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

aimsTo improve the diagnostic value of fine needle aspiration biopsy of pancreatic lesions using a simple mutation detection method based on the polymerase chain reaction (PCR).

methodsFine needle aspirates from 21 suspected pancreatic lesions were analysed for K-ras codon 12 point mutations using solid phase minisequencing.

resultsA point mutation in codon 12 of the K-ras gene was detected in 14 of 17 cases of pancreatic carcinoma. No false positive results were recorded. The concordance of the result with routine cytology was 78%. All patients diagnosed as having malignant disease on cytology also had a K-ras point mutation. Additional information on the presence of malignancy was obtained using molecular genetic analysis in two cases.

conclusionsPCR based minisequencing is a promising method for the analysis of cytological material. K-ras point mutation analysis was modified to enable it to be carried out in a clinical laboratory. Advantages of the method include its simplicity and speed. Adequate sampling guidance is important but analysis can be performed even with small amounts of cellular material.
