Neoadjuvant chemotherapy impacts axillary lymph node positivity in early breast cancer (cT1-2N0M0) with negative axillary lymph nodes at diagnosis.

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
Purpose: This study compared the role of neoadjuvant chemotherapy (NAC) followed by surgery vs. upfront surgery for avoiding axillary lymph node dissection (ALND) in patients with cT1-2N0M0 breast cancer and clinically negative axillary lymph nodes (LNs) at diagnosis. Patients and methods: Medical records of a sample of 1,695 patients with a primary diagnosis of axillary LN-negative early-stage breast cancer who underwent surgical treatment for breast cancer at the First Bethune Hospital of Jilin University between June 2019 and December 2022 were retrospectively reviewed. The positive rate of sentinel lymph nodes (PR Results: 15 patients who received NAC followed by surgery and 79 patients who underwent upfront surgery had positive SLNs. Four patients who received NAC followed by surgery and 1 patient who underwent upfront surgery had other positive LNs. Overall, NAC followed by surgery significantly lowered PR Conclusion: NAC may reduce the rate of axillary LN positivity and the likelihood of ALND in patients aged 40-60 years with cT2N0M0 HER2+ breast cancer and clinically negative axillary LNs at diagnosis.
