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
introductionRibociclib is an orally bioavailable cyclin-dependent kinase 4/6 inhibitor. In combination with aromatase inhibitor letrozole, it has approval for treatment of hormone receptor positive (HR+) and human epidermal growth factor receptor 2-negative (HER2-) advanced breast cancer. First-line therapy with ribociclib + letrozole significantly improves progression-free survival compared to placebo + letrozole in patients with HR+/HER2- advanced breast cancer. In patients with de novo advanced or metastatic breast cancer, ribociclib was able to provide substantial clinical benefit according to data from the MONALEESA-2 study. CASE PRESENTATION: Here, we report the complete clinical response in a postmenopausal patient with de novo, locally advanced, pulmonary metastatic breast cancer treated with ribociclib + letrozole. Our patient presented an ulcerated breast-consuming tumor with multiple pulmonary metastases. HR+/HER2- breast cancer was confirmed by tumor biopsy. Ki67 expression was 90%. After three months of initial treatment, the tumor-associated ulcerations disappeared, and no measurable pulmonary disease was detectable on CT scan. Treatment was well tolerated, and after dosage reduction due to neutropenia, no further side effects have been documented. At present, complete clinical response remains after 15 months of ongoing treatment.
conclusionThis case report documents an exceptional tumor response of a fast growing, locally advanced, pulmonary metastatic HR+/HER2- de novo breast cancer treated by ribociclib/letrozole combination therapy. Treatment success was long lasting with few side effects. The patient was very satisfied with the treatment and had no specific restrictions in her daily life.
