1 · What the graph read from 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.

2 · The registry

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

Intrinsic antioxidant enzymes (AE) are essential for protection against potential cellular damage by free radicals (FRs), which affect a variety of biological processes. The levels or activities of AEs can be abnormal in human malignancies in general, and FR production is a possible mechanism of estrogen related carcinogenesis specifically. However, the role of AEs in breast cancer ramains unclear. Immunodetectable AEs were characterized in 95 node negative cancers using rabbit polyclonal antibodies. Results were correlated with established and experimental biomarkers of breast cancer. AEs were greater than benign differentiated epithelium in more than 40% and lower in 10-14% of tumors. Patterns of staining were enzyme and tumor pattern specific. Increased immunodetectable AE was associated with large, poorly differentiated tumors, and younger age. Catalase correlated with nuclear grade and disease related death (p< 0.05), and highlighted tumor microvasculature. Additional work in this area may further elucidate the role of AEs in breast cancer growth and progression.
