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
Background: The correlation between the Miniaci angle and presurgical hip-knee-ankle (HKA) angle, weightbearing line (WBL) percentage, and changes in the HKA angle (ΔHKA angle) and WBL percentage (ΔWBL percentage) is significant in opening-wedge high tibial osteotomy (OWHTO). The conversion formulas that interrelate the Miniaci angle with pre-HKA angle (formula 1), pre-WBL percentage (formula 2), ΔHKA angle (formula 3), and ΔWBL percentage (formula 4) have been derived through the linear regression analysis. However, the accuracy of conversion formulas has not been validated. Purpose: To validate the precision of conversion formulas targeting various surgical objectives for OWHTO planning in the varus knee patient population. Study design: Cross-sectional study; Level of evidence, 3. Methods: A retrospective study of 155 lower limbs of 112 patients with medial unicompartmental knee osteoarthritis was conducted. A computer simulation of OWHTO was performed to calculate the Miniaci angle by delivering the WBL to the Fujisawa point (group 1), at 65% WBL percentage (group 2), and 4.5° of valgus (group 3). Spearman correlation and Bland-Altman analyses were conducted between the computer simulation and formula calculation. Results: Upon evaluating the widely accepted Fujisawa point as a postoperative target, all formula results demonstrated a strong correlation with computer simulation outcomes ( Conclusion: Formulas based on the presurgical HKA angle and WBL percentage showed perfect accuracy for measuring the Miniaci angle targeting the Fujisawa point. The formula based on ΔHKA angle achieved the best accuracy and may be a valuable tool for measuring the Miniaci angle in broader surgical targets.
