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

Purpose: To investigate the risk factors of increased hidden blood loss (HBL) after total hip arthroplasty (THA) for femoral neck fracture in elderly women and establish the nomogram prediction model for the guidance to reduce HBL in clinic. Patients and Methods: A total of 206 elderly female patients with femoral neck fracture who underwent THA in Northern Jiangsu People's Hospital from January 2019 to November 2021 were included. The demographic and relevant clinical information of the patients were collected. Pearson, independent sample Results: HBL was 626 ± 400 mL, accounting for 72.8% ± 18.4% of the perioperative total blood loss (TBL) (799 ± 411 mL), while blood loss of HGB was 15.1±10.4 g/L. Multiple linear regression analysis showed that HBL was associated with lower age (regression coefficient = -9.271, P = 0.010), operative time (regression coefficient = 2.653, P = 0.004), preoperative blood calcium (<2.25 mmol/L) (regression coefficient = 232.492, P < 0.001), hypertension (regression coefficient = 150.352, P = 0.002) and osteoporosis (regression coefficient = 276.072, P < 0.001). R software was used to construct the nomogram prediction model and draw the ROC curve and calibration curve. The area under the curve (AUC) is 0.92 and the slope of calibration curve is close to 1. Conclusion: Based on the five independent risk factors including age, operative time, preoperative blood calcium, hypertension and osteoporosis, the nomogram can predict the risk of HBL after THA for femoral neck fracture in elderly women with favorable differentiation and accuracy.
