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

purposeMultidisciplinary tumor boards (MTBs) intend to increase the quality of cancer care. Research on the association of adherence to MTB recommendations with survival is limited. This study aims to determine the impact of adherence to MTB recommendations on survival in colorectal cancer patients.

methodsThis is a retrospective, observational study including patients diagnosed between 01.01.2014 and 31.12.2018. Electronic health records were reviewed to determine the adherence. Study endpoints were adherence rate, disease-free survival (DFS), and overall survival (OS). Follow-up was performed until 12.12.2023.

resultsThere was a significant difference in DFS (median DFS: 79 months [95% CI, 73-89] vs 22 months [95% CI, 17-87]) and OS (median OS: 78 months [95% CI, 75-86] vs 65 months [95% CI, 28-NR]) between the adherent group (n=406) versus the non-adherent group (n=52) (log-rank test, p<0.05). Performance status, stage and non-adherence were independent predictors of survival in the multivariate analysis (p<0.05 for all). The most common reason for non-adherence was patient preference (n=23).

conclusionWhile MTBs have become an indispensable part of clinical practice, adherence to MTB recommendations was crucial to achieve survival benefit in this study. Patient preference should be prospectively analyzed from a patient and caregiver perspective in future studies.
