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) is a major global health concern, with a rising incidence in young individuals. Early-onset CRC displays unique clinicopathological and molecular characteristics, necessitating a closer examination of prognosis, particularly in the context of adjuvant chemotherapy. This study aimed to investigate the prognosis of early-onset CRC patients (< 50 years) diagnosed at stage II/III compared to older counterparts, utilizing propensity score matching to minimize heterogeneity.

methodsA retrospective analysis of 3324 stage II/III CRC patients aged < 70 years was conducted, focusing on age-based subgroups (< 50 vs. ≥ 50 years). Propensity score matching balanced clinical characteristics. Relapse-free survival (RFS) and overall survival (OS) were analyzed.

resultsIn stage II CRC, age of onset did not impact prognosis after adjuvant chemotherapy, with no significant differences in RFS (5-year RFS rates: 80% in both groups, p = 0.98) and OS (5-year OS rates: 96% vs. 92%, p = 0.17). In stage III, a trend suggested slightly poorer OS in patients aged < 50 years than those ≥ 50 years (5-year OS rates: 85% vs. 88%, p = 0.077). However, in a propensity score-matched cohort, age-dependent differences were attenuated (5-year OS rates: 85% vs. 88%, p = 0.32).

conclusionIn the context of stage II/III CRC patients receiving adjuvant chemotherapy, age was not an independent predictor of prognosis. Age alone should not be the sole factor guiding treatment decisions.
