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

backgroundHip replacement is divided into total hip arthroplasty (THA) and hemiarthroplasty (HA); it is still controversial whether to choose THA or HA for femoral neck fractures (FNF). The goal of this study was to review relevant studies in order to determine the HA compared to THA for the treatment of FNF. PATIENTS AND

methodsUsing appropriate keywords, we identified relevant studies using PubMed, Cochrane, and Embase. Key pertinent sources in the literature were also reviewed, and all articles published through August 2019 were considered for inclusion. For each study, we assessed odds ratios (ORs), mean difference (MD), and 95% confidence interval (95% CI) to assess and synthesize outcomes.

resultsWe included 19 studies with a total of 413,140 patients in the HA group and 44973 in the THA group. The blood loss, surgery time, and dislocation were all significantly decreased in the HA group than the THA group. The length of hospital, pneumonia, and renal failure were significant increased in the HA group than THA group. There has no significant difference of complication, mortality, reoperation, infection, pulmonary embolism, and myocardial infarct between the two groups.

conclusionHA has favor in decrease blood loss and surgery time. THA has favor in decrease the length of hospital, the incidence of pneumonia and renal failure. For the selection of surgical methods for femoral neck fracture in the elderly, we should consider several aspects, such as the age of the patient, whether there is osteoporosis, the type of femoral neck fracture, the preoperative reduction situation, and the needs of the patient and his family for the postoperative situation.
