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

Pancreatic cancer (PC), a malignancy with very poor prognosis, presents many molecular alterations, including overexpression of Cyclin B1. However, the prognostic value of the protein in PC remains to be elucidated. In the present study, Cyclin B1 expression was detected immunohistochemically in specimens from 241 patients with PC and was correlated with clinicopathological features and patient survival. It was found that Cyclin B1 expression, located in nucleus and/or cytoplasm, was not statistically associated with clinicopathologic variables. However, overall survival of patients with high Cyclin B1 expression was significantly poorer than that of those with low Cyclin B1 expression (P = 0.010). Moreover, Cyclin B1 was identified as an independent prognostic factor by multivariate Cox regression test (P = 0.003). Finally, its independent implication for prognosis was proven in five subgroups of PC, i.e., males, patients aged ≤ 65 years, G1-2 and N0 tumors as well as those with perineural invasion (all P < 0.05). These data indicate that high expression of Cyclin B1 is a valuable molecular marker of unfavorable prognosis in PC.
