Clinicopathological Factors and Interleukin-6 Levels Associated With Low Relative Dose Intensity in Women With Breast Cancer Receiving First-Line Chemotherapy.
Article in World journal of oncology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Background: Chemotherapy has a substantial role in decreasing the risk of recurrence and mortality in breast cancer (BC) in a dose-dependent manner where a low relative dose intensity (RDI) is associated with unfavorable outcomes. Several baseline clinicopathological factors, including pro-inflammatory biomarkers, were found to be significant determinants of low RDI. This study aimed to explore the occurrence of low RDI and its influencing factors in women with BC. Methods: This cross-sectional study recruited 172 women with stage I-IV BC who received first-line chemotherapy. We collected patients' clinical, pathological, and treatment data and analyzed the pre-chemotherapy C-reactive protein (CRP) and interleukin (IL)-6 levels using a quantitative enzyme-linked immunosorbent assay (ELISA). We calculated the RDI based on the actual and planned delivered chemotherapy dose (mg/m Results: The mean CRP level was 10.82 ± 19.17 mg/L (0.00 - 151.73 mg/L) and the mean IL-6 level was 1.12 ± 3.41 pg/mL (0.00 - 27.67 pg/mL). The average RDI for all patients was 93±8.19%. An RDI < 85% occurred in 23 patients (13.4%). The presence of diabetes mellitus (odds ratio (OR): 4.78, 95% confidence interval (CI): 1.03 - 22.27, P = 0.046), triple-negative tumors (OR: 6.45, 95% CI: 1.39 - 29.83, P = 0.017), and IL-6 levels > 0.5 pg/mL (OR: 3.45, 95% CI: 1.01 - 11.79, P = 0.049) was associated with an increased low RDI risk. Conclusion: The proportion of BC patients receiving a low chemotherapy RDI in our study was comparable to published literature and drove close monitoring of patients at risk to provide adequate management.
