1 · What the graph read from it

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.

2 · The registry

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

Male breast cancer (MBC) is a rare condition, accounting for < 1% of all breast cancer cases. Reports of bilateral synchronous MBC are even more uncommon. Although lobular carcinoma is generally absent in the male mammary gland, a few cases of lobular carcinoma in MBC have been documented, comprising 1%-2% of all MBC cases. A man in his 80s presented to our hospital with a mass on his left nipple. After detailed examination, he was diagnosed with invasive ductal carcinoma of the left breast and invasive lobular carcinoma of the right breast. Because he had a family history of breast cancer, he underwent genetic testing and was found to have a
