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
Surgeon handedness may influence prosthetic alignment in conventional manual total knee arthroplasty (CM-TKA), but whether robotic assistance mitigates this effect remains unclear. This study investigated whether Mako robot-assisted TKA (MA-TKA) mitigates handedness-related discrepancies in alignment accuracy and perioperative outcomes. This retrospective cohort study included 1160 patients who underwent unilateral TKA performed by three experienced right-handed surgeons. Patients were divided into four groups based on surgical technique and operated side: MA-left (n = 84), MA-right (n = 92), CM-left (n = 453), and CM-right (n = 531). Operative duration, tourniquet time, hospital stay, blood loss, and radiographic parameters (mechanical tibiofemoral angle, mechanical lateral distal femoral angle, medial proximal tibial angle, lateral femoral component and lateral tibial component) were compared. Outliers were defined as ≥ 3° deviation from target values. Baseline characteristics were comparable across groups. MA-left surgery had the longest operative and tourniquet times, while MA-right surgery yielded the lowest blood loss. Both MA groups had significantly shorter hospital stays and lower blood loss than CM groups (P < 0.001). Radiographic accuracy was superior in MA groups, with no differences between MA-left and MA-right for any parameter. In CM groups, left-sided procedures showed significantly poorer alignment and higher outlier rates than right-sided procedures (P < 0.05). MA-TKA mitigates the negative impact of surgeon handedness on prosthetic alignment, achieving homogeneous accuracy regardless of operated side. Despite slightly longer operative times, MA-TKA reduces blood loss and shortens hospital stay, offering tangible clinical value.
