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
backgroundTreatment of breast cancer by chemotherapy or radiotherapy exposes the patient to the risk of cardiotoxicity, which can be assessed pre-therapeutically using scores such as the Heart Failure Association and International Cardio-Oncology Society (HFA-ICOS) score. We aimed to evaluate the risk of cardiotoxicity using the HFA-ICOS score in a group of Cameroonian women before treatment of breast cancer by chemotherapy and/or radiotherapy.
methodsWe conducted a cross-sectional analytic study using retrospective data collected from the Cardiology and Oncology departments at Yaounde Central Hospital and the Internal Medicine department at Yaounde General Hospital over an eight-year period, from 2017 to 2024, with a focus on the nine months from November 2023 to June 2024. Inclusion criteria consisted of patients with histologically confirmed breast cancer treated with chemotherapy and/or radiotherapy. We performed a multivariate analysis to determine the factors associated with moderate and high risk of cardiotoxicity, with a significance threshold of p ≤ 0.05.
resultsOf the 130 patients recruited, the median age was 46.5 years (interquartile range, IQR, 36.75-58.00), with extremes of 21 and 76 years. Comorbidities mainly were overweight/obesity in 92 (70.7%) cases and arterial hypertension in 32 (24.6%) cases. Invasive ductal carcinoma was the main histological type, accounting for 126 (96.9%) cases, and triple-negative carcinoma was the most frequent molecular subtype, comprising 55 (42.3%) cases. Treatment consisted of exclusive chemotherapy in 96 (73.8%) cases and radiotherapy associated with chemotherapy in 27 (20.8%) cases. Based on the HFA-ICOS score, the cardiotoxicity risk was low in 93 (71.5%) patients. The independent factors associated with the risk of moderate to severe cardiotoxicity were age ≥ 60 years (adjusted OR: 5.97; 95% CI 1.73-20.60; adjusted p = 0.005), obesity (adjusted OR: 5.81; 95% CI 1.78-18.91; p = 0.003) and hypertension (adjusted OR: 27.10; 95% CI 7.51-97.76; p < 0.001). Exclusive chemotherapy was a protective factor (adjusted OR: 0.24; 95% CI 0.07-0.81; adjusted p = 0.021).
conclusionWomen with breast cancer in Cameroon tend to be relatively young and present a low risk of cardiotoxicity before starting anti-cancer treatment.
