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
introductionProximal femoral osteotomy (PFO) with locking compression plates (LCPs) is effective for treating developmental dysplasia of the hip (DDH) in children. However, plate insertion or removal has a risk of postoperative femoral fractures. The goal of this study was to identify and analyse the association between postoperative femoral fractures after PFO and potential risk factors for these fractures.
methodsSix patients with DDH and postoperative femoral fractures were retrospectively reviewed at our hospital from June 2014 to October 2020. There were 2 boys and 4 girls whose ages ranged from 2 to 8 years (mean 3 years and 8 months). The timing, circumstances, fracture location, and refixation method were recorded for all patients. Four patients sustained fractures after plate removal: 3 after a fall and 1 spontaneously. Moreover, 2 patients experienced fractures early postoperatively after open reduction and PFO. The mean follow-up time was 31.6 months (25-57 months).
resultsAfter 153 patients underwent open reduction and PFO at our institution, six (3.9%) experienced postoperative femoral fractures. In children who underwent implant removal, all fractures (n = 4/4) occurred at the osteotomy site, whereas in those with retained implants (n = 1/2), fractures occurred at the screw hole. Three fractures were treated with reduction under general anaesthesia and spica casting, and three were treated with ESIN.
conclusionsInjuries from PFO, prolonged immobilization, or LCPs can result in postoperative femoral fractures in children with DDH. After PFO, the implants should be removed when solid union is achieved at the osteotomy site. Moreover, high-intensity activity should not be permitted until moderate or extensive remodelling at the osteotomy site is confirmed after plate removal.
