Proton pump inhibitor concomitant use to prevent oxaliplatin-induced peripheral neuropathy: Clinical retrospective cohort study.
Article in Pharmacotherapy, 2025. 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
backgroundOxaliplatin-induced peripheral neuropathy (OIPN) is a major clinical challenge because it leads to discontinuation of chemotherapy. Omeprazole, a proton pump inhibitor (PPI), has been shown to prevent OIPN in a rat model. Therefore, we aimed to test whether the concomitant use of a PPI reduces oxaliplatin discontinuation due to OIPN.
methodsThis retrospective study used data from 1015 patients who started treatment with oxaliplatin and evaluated two cohorts (PPI vs. non-PPI). The primary outcome measure was oxaliplatin discontinuation due to OIPN. A Kaplan-Meier curve was generated for cumulative doses and evaluated using the log-rank test and Cox proportional hazards analysis.
resultsThe log-rank test showed that the number of patients who discontinued oxaliplatin due to OIPN was significantly lower in the PPI group (p = 0.0264). Cox proportional hazards analysis incorporated and analyzed factors previously reported as potentially affecting neuropathy (sex, age, use of PPIs, calcium channel antagonists, opioids and adjuvant analgesics, and the CAPOX [capecitabine + oxaliplatin] regimen). The analysis suggested that the concomitant use of PPIs was a factor in reducing oxaliplatin discontinuation (adjusted hazard ratio [HR] = 0.568, 95% confidence interval [CI], 0.344-0.937, p = 0.0269). Since there were significant differences in some patient demographics between the two groups, propensity score matching was performed to align the patient demographics and then reanalyzed. After propensity score matching, the same analysis as above showed that oxaliplatin discontinuation due to OIPN was significantly less common in the PPI group (p = 0.0081); cox proportional hazards analysis showed that PPI use was a factor that significantly reduced oxaliplatin discontinuation due to OIPN (adjusted HR = 0.478, 95% CI, 0.273-0.836, p = 0.0096).
conclusionsThese results suggest that concomitant PPI use may reduce oxaliplatin discontinuation due to OIPN in patients receiving oxaliplatin.
