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
purposeThe impact of cancer-related diarrhea (CRD) on changes in cancer therapy remains poorly characterized despite its prevalence.
methodsWe performed a longitudinal observational study using IQVIA PharMetrics Plus claims data. Patients included adults with CRD identified by diagnosis codes or pharmacy claims and compared their outcomes to matched (1:1) patients without CRD. Treatment parameters (discontinuation, persistence, augmentation, dose titration, adherence) were evaluated and stratified for the first cancer therapy (chemotherapy vs. targeted therapy vs. both). A multivariate Cox proportional hazards model was used to estimate the difference in risk of each treatment parameter between cohorts, adjusting for cancer type, therapy, and comorbidities.
resultsWe identified 104,135 matched pairs of patients with solid (n = 94,411) or hematologic cancers (n = 9,724) receiving chemotherapy (n = 47,220), targeted therapy (n = 2,427), or both (n = 5,313). Patients with CRD discontinued therapy more frequently than those without CRD (chemotherapy [81.5% vs. 62.3%], targeted therapy [69.2% vs. 64.3%], both [96.0% vs. 85.5%], p < 0.0001). The overall proportion of discontinuation was higher (82.4% vs. 64.6%, p < 0.0001), including a higher risk of discontinuation (HR = 1.40, p < 0.001) for patients with CRD. The mean time to discontinuation (59.6 ± 54.1 vs. 68.3 ± 76.6 days), switch (72.0 ± 48.6 vs. 96.9 ± 84.0 days), persistence (95.1 ± 98.1 vs. 154.3 ± 142.7 days), and adherence (25.5% ± 37.2 vs. 47.9 ± 41%) were all lower (p < 0.0001) among patients with CRD.
conclusionPatients who develop CRD undergo significant and clinically impactful index treatment discontinuation, treatment switching, and have lower adherence and persistence of anticancer therapy compared to patients without CRD. Strategies to control CRD to optimize cancer therapy are urgently needed.
