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
backgroundThis study aimed to retrospectively evaluate the effectiveness of hydroxyapatite-coated (HA-coated) implants and other caput-collum implants in preventing cut-out observed in treatment with proximal femoral nail (PFN) of intertrochanteric femur fractures in elderly patients.
methodsA total of 98 consecutive patients (56 males and 42 females; mean age: 79.42 (61-115) years) treated with three differ-ent PFNs for intertrochanteric femoral fractures were retrospectively examined. The mean of the follow-up period was 7.87 (4-48) months. It was used a threaded lag screw in 40 patients, an HA-coated helical blade in 28 patients and a non-coated helical blade in 30 patients for PFN. The reduction quality, fracture type, and radiological outcomes among all groups were evaluated.
resultsUnstable type was seen in 50 (52.1%) patients according to AO Foundation/Orthopedic Trauma Association fracture classi-fication. An acceptable-good reduction quality was seen in 87 (88.8%) of all patients. The average of tip-apex distance (TAD) value was 27.61 mm, calcar-referenced TAD (CalTAD) value was 28.72 mm, caput-collum diaphyseal angle was 128,° Parker's anteroposterior ratio was 46.36%, and Parker's lateral ratio was 46.82%. The best suitable implant position was observed in 49 (50%) patients. Cut-out was observed in 7 (7.14%) patients, and secondary varus displacement of more than 10° was observed in 12 (12.24%) patients. Correlation analysis and multivariate logistic regression analysis showed a significant difference between HA-coated and other implants in cut-out. Furthermore, implant type was the strongest predictive factor for cut-out complications in the multivariate logistic regression analysis.
conclusionHA-coated implants may reduce the long-term cut-out risk due to increased osteointegration and bone ingrowth in elderly patients with intertrochanteric femoral fractures with poor bone quality. However, this alone is not enough; a suitable screw position, optimal TAD values, and excellent reduction quality are other important factors.
