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

Objective This study aimed to investigate the association between low plasma Platelet-derived growth factor-BB (PDGF-BB) levels and oestradiol in Postmenopausal osteoporosis (PMOP). Methods This prospective study measured plasma PDGF-BB and oestradiol levels in outpatients who were admitted to our hospital. Participants were screened and then allocated to three groups: normal young women, postmenopausal control, and PMOP. Additionally, Sprague-Dawley rats underwent either sham surgery or bilateral ovariectomy (OVX), and were divided into the following groups: sham, OVX, OVX + oestradiol, and OVX + PDGF-BB. Plasma oestradiol and PDGF-BB levels were measured using commercially available ELISA kits. Results A total of 121 participants, including 69 normal young women, 28 patients with primary PMOP, and 24 age-matched postmenopausal women were enrolled. Plasma oestradiol and PDGF-BB levels were lower in postmenopausal women, especially in PMOP ( P < 0.01). Pearson correlations analysis showed that PDGF-BB levels were positively correlated with oestradiol levels and inversely correlated with age ( P < 0.01). The OVX rat model showed that oestradiol replacement increased plasma PDGF-BB levels, while PDGF-BB systematic treatment had no effect on plasma oestradiol levels. Conclusions Plasma PDGF-BB levels are maintained by oestrogen in normal young women and play a major role in PMOP.
