Change in carbohydrate antigen 19-9 level as a prognostic marker of overall survival in locally advanced pancreatic cancer treated with concurrent chemoradiotherapy.
Trial report in International journal of clinical oncology, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled 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.
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
purposeTo investigate the significance of carbohydrate antigen 19-9 (CA19-9) levels for survival in locally advanced pancreatic cancer (LAPC) treated with concurrent chemoradiotherapy (CCRT). METHODS/PATIENTS: We retrospectively reviewed data from 97 LAPC patients treated with CCRT between 2000 and 2013. CA19-9 levels (initial and post-CCRT) and their changes [{(post-CCRT CA19-9 level - initial CA19-9 level)/(initial CA19-9 level)} × 100] were analyzed for overall survival. A cut-off point of 37 U/mL was used to analyze initial and post-CCRT CA19-9 levels. In order to define an optimal cut-off point for change in CA19-9 level, the maxstat package of R was applied.
resultsMedian overall survival was 14.7 months (95% CI 13.4-16.0), and the 2-year survival rate was 16.5%. The estimated optimal cut-off point of CA19-9 level change was 94.4%. On univariate analyses, CA19-9 level change between initial and post-CCRT was significantly correlated with overall survival (median survival time 9.7 vs 16.3 months, p < 0.001). Multivariate analyses confirmed that CA19-9 level change from initial to post-CCRT was the only prognostic factor (p < 0.001).
conclusionsChange in CA19-9 level between initial and post-CCRT was a significant prognostic marker for overall survival in LAPC treated with CCRT. A CA19-9 level increase >94.4% might serve as a surrogate marker for poor survival in patients with LAPC undergoing CCRT, and the prognostic power surpassed other CA19-9 variables including initial and post-CCRT values.
