1 · What the graph read from it

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.

2 · The registry

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

purposeThe number of total knee arthroplasties (TKA) increased rapidly. In conjunction with higher implantation rates, periprosthetic femur fractures following TKA are also gradually increasing. Purpose of this study was to evaluate polyaxial locking plate treatment of periprosthetic femoral fractures with retained total knee replacement using polyaxial locking plates in regard to quality of life, functional outcome and complications.

methodsThe Study design is a single-center retrospective cohort analysis. Included were patients with periprosthetic supracondylar femoral fractures with a well-fixed knee prosthesis initially treated with NCB plate (Non-contact bridging plate, Zimmer Inc., Warsaw, IN). Primary outcome was measured including quality of life and functional status using the SMFA-D score (German short musculoskeletal function assessment questionnaire), the mortality rate and union rate. Formerly published SMFA-data presenting representative randomly chosen cross-sectional data from general population of the USA and Dutch population was used as historic control group.

resultsIn total, 45 patients with a mean age of 74 years were included (10 males; 35 females). Body mass index averaged 27.4 kg/m

conclusionBesides already highlighted limitations in range of motion, we quantified patient-related limitations in daily living. A large number of patients after surgery are not self-reliant mobile or on orthopedic aids. A high CCI was directly related to the mortality rate and can be used as a predictive factor for postoperative mortality.
