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
Introduction: Unstable intertrochanteric fracture poses challenges in terms of obtaining stable fixation and good post-operative outcomes. There is a paucity of clinical data comparing the commonly used proximal femoral nail (PFN) and PFN anti-rotation (PFNA) implants, especially in relation to osteoporosis. The purpose of this study is to assess the comparative performance of PFN and PFNA fixation in the treatment of unstable femur intertrochanteric fractures. Materials and Methods: This prospective observational study was conducted to understand and analyze the advantages of PFNA over PFN in the management of unstable intertrochanteric fractures from May 2021 to October 2023 at the Department of Orthopaedics, Chettinad Hospital and Research Institute, Kelambakkam. Patients presenting with an unstable intertrochanteric fracture with Singh's Index grades 1, 2, and 3 were included. Boyd and Griffin classification types 2, 3, and 4 were included in the study. The patients were randomized into two types of implant groups. All patients were operated with a standard protocol. Patients were followed up for a minimum of 6 months and any complications were noted. A comparison of functional outcomes was done using the Modified Harris Hip Score. Statistical analysis was done using the unpaired t-test/Mann-Whitney U test and Chi-square test/Fisher's exact test. A P < 0.05 was considered significant. Results: Every follow-up period included a Harris Hip Score assessment. At 3 months, the average score of PFN was 71.9 (range 66-81) and at 6 months it was 77.86 (range 72-90). For PFNA, at 3 months, the average score was 74.87 (range 66-81), and at 6 months, it was 89.3 (range 76-94). The improvement was seen well in the PFNA group which is statistically significant (P = 0.023). The most prevalent fracture was a type 2 fracture. Conclusion: The results showed PFNA has better rotation stability with single screws and better functional outcomes in treating unstable intertrochanteric fractures when compared to PFN.
