Clinical impact of the Z0011 trial on axillary surgical management in Australia and New Zealand from the BreastSurgANZ Quality Audit.

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
backgroundThe clinical management of the axilla in early breast cancer has changed since the Z0011 trial, which showed that axillary lymph node dissection (ALND) is not necessary in select patients with a positive sentinel lymph node biopsy (SLNB). Studies have shown a significant decrease in the rates of completion ALND (cALND) since Z0011. The aims of this study were to investigate the effect of the Z0011 trial on the management of positive axillary sentinel nodes and the trends in axillary surgical management since 2005 in Australia and New Zealand.
methodsThis study utilized prospectively maintained data from the BreastSurgANZ Quality Audit (BQA). Patients with early breast cancer between 2005 and 2023 satisfying the Z0011 trial inclusion criteria undergoing SLNB or SLNB followed by cALND were identified.
resultsThere were 91 196 patients who underwent breast-conserving surgery and SLNB of which 12 035 were node positive therefore satisfying the Z0011 trial inclusion criteria, of which 8194 (68.1%) received SLNB only with no cALND. There has been a 55.4% reduction in the rate of cALND after 2010 when the Z0011 trial was published (P < 0.001). There was a significant downward trend in the number of cALND performed per year (R
conclusionThe Z0011 trial was a practice changing trial and since its publication in 2010 has been correlated with de-escalation in surgical management of the axilla and decline in the rates of cALND in Australia and New Zealand.
