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
Background: Periacetabular osteotomy (PAO) is an established treatment for hip dysplasia and has been increasingly combined with concomitant hip arthroscopy to address additional intra-articular hip pathology. Heterotopic ossification (HO) is a complication of arthroscopic and open hip procedures. Nonsteroidal anti-inflammatory drugs (NSAIDs) have become an established form of HO prophylaxis, but their use may delay bone healing. Purpose: To examine the incidence of HO without NSAID prophylaxis in patients after PAO with concomitant hip arthroscopy and to evaluate the impact of other variables on the development of HO in these patients. Study Design: Case series; Level of evidence, 4. Methods: Of 243 hips that underwent PAO with concomitant hip arthroscopy by a single surgeon over 11 years, 182 met the study inclusion criteria. No patients were discharged on NSAIDs for HO prophylaxis, although most took up to 6 weeks of aspirin 81 mg as part of the prophylaxis protocol for deep venous thrombosis. Radiographic images at 2 weeks, 6 weeks, and 3 months postoperatively were reviewed and graded for HO using the Brooker classification. Patient characteristics and surgical variables were recorded. The chi-square and Results: The incidence of radiographic HO was 6.6% (12/182 hips). Nine hips were Brooker grade 1, 2 were grade 2, and 1 was grade 3. Four patients experienced clinical symptoms of HO- including pain and restricted motion. Only 1 patient required a return trip to the operating room for surgical excision. Male patients were significantly more likely to develop HO than female patients ( Conclusion: There was a low incidence of HO and symptomatic HO in patients who underwent PAO with concomitant hip arthroscopy without using NSAIDs for HO prophylaxis. HO was significantly more likely to develop in male patients. Given the potential risk of NSAID use on bony union, the low incidence found in this study may obviate the need for postoperative HO prophylaxis.
