical activity, and were not primarily due to aging.
