Similar risks of complications and reoperation rates in proximal femur megaprostheses for oncological and non-oncological indications.

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
purposeProximal femur megaprostheses (PFMPs) are used to manage large bone defects in both non-oncological indications (NOI) and oncological indications (OI). However, little is known about the comparative risks of reoperation and functional outcomes between these groups. This study aimed to evaluate the cumulative incidences of reoperation and functional results of PFMPs between NOI and OI.
methodsThis retrospective, monocentric cohort study included 109 implants between 2005 and 2020 (NOI, n = 42; OI, n = 67). Competing risk analysis was used to estimate and compare cumulative incidence of reoperation and complications, with death as a competing event. The Musculoskeletal Tumour Society Score (MSTS) was retrospectively assessed to compare functional outcomes.
resultsThe estimated cumulative incidence of reoperation at ten years did not statistically differ: 33.5% for NOI vs. 32.7% for OI (HR = 0.90, 95% CI (0.42-0.95), p = 0.791). The estimated cumulative incidence of complications at ten years did not statistically differ (HR = 1.50, 95%CI (0.80-2.80), p = 0.204). The MSTS score at ten years was significantly higher in the OI group (78.2% ± 19.5) compared to the NOI group (48.3% ± 10.9) (p = 0.012).
conclusionPFMPs for NOI demonstrate a comparable risk of reoperation to OI, but with lower long-term functional outcomes.
