Computer Navigation vs. Conventional Overlay Methods in Direct Anterior Total Hip Arthroplasty: A Single Surgeon Experience.
Article in Cureus, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundThe use of computer navigation (CN) is expanding in direct anterior (DA) total hip arthroplasty (THA). In this study, we investigated the use of a noninvasive, fluoroscopic-based, CN technology suite on operative outcomes in a single surgeon DA THA practice. HYPOTHESIS: Computer-navigated DA THA decreases leg length discrepancy (LLD) variation and fluoroscopic radiation dose without adding operative time compared to the traditional overlay (OL) technique.
methodsA retrospective review was performed on a total of 109 primary DA THA patients, with 58 in the CN and 51 in the OL group. Outcome metrics were postoperative LLD, radiation dose per case, and operative time. Statistical analysis was completed with Mann-Whitney U tests for differences between the means for LLD, radiation dose, and operative time.
resultsNo difference was observed in postoperative LLD between the CN (average: 1.8 mm) and OL (average: 1.9 mm) groups (p = 0.458). A significant reduction in average radiation dose (mGy) per case within the CN group (8.17 ± 6.09 mGy) compared to the OL group (13.17 ± 7.75 mGy) (p < 0.02) was observed. The average operative time in the CN group was 80 ± 18 minutes compared to 120 ± 32 minutes in the OL group (p < 0.01).
conclusionThere was no difference in LLD between the two groups. The addition of CN into a DA THA practice decreased both average radiation dose and operative time when compared to the standard OL technique.
