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

backgroundIn the current society, infertility related to age has become a social problem. The in vitro fertilization (IVF) success rate in women with poor ovarian response (POR) is very low. Dandelion extract T-1 (DE-T1) is an effective component of the extract from the leaves and stems of Taraxacum officinale, which is one of the medicines used in some patients with POR, but its molecular mechanism remains unclear.

methodsFollowing IVF, ovarian granulosa cells (GCs) of sixty patients were extracted and divided into normal ovarian response (NOR) and POR groups. GCs were cultured in a dose-dependent and time-dependent manner with DE-T1, proliferation of GCs was determined by Cell Counting Kit-8 assay, and mRNA levels of insulin-like growth factor 1 receptor (IGF-1R), luteotropic hormone receptor (LHR), follicle-stimulating hormone receptor (FSHR), LHR, and CYP19A1 (aromatase) were determined by quantitative polymerase chain reaction. Progesterone and estradiol (E2) concentrations were determined by enzyme-linked immunosorbent assay.

resultsThe cell viability gradually increased with the progressive increase in the DE-T1 concentration. Compared with the control group (without DE-T1), the mRNA expressions of FSHR, LHR, IGF-1R, and CYP19A1 were upregulated after the addition of DE-T1, especially in the 2.5% DE-T1 group (P < 0.01). The expression of IGF-1R was upregulated approximately 25 times (24.97 ± 4.02 times) in the POR group with 2.5% DE-T1. E2 and progesterone levels increased with the increasing DE-T1 concentration. There were highly significant differences in the E2 and progesterone secretion between the NOR and POR groups (P < 0.01).

conclusionDE-T1 may promote steroid hormone synthesis by promoting GC proliferation and upregulating GC receptor expression, thereby improving ovarian endocrine function.
