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

objectivesThe tumor suppressor gene entitled programmed cell death 4 (PDCD4) encodes a protein that inhibits neoplastic transformation and invasion. The aim of this study was to investigate the expression of PDCD4 and its prognostic roles in human renal cell carcinoma (RCC). MATERIALS AND

methodsA total of 32 paired fresh tumor specimens and adjacent non-cancerous renal tissue from RCC patients by western blot to detect the difference of PDCD4 expression in tumor tissues and non-cancerous tissues. 66 RCC paraffin-embedded specimens and 18 normal renal tissues were analyzed by immunohistochemistry to investigate the association of PDCD4 expression with RCC clinicopathological features.

resultsPDCD4 expression was significantly decreased in RCC compared with normal renal tissues (P = 0.03), and it was found to be significantly associated with RCC metastasis (P = 0.007), tumor T-stage (P = 0.022) and tumor grade (P = 0.015). The mean overall survival was significantly decreased in the low PDCD4 group compared to the high PDCD4 group (low PDCD4: mean overall survival 41.9 months, high PDCD4: mean overall survival 52.9 months, P = 0.008).

conclusionPDCD4 expression strongly correlated to RCC stage, tumor grade, tumor metastasis and tumor-related death. PDCD4 expression was also appears to be a marker in RCC prognosis.
