Subtrochanteric Femoral Insufficiency Fracture in Woman on Bisphosphonate Therapy for Glucocorticoid-Induced Osteoporosis.
Article in Radiology case reports, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
We present the case of an 85-year-old woman who sustained a subtrochanteric femoral shaft insufficiency fracture after receiving bisphosphonate therapy for osteoporosis. After more than 6 years of taking risedronate sodium (Actonel) and daily supplemental calcium carbonate and vitamin D, the patient developed right anterior thigh pain that was worse with weight-bearing. A small, pyramidal ridge of cortical bone was demonstrated by radiographs and CT along the antero-lateral subtrochanteric region of the right femoral shaft. On MRI, there was focally increased T2 signal in the adjacent bone marrow. Radionuclide bone scan showed moderately-intense, focally-increased uptake. The lesion was recognized as a potential stress riser for fracture; however, before a prophylactic intramedullary rod could be placed, the patient suffered a low-energy insufficiency fracture through the lesion. In the setting of bisphosphonate therapy for osteoporosis, a painful pyramidal projection of cortical bone in the subtrochanteric femoral shaft should be recognized as an impending insufficiency fracture and treated expeditiously.
