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
objectiveIdentifying the risk factor for occurrence of trochanteric/femoral neck fractures has always been difficult and crucial for prognosis of the diseases. The goal of this study is to evaluate the difference of P1NP/β-CTX between trochanteric and femoral neck fractures and establish these two BTMs as independent risk factors for these two subtypes of hip fractures in the elderly.
methodsFollowing case-control study design, 83 elderly patients with fragile hip fractures from two tertiary hospitals recruited between February 2023 to August 2024 were assigned into intertrochanteric fracture group (42 cases) and femoral neck fracture group (41 cases). Baseline characteristics including age, sex, height, weight, BMI, and history of diabetes/Parkinson's disease were collected after admission. Besides, P1NP/β-CTX/PTH/25(OH)D blood tests and dual energy x-ray absorptiometry (DXA) were performed on all participants before surgical operation. The statistical significances of categorical variables and continuous variables were established through χ
resultsThe difference in P1NP between the trochanteric fracture group and femoral neck fracture groups is statistically significant. Specifically, patients with trochanteric fractures showed a markedly higher value of P1NP than those with femoral neck fractures (p = 0.044). However, no significant difference was observed for β-CTX between the two groups (p = 0.941). Furthermore, BMDs at trochanter and total hip regions in the trochanteric fracture group were significantly lower than those in the femoral neck fracture group (p = 0.028; p = 0.022). After multifactorial logistic regression, P1NP, weight, and female were stronger risk factors for trochanteric fracture (OR 0.969, 95% CI 0.948-0.990, p = 0.004; OR 0.531, 95% CI 0.284-0.992, p = 0.047; OR 0.082, 95% CI 0.008-0.837, p = 0.035), while height was found to be independently associated with femoral neck fracture (OR 1.715, 95% CI 1.023-2.874, p = 0.041).
conclusionsCompared with femoral neck fractures, P1NP was established as an independent risk factor for trochanteric fractures, suggesting the great potential of this BTM as a predictive indicator and postoperative complication monitor for trochanteric fractures.
