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

Parathyroid hormone-related protein (PTHrP) has been known to play an important role in the formation of meta-static lesions in the bone. However, there remains controversy over its practical role in predicting the occurrence of bone metastasis and the prognosis of breast cancer patients. In this study, we attempted to investigate the clinical value of PTHrP expression status in the primary lesions of breast cancer patients. We immunohistochemically investigated PTHrP expression in surgically resected specimens from 125 primary breast cancer patients whose clinicopathological background and long-term prognosis were available. Positive PTHrP staining was demonstrated in 79 (63.2%) tumors. PTHrP was expressed significantly more frequently in the tumors of premenopausal patients. Bone metastases were significantly more common in patients with T4 tumors, with a positive node, with distant metastasis and with PTHrP-positive tumors. Multivariate logistic analysis revealed positive PTHrP expression as an independent risk factor for predicting bone metastasis. PTHrP expression was significantly related to a shorter overall survival. Bone metastasis was found significantly more frequently (28.3%) in PTHrP- and node-positive cases than in double-negative cases, and the rate was more pronounced in postmenopausal cases (32.1%). Expression of PTHrP in primary lesions, in combination with positive nodal status, is indicative of an increased risk of bone metastasis in breast cancer patients.
