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

The study aims to compare the clinical efficacy of core decompression (CD) and bone marrow mesenchymal stem cells (BMMSC) on the patients with osteonecrosis of the femoral head (ONFH). A detailed literature search of PubMed, MEDLINE and EMBASE, Springer, Elsevier Science Direct, Cochrane Library and Google scholar for all relevant papers published was performed. Pooled odds ratio (OR) or weighted mean differences (WMD) and 95% confidence interval (CI) were used to evaluate the clinical efficacy of CD and BMMSC with the clinical outcome on the patients with ONFH. A total of 219 hips in 4 studies were indentified in this current meta-analysis. The OR of 2 separate studies consisting of 115 hips (CD group 63 hips; BMMSC group 52 hips) of patients were pooled and suggested BMMSC group had significantly less number of progressed vascularized bone grafting events than CD group (OR = 0.11; 95% CI: 0.03~0.43; P < 0.01). In addition, WMD of other 2 separate studies consisting of 104 hips (CD group 52 hips; BMMSC group 52 hips) in patients were pooled, and significant differences (P < 0.01) in Harris Hip Score (HHS) were observed between these two treatment groups at the end of follow-up study, BMMSC group had significantly better clinical outcome than CD group (WMD = 8.69; 95% CI: 3.76~13.62; P < 0.01). BMMSC may perform a better therapeutic effect than CD on the patients with osteonecrosis of the femoral head.
