Regional Market Competition and the Use of Immediate Breast Reconstruction After Mastectomy.
Article in Annals of surgical oncology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundPrior work has shown that the competitiveness of the market in which hospitals operate is associated with use of surgical procedures. This study examined the association between regional market competition and use of breast reconstruction for women with breast cancer and ductal carcinoma in situ undergoing mastectomy.
methodsWomen who underwent mastectomy from 2010 to 2011 recorded in the National Inpatient Sample were selected. The competitive market environment for each hospital in which patients were treated was estimated using the Herfindahl-Hirschman Index. Multivariable models were developed to examine the association between regional market competition and breast reconstruction, with adjustment for other clinical, demographic, and structural variables.
resultsImmediate breast reconstruction was performed for 9902 (45%) of 22,011 women. The rate of immediate breast reconstruction was 34.5% at hospitals in non-competitive markets, 49% at hospitals in moderately competitive markets, and 56.4% at hospitals in highly competitive markets (P < 0.0001). In a multivariable model, women in moderately competitive markets were 24% (risk ratio [RR] 1.24; 95% confidence interval [CI] 1.10-1.41) more likely to undergo immediate breast reconstruction than women in noncompetitive markets, whereas those in competitive markets were 25% (RR 1.25; 95% CI 1.11-1.41) more likely to have reconstruction. Later year of treatment, higher census tract income level, and residence in an urban area were associated with an increased likelihood of reconstruction (P < 0.05 for all). In contrast, older age, non-white race, and non-commercial insurance were associated with a lower likelihood of reconstruction (P < 0.05 for all).
conclusionPatients who undergo mastectomy at hospitals in competitive markets are more likely to undergo immediate breast reconstruction.
