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
The adipose tissue (AT) surrounding breast cancer (BC) plays a pivotal role in cancer progression and represents an optimal source for new biomarker discovery. The aim of this work was to investigate whether specific AT factors may have prognostic value in estrogen receptor-positive (ER+) BC. Proteoglycan Versican (VCAN), Insulin-like Growth Factor 1 (IGF1), Reticulon 4B (RTN4), chemokines CCL5 (also known as RANTES) and interleukin 8 (IL-8) are expressed in AT and may play important roles in BC progression. Peritumoral AT and tumoral biopsies were obtained from patients with ER+ BC (N = 23). AT specimens were collected also from healthy women (N = 17; CTRL-AT). The analysis of gene expression by qPCR revealed significantly higher mRNA levels of VCAN, IGF1, RTN4, and CCL5 in BC-AT compared to the CTRL-AT, and no difference in IL-8 mRNA levels. VCAN positively correlated with patient Body Mass Index (BMI) in BC-AT, while not in CTRL-AT. Moreover, VCAN and IGF1 positively correlated with RTN4 and negatively with CCL5. Interestingly, VCAN correlated with tumoral Ki67, while IGF1 with tumoral OCT4 that, in turn, correlated with tumoral Ki67 and patient BMI. Thus, peritumoral AT content of VCAN, and IGF1 are related to BC proliferation and aggressiveness.
