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

objectivesTo assess the impact of preoperative MRI on long-term survival outcomes in women with ductal carcinoma in situ (DCIS). MATERIALS AND

methodsThis retrospective study included women diagnosed with DCIS between January 2007 and December 2016. Propensity scores based on 25 demographic and clinicopathologic covariates were used to generate an overlap-weighted cohort, balancing patient groups according to MRI use. Recurrence-free survival (RFS) and overall survival (OS) were compared using Kaplan-Meier estimates with log-rank test and Cox proportional hazards models.

resultsAmong 1003 eligible women (mean age, 48.6 years ± 9.4 [SD]), 624 (62.2%) underwent MRI. During a median follow-up of 9.5 years, 122 (12%) experienced recurrence, including 75 (61%) invasive events. The 15-year recurrence rates did not differ between the MRI and no-MRI groups (27% vs 23%; p = 0.77). Preoperative MRI was not associated with recurrence in the overlap-weighted cohort (hazard ratio (HR), 0.88 [95% CI: 0.60, 1.30]; p = 0.53). The 15-year overall mortality rate was 7% in both groups (p = 0.93), and preoperative MRI was not associated with overall mortality in the overlap-weighted cohort (HR, 1.21 [95% CI: 0.55, 2.66]; p = 0.64). Preoperative MRI was not an independent factor for RFS (HR, 0.99 [95% CI: 0.71, 1.39]; p = 0.95) or OS (HR, 1.11 [95% CI: 0.52, 2.37]; p = 0.78).

conclusionPreoperative breast MRI was not associated with improved RFS or OS among women with DCIS. KEY POINTS: Question The impact of preoperative MRI on long-term outcomes in women with ductal carcinoma in situ (DCIS) remains uncertain. Findings In this retrospective propensity score-weighted analysis, preoperative breast MRI was not associated with improved recurrence-free survival or overall survival in women with DCIS. Clinical relevance Routine preoperative MRI may not improve long-term outcomes in DCIS. Prospective multicenter studies are warranted to identify subgroups that may derive meaningful survival benefits.
