Refractory Tibial Insufficiency Fracture Nonunion Healed with Parathyroid Hormone Level Correction: A Case Report.
Article in Journal of orthopaedic case reports, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionInsufficiency fractures are uncommon injuries, but may occur in the lower extremity due to repetitive stress on abnormal bone tissue. Management of these injuries may include weight bearing restrictions, bracing, or even surgical intervention. In addition, a proper metabolic healing environment is required to encourage healthy bone growth following an injury. CASE PRESENTATION: This case report discusses a patient who underwent surgical repair of a closed nondisplaced proximal tibia insufficiency fracture. Several reoperations were required due to hardware failure and bone resorption following operative nonunion repair. It was determined that her elevated PTH due to end-stage renal disease (ESRD) likely inhibited bone regeneration during the course of her treatment. A successful kidney transplant rapidly normalized the patient's PTH levels and permitted bony healing of her tibial stress fracture.
conclusionSeveral studies have demonstrated a relationship between metabolic abnormalities and fracture healing. We are the first to present a case where bony union in an ESRD patient with secondary hyperparathyroidism was only achieved following a kidney transplant. Surgeons should be cognizant of the effect that metabolic abnormalities may have in the development of insufficiency fractures and subsequently achieving bony union following such fractures.
