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

Insulin resistance (IR) is prevalent in women with polycystic ovary syndrome (PCOS). Improvement in insulin sensitivity remains one of the most effective treatment strategies for women with PCOS. This study aims to investigate the efficacy and potential mechanism of the combination therapy with metformin (DMBG) and sitagliptin (TECOS) in PCOS. To address this, insulin was used to treat rat ovarian granulosa cells to establish the cellular PCOS model. Insulin and human chorionic gonadotropin (HCG) were subcutaneously injected into SD rats to establish a rat model of hyperandrogenism with pathogenesis similar to PCOS. Our results showed that co-treatment with TECOS and DMBG attenuated the induced apoptosis and insulin resistance (IR) in PCOS model cells, and improved reproductive hormone disorders, ovarian polycystic changes, and IR of PCOS rats. Mechanistically, upregulation of H19 by H19-expressing lentiviruses enhanced efficacy of combination therapy. Furthermore, co-treatment with TECOS and DMBG induced H19 expression via suppressing the PI3K/AKT-DNMT1 pathway. Collectively, these findings demonstrate that combination treatment with TECOS and DMBG ameliorates PCOS with IR, at least partially, through upregulation of lncRNA H19.
