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

We aimed to investigate the differences in prognosis between patients with HER2-low and HER2-zero status. This retrospective cohort study conducted at multi-institution included 1627 patients diagnosed with HER2-low or HER2-zero breast cancer (stages I-III). Survival analysis after propensity score matching was used. In total, 445 patients with HER2-low and 707 patients with HER2-zero status were included. The median follow-up was 92.7 months. Locoregional and distant recurrence-free survival were comparable between patients with HER2-low and HER2-zero status (p = 0.872, p = 0.746, respectively). HER2-low status did not affect overall survival. However, in subgroups with lymph node metastases, patients with HER2-low status showed better recurrence-free survival compared with that of patients with HER2-zero status (p = 0.033). In conclusion, survival outcomes were comparable between patients with HER2-low and HER2-zero breast cancer. More studies are needed to validate our findings and examine the biological mechanism underlying these prognostic differences.
