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

purposeSince 2008, guidelines recommend that patients with HER2-positive early breast cancer (BC) should receive adjuvant chemotherapy in combination with trastuzumab in Germany. However, recent studies highlight that a substantial share of patients do not receive trastuzumab. We investigate which patient characteristics are associated with a tumor board recommendation for trastuzumab in Breast Cancer Centers (BCC) certified by the German Cancer Society (DKG) and the German Society for Senology, and if the recommendation differs between BCCs. MATERIALS AND

methodsMulti-level modeling was performed using quality assurance data based on 3052 HER2-positive, operated patients with a first diagnosis of early BC treated between 2006 and 2019 in 17 BCCs in Germany to investigate whether trastuzumab recommendation varies with patient sex, age, and disease characteristics, as well as over time and across BCCs.

resultsTumor board recommendations for trastuzumab differ substantially between BCCs (intraclass correlation coefficient [ICC] null model: 0.11). Our final model (ICC 0.17, Akaike Information Criterion [AIC], 1328.0, R

conclusionIn certified BCCs in Germany, guideline concordant trastuzumab recommendation is increasing since 2006 (positive cohort effect). Recommendation of trastuzumab for HER2-positive BC patients in BCCs is significantly associated with patients' age and the recommendations for other additional therapy strategies, apart from surgery. The quality assurance data analyzed do not include potentially relevant confounders, such as socioeconomic status or comorbidities.
