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

introductionNational guidelines specify against immediate breast reconstruction (IBR) among inflammatory breast cancer (IBC) patients. However, limited data exist regarding this practice. We report practice patterns and oncologic outcomes among nonmetastatic IBC patients receiving trimodality therapy, with or without IBR.

methodsUsing the National Cancer Database, we identified nonmetastatic IBC patients treated with trimodality therapy from 2004 to 2016. Primary outcome was overall survival (OS), assessed on unadjusted analysis using Kaplan-Meier estimates and on adjusted analysis using multivariable Cox proportional hazards and inverse probability weighting (IPW) models. OS analysis was also conducted with propensity score matched (PSM) cohorts. Secondary outcomes included IBR utilization rates, time to postmastectomy radiotherapy (PMRT), and surgical outcomes.

results6589 women were included, including 5954 (90.4%) non-reconstructed and 635 (9.6%) IBR. Among IBR recipients, 250 (39.4%) underwent autologous reconstruction, 171 (26.9%) underwent implant-based reconstruction, and 214 (33.7%) unspecified. IBR utilization increased from 6.3% to 10.1% from 2004 to 2016 at a 4% average annual growth rate (P < 0.001). Median follow-up was 43 and 45 months for IBR and non-reconstructed patients, respectively (P = 0.29). On Cox multivariable analysis, IBR was associated with improved OS (HR 0.63, 95% CI 0.44-0.90, P = 0.01), but this association was not significant on IPW analysis (P = 0.06). In PSM cohorts, this association remained significant (HR 0.60, 95% CI 0.40-0.92, P = 0.02). Margin status, time to PMRT, 30-day readmission, and 30-/90-day mortality did not differ between groups (all P > 0.05).

conclusionAlthough not endorsed by national guidelines, IBR is increasing among IBC patients; however, more granular data are needed to determine oncologic safety.
