National Variation in Implementation of Sentinel Lymph Node Biopsy for Clinically Node-Positive Patients Undergoing Neoadjuvant Therapy.

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
backgroundSentinel lymph node biopsy (SLNB) is feasible in women with clinically node-positive breast cancer following neoadjuvant chemotherapy and a nodal pathologic complete response. Acceptable false negative rates are achieved through technical considerations such as removing three or more sentinel lymph nodes (SLNs); however, the variation that exists in adherence to this technique is unclear.
objectiveThis study aimed to evaluate recent trends in axillary surgery in women with cN1-cN2 disease who received neoadjuvant chemotherapy, adherence to removing three or more SLNs, and variation in SLN yield.
methodsWe performed a cohort study using the National Cancer Database of women aged ≥18 years with cN1-cN2 disease who received neoadjuvant chemotherapy, including those without a pathologic complete response, from 2012 to 2020. Trends in axillary surgery and lymph node yield obtained during SLNB were evaluated.
resultsThe cohort included 67,365 women (median age 54 years). The number of patients receiving SLNB alone increased from 14 to 39%; SLNB with completion axillary lymph node dissection (ALND) increased from 17 to 30%; and ALND alone decreased from 69 to 27%. The rates of obtaining three or more SLNs during SLNB remained the same over time at 66%, while facility-level variation in obtaining three or more nodes ranged from 40 to 86%.
conclusionsThere has been de-escalation of axillary surgery with fewer patients undergoing ALND; however, overall there has been no significant change in the rates of obtaining three or more lymph nodes during SLNB following neoadjuvant chemotherapy, with significant facility-level variation observed.
