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
Atraumatic bilateral osteonecrosis of the femoral head (ONFH) is a rare phenomenon whose etiology is not fully understood. In this report, we describe the case of a 75-year-old female patient who developed rapidly onset bilateral ONFH after intra-articular corticosteroid injections. She was treated with staged bilateral total hip arthroplasty. Several months post-operatively, she developed aseptic loosening of the left femoral implant and requiring revision of her femoral implant. The severity and distal extent of her osteonecrosis was not fully appreciated upon initial surgical management, likely increasing her risk of failure of femoral implant osseous integration. This case demonstrates that intra-articular corticosteroid injections can cause severe ONFH with extension into the proximal femur and fixation failure. Thus, the extent of osteonecrosis in the proximal femur may influence stem choice.
