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

backgroundNeoadjuvant chemotherapy (NAC) may allow de-escalation of axillary surgery; yet treatment disparities persist. We aimed to assess race-based disparities in use of axillary lymph node surgery (ALND) among patients who achieve a nodal response in the context of a large, multicenter NAC trial.

methodsWe conducted a retrospective analysis of the I-SPY 2 trial. All patients received NAC, but type of surgery was not mandated. Multivariable logistic regression was used to predict odds ratio (OR) of undergoing ALND by race while adjusting for clinical and demographic confounders, including age, region, tumor receptor subtype, clinical and pathologic node status (cN and ypN +/-, respectively), and clinical and pathologic tumor size (cT and ypT, respectively).

resultsAmong 1394 patients, 79.4% identified as White, 11.2% Black, and 9.4% Asian/other. More than half (52.5%) were cN+ at baseline, and 66.9% were ypN- after NAC, with no significant differences in nodal downstaging by race. Overall ALND rates were higher in Black patients (50.6%) compared to White (37.5%) and Asian/other (38.9%) patients (p = 0.007). Notably, among those who converted from cN+ to ypN-, Black patients underwent ALND more frequently (62%) than White (41.2%) and Asian/other (40%) patients (p = 0.021). In multivariable analysis, Black patients had 70% higher odds of undergoing ALND compared with White patients (OR 1.7, 95% confidence interval (CI) 1.09-2.66, p = 0.02).

conclusionsDespite no differences in nodal downstaging, Black patients in I-SPY 2 were significantly more likely to undergo ALND. These disparities may stem from unmeasured patient, provider, or systemic factors affecting surgical planning.
