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

introductionHemiarthroplasty is considered to be the treatment of choice for femoral neck fractures in elderly, however there is no consensus to support the choice between unipolar or bipolar hemiarthroplasty. Several studies found that patients with bipolar hemiarthroplasty had a better outcome of pain, a higher rate of return to the pre-injury state, and a greater range of hip motion. Some studies have demonstrated equal hip functional outcome between unipolar and bipolar hemiarthroplasty, but unipolar hemiarthroplasty was favoured due to its lower cost. The purpose of this study was to compare the functional and radiological outcome of cemented unipolar vs modular bipolar hemiarthroplasty in displaced femoral neck fracture in elderly patient population.

methodsIt is a prospective randomized study, with 44 patients in each group. Elderly Patients (>60 years of age) with traumatic displaced femoral neck fractures were included in the study. Cemented unipolar or modular bipolar hemiarthroplasty was performed in the respective patient groups using posterior or anterolateral approach. Functional outcome evaluation was done by Harris Hip Score and radiological outcome evaluation was done for acetabular erosion. The data was entered in MS EXCEL spread sheet and analysis was done using Statistical Package for Social Sciences (SPSS) version 20.0 (IBM, Chicago).

resultsThe mean age in the unipolar and bipolar group was 67.2 and 66.1 years respectively. The average follow-up period was 20.1 and 22.3 months in the unipolar and bipolar group respectively. Mean operating time was significantly more in the modular bipolar group (78.3 minutes) compared to the unipolar group (67.3 minutes). Two patients (4.5%) had acetabular erosion in each group. Mean Harris Hip score at 3 months follow-up was significantly higher (

conclusionFunctional outcome in terms of Harris Hip Score are better in the bipolar group at 3 months follow up but there was no significant difference in the functional outcome between the two groups at 6, 12 and 24 months follow up. The operative time for unipolar is lower and statistically significant compared to bipolar hemiarthroplasty of the hip.
