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
purposeBasicervical femoral neck fractures (BFNFs) are uncommon in the elderly but associated with higher postoperative complications compared to intertrochanteric fractures. Proximal femoral nail antirotation (PFNA) is one of the preferred surgical options for intertrochanteric fracture due to its minimal invasiveness, fewer complications, and better in postoperative functional outcomes. However, limited research addressed the outcomes and the risk factors for implant-related complications after using PFNA.
methodsThis retrospective study included 149 patients treated with PFNA fixation in a University hospital. Inclusion criteria were age over 65 years, BFNFs from low-energy trauma, prefracture ambulatory level as independent ambulation with or without gait aids, with available data and follow-up period of at least 1 year. Exclusion criteria included open fracture, pathological fracture, multiple or high-energy traumas, and open fractures. Implant-related complications was defined as nail breakage, peri-implant fracture, varus collapse, blade cut-out or cut-through, and excessive sliding (> 10 mm). Demographic, clinical, and radiographic data were collected and analyzed. Multivariate logistic regression analysis was used to identify the risk factors.
resultsOf the 149 patients (26 males, 123 females) with an average age of 81 ± 9 years. Seventeen patients (11.4%) had mechanical complication and 11 patietns (7.4%) had reoperation. Univariate analysis showed that BMI, ASA grade 4, diabetes, tip-apex distance (TAD), calcar-referenced TAD, neck shaft angle, lateral angulation, anteromedial cortical support (AMCS) reduction, and Chang reduction quality criteria were potential predictors. Following multivariate analysis, only BMI, ASA grade 4, lateral angulation and AMCS were significant risk factors for implant-related complication (p < 0.05 all).
conclusionThe elderly patients with BFNFs and treated with PFNA are generally safe with acceptable reoperation rate. However, the proper reduction technique using AMCS and lateral angulation are essential for successful outcomes. Moreover, the patients with high BMI and ASA grade 4 are significantly associated with implant failure and required special attention.
