Comparison of perioperative hidden blood loss for intertrochanteric fractures in the elderly by different intramedullary fixations: A randomized controlled study protocol.
Article in Medicine, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It carries an expression of concern. Cited by 3 papers.
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
backgroundTill date only a few studies have reported the clinical outcomes of intraoperative hidden blood loss of intertrochanteric fracture in the old people treated with various intramedullary immobilizations. The aim of the trial is to investigate the best choice for treating intertrochanteric fractures, as well as the hidden blood loss among different intramedullary fixations.
methodsThis randomized, single-blind, superiority clinical trial was admitted by the Ethics Committee in our hospital (The 7th Medical Center of PLA, 20200602DM). The eligibility criteria were:Patients who met any of the following conditions would not be able to participate in the test: composite femoral fracture, under 65 years of ages, experience of femoral fractures, surgical contraindications, nonambulatory before the presenting injury, or presence of any other traumatic fractures. 120 participants with unstable intertrochanteric fractures, treated by Gammar nail, (n = 40), Proximal Femoral Nail Antirotation (n = 40) and Intertrochanteric Antegrade Nail (n = 40) instruments were enrolled in this research. The main outcome measures were total blood loss and hidden blood loss, which were evaluated based on the haematocrit change after the operation. The experimental data was analyzed and sorted out with SPSS program (ver.19; SPSS Inc., Chicago, IL).
resultsThis experiment had strict inclusive criteria and exclusive criteria and a well- regulated intervention.
conclusionsThe results of this trial will provide more evidence on which technique can better treat unstable intertrochanteric fracture.
trial registrationThis study protocol was registered in Research Registry (researchregistry5788).
