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

Formalin-fixed paraffin-embedded material from 57 patients in whom curative resection of pancreatic carcinoma had been attempted was analysed by an immunohistochemical procedure to estimate proliferation and p53 protein expression. Using the monoclonal antibody (MAb) MIB-1, which recognizes a Ki-67 epitope, the proliferating cell index (PCI, percentage of immunoreactive tumour nuclei) and proliferating cell area (PCA, percentage of immunoreactive tumour nuclear area) were calculated using an interactive image analysis system and were compared with semiquantitative scoring of stainability. MAb DO-7, which recognizes both wild- and mutant-type p53 protein, was used to assess p53 expression in the same material. MIB-1 stainings were of high quality in 53 tumours. The median PCI was 29.7% (range 0.5-82.1%) and the median PCA was 10.6% (range 0.0-36.5%). There was a close correlation between PCI and PCA (P < 0.0001). PCI and PCA values were in conformity with the semiquantitative scoring (P < 0.0001). The p53 immunohistochemical stainings were successful in 48 tumours and the protein was expressed in 22 (46%). High PCI values (> 45%, n = 14) correlated with shorter survival time (P < 0.01). PCA (P < 0.05) and the expression of p53 protein (P < 0.001) were independent prognostic variables.
