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

backgroundColorectal cancer (CRC) in "young" patients under 50 years of age is uncommon. There have been conflicting reports regarding both the clinicopathological features of CRC in young patients and prognosis. The aim of this study was to review and compare the clinical characteristics, prognostic factors, and overall survival of patients in three different age groups (40 years and under, 41-50 years, over 50 years of age) and the prognosis of these patients.

methodsA total of 2,426 consecutive patients who had undergone surgical resection for sporadic colorectal cancer at Singapore General Hospital in the period from 2000 to 2005 were retrieved from a prospectively collected computer database. There were 73 patients (3.0 %) in Group 1 (40 years old or less), 257 (10.6 %) in Group 2 (41-50 years old), and 2,096 (86.4 %) in Group 3 (>50 years old). Clinicopathological features were assessed using univariate analysis to evaluate significant differences, survival curves were constructed using the Kaplan-Meier method, and multivariate analysis was performed to evaluate the independent prognostic factors.

resultsYoung CRC patients tend to present with a higher incidence of mucinous and signet ring cell tumors (Group 1-20.5 %, Group 2-8.2 %, Group 3-6.2 %, p < 0.001) and have more poorly differentiated tumors (Group 1-20.0 %, Group 2-9.7 %, Group 3-7.4 %, p = 0.014). Furthermore, young CRC patients tend to present with regional lymph node metastases (Group 1-65.7 %, Group 2-60.8 %, Group 3-51.0 %, p = 0.001) and distant metastases (Group 1-31.5 %, Group 2-24.1 %, Group 3-19.4 %, p = 0.006). Multivariate analysis reveals, however, that young age is not an independent prognostic factor for cancer-specific survival (CSS) (p = 0.392). Five-year CSS for Group 1 was 56.6 % (95 % confidence interval (CI) 44.8-68.4 %), Group 2 53.8 % (95 % CI 47.3-60.3 %), and Group 3 61.1 % (95 % CI 58.9-63.3 %).

conclusionsAlthough presenting with advanced tumors and with poorer prognostic factors such as presence of mucin and poor histological differentiation, young CRC patients do not have a worse prognosis.
