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

backgroundEarly detection of colorectal cancer (CRC) is important to achieve better survival. Discriminating symptoms suggestive of CRC from benign conditions is a challenge for GPs because most known 'alarm symptoms' have low predictive values.

aimTo further understand the diagnostic process of CRC in general practice in terms of healthcare use and by analysing factors related to diagnostic intervals. DESIGN AND

settingA multimethod approach comprising a historical, prospective registry study and qualitative content analysis.

methodHealthcare use in the year before referral for colonoscopy was compared between patients diagnosed with CRC and an age-, sex,- and GP-matched control population. Qualitative content analysis was performed on free texts in electronic patient records from a purposive sample of patients with CRC.

resultsPatients with CRC (

conclusionFewer missed diagnostic opportunities might occur if GPs are aware of pitfalls in diagnosing CRC: the assumption that symptoms are caused by comorbid conditions or medication, or relating complaints to pre-existing medical conditions. GPs also need to be aware that repeated digestive complaints warrant rethinking an earlier diagnosis.
