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: Femoral head specimens are often sent for histopathology after geriatric femoral neck fractures in patients with past history of malignancies. However, the cost-effectiveness of this practice is unclear and the clinical impact and effect on patient management has yet to be ascertained. Methods: This is a retrospective review of all femoral head histopathology specimens registered in our center from 2003 to 2023. Patients <65 years of age were excluded from the study. Patient demographics were analyzed. Clinical notes and radiographic information were retrieved for all cases with positive histopathological findings to delineate any history of (1) atraumatic fractures, (2) prodromal pain and (3) radiological suspicion of pathological fractures. Any changes in subsequent management were also identified and analyzed. Result: From the 1431 cases, the average age was 81.9 ± 7.91 years-old, with 986 females (68.9%). There has been a rising trend of femoral head biopsies over the past 20 years. Only 45 cases had a positive histological diagnosis (3.14%). Among which, 37 of them had radiological features of malignancy (82.2%). Thirty-five cases did not have a history of trauma prior to the fracture (77.8%) and 29 out of 44 cases had documented prodromal pain (64.4%). For the positive cases, just over half (26/45) experienced a change in the subsequent management plan. Majority of cases were managed by palliative intent with adjunctive radiotherapy or bisphosphonate therapy alone. Cost analysis showed the direct cost of pathological examination to be $395.78 USD per case, with an average of $12,585 per positive case. Only 1.8% of femoral neck biopsies were of clinical significance with change in management plans. Conclusion: There is a low positive yield of femoral head biopsies with minimal change in management. Clinical history and radiological features can guide clinicians on the need for femoral head histopathology examinations.
