C-Reactive Protein-to-Albumin Ratio as a Predictive Indicator for Evaluating Tolerability in S-1 Adjuvant Chemotherapy after Curative Surgery for Pancreatic Cancer: An External Validation Cohort Study.
Article in Cancers, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundS-1 in adjuvant chemotherapy (AC) administration after pancreatic cancer (PC) surgery has been standardized in Japan. The Ehime study confirmed that a postoperative higher C-reactive protein-to-albumin ratio (CAR) value predicted the risk of adverse event (AE)-related S-1 non-completion as an AC in patients with PC after curative surgery. This study aimed to investigate the index to predict S-1 tolerance among patients who underwent curative surgery for PC (the Dokkyo study).
methodsThis retrospective validation cohort study included 172 patients at the Department of Hepato-Biliary Pancreatic Surgery, Dokkyo Medical University, Japan, from January 2010 to December 2022. All patients underwent nutritional screening using the postoperative CAR. S-1 completion status and its effect on prognosis were systematically followed up and investigated. We conducted a statistical analysis of predictive markers to investigate their association with S-1 completion.
resultsPatients were categorized into the S-1 completion (N = 91) and non-completion (N = 81) groups. The S-1 completion group demonstrated a significantly lower CAR than the S1 non-completion group. Moreover, the current study revealed a significant difference in the S-1 completion rate, applying the CAR cutoff value of 0.05 established in the Ehime study. Additionally, univariate and multivariate analyses confirmed that a CAR of <0.05 was significantly associated with S-1 completion.
conclusionsThe Dokkyo study confirmed the results observed in the Ehime study. Consequently, an increased postoperative CAR value appeared as a universal applicable marker for the risk factor of AE-related S-1 non-completion after curative surgery for patients with PC.
