Frequency of and sex differences in cancer treatment-related cardiac dysfunction in trastuzumab-treated patients with salivary gland cancer: a retrospective cohort study.

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
backgroundTrastuzumab treatment for salivary gland, gastric, and breast cancer commonly causes cancer treatment-related cardiac dysfunction (CTRCD). CTRCD incidence by sex has not been well studied.
methodsThis retrospective cohort study investigated frequency of and sex differences in CTRCD in patients with salivary gland cancer treated with trastuzumab at our hospital from April 2017 to March 2022. All patients underwent echocardiography at baseline and after the first, third, and sixth trastuzumab courses. We measured changes in global and regional longitudinal strain (LS) after trastuzumab administration. CTRCD was defined by left ventricular ejection fraction (LVEF) or global LS (GLS). The results were compared by sex.
resultsWe recorded clinical data of 49 patients (median age [IQR], 65 [55-71] years; males [75.5%]). The median follow-up period after the sixth trastuzumab course was 120 (111-128) days. One female patient and no male patient had CTRCD defined by LVEF, and two female patients (16.7%) and seven male patients (18.9%) had CTRCD, defined by GLS. The Kaplan-Meier curves showed no significant difference in CTRCD frequency, defined by GLS (log-rank, p = 0.88), between female and male patients. In the univariate analysis, sex was not associated with CTRCD, defined by GLS. A significant difference in apical LS was observed between baseline and the third follow-up results of male patients.
conclusionsIn this study, CTRCD incidence was not significantly different between male and female patients with salivary gland cancer treated with trastuzumab. Although most previous studies have looked at female patients with breast cancer, a male patient may be found to be at similar risk of myocardial damage.
