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
backgroundFor the management of acute coronary syndrome, literature shows lower healthcare providers' guideline adherence for women than for men. Since less is known about the management of chronic coronary syndrome (CCS), this study investigated patient-related sex differences in providers' guideline adherence for invasive coronary angiography (CA) performed in patients with suspected CCS.
methodsUsing data from the German ENLIGHT-KHK trial, patients with suspected CCS who underwent a CA were analysed. To assess the association between patient sex and physicians' adherence to the German National Disease Management Guideline "Chronic coronary artery disease" of 2019, binary logistic regression models were developed. Covariates included age, symptoms, risk factors, comorbidities, and non-invasive testing and its results. To examine sex differences in predictors of guideline adherence, models were run separately for women and men.
resultsTwo hundred seventy-three women and three hundred eighty-six men were included (aged 67 ± 10 years). Physicians' guideline adherence for CA was lower for women than for men (19.4% vs. 30.1%, p = 0.002). CAs were less likely to be guideline-adherent for women with suspected CCS than men (OR 0.4, p < 0.05). Guideline adherence predictors differed between women and men. For example, men's predictors included non-invasive testing and its results, age, typical angina and smoking; of these, only a positive non-invasive test result had an impact for women.
conclusionOur results indicate a less guideline-adherent diagnostic workup of CA for women with suspected CCS than men. This might reflect a limited awareness of CCS in women and insufficiently sex-specific guideline recommendations.
