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 is a generally safe agent prescribed in the systemic treatment of breast cancer. Tinnitus is not a currently known adverse event related to trastuzumab. Here, we describe a rare case of severe tinnitus and a migraine headache induced by trastuzumab used for adjuvant therapy. CASE SUMMARY: A 37-year-old woman was diagnosed with hormone receptor-positive and human epidermal growth factor receptor 2-positive breast cancer. After surgery, she was treated with four cycles of epirubicin and cyclophosphamide; she then received docetaxel and a loading dose of trastuzumab plus pertuzumab. Less than half an hour after trastuzumab infusion, the patient complained of severe tinnitus and left-sided migraine headache. Trastuzumab monotherapy was discontinued immediately, and symptoms disappeared after 10 min. Trastuzumab was readministered, and severe tinnitus and migraine headache recurred. Trastuzumab was stopped, and severe tinnitus diminished after 10 min. Pertuzumab and docetaxel therapy was then administered, and no adverse events were observed. Subsequent infusions of trastuzumab every three weeks did not show the same symptoms.
conclusionAlthough trastuzumab is well-tolerated in most patients, we should pay attention to the risk of severe tinnitus and migraine.
