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
The application of 3D printing patient specific instrumentation model in total knee arthroplasty was explored to improve the operative accuracy and safety of artificial total knee arthroplasty. In this study, a total of 52 patients who need knee replacement were selected as the study objects, and 52 patients were divided into experimental group and control group. First, the femoral mechanical-anatomical angle (FMAA), lateral femoral angle (LFA), hip-knee-ankle angle (HKA), femorotibial angle (FTA) of research objects in both groups were measured. Then, the blood loss during the operations, drainage volume after operations, total blood loss, hidden blood loss, and hemoglobin decrease of the experiment group and the control group were measured and calculated. Finally, the postoperative outcomes of patients who underwent total knee arthroplasty were evaluated. The results showed that before the operations, in the PSI group, the femoral mechanical-anatomical angle (FMAA) was (6.9 ± 2.4)°, the lateral femoral angle (LFA) was (82.4 ± 1.6)°, the hip-knee-ankle angle (HKA) was (166.4 ± 1.4)°, and the femorotibial angle (FTA) was (179.5 ± 7.3)°. In the CON group, the FMAA was (5.8 ± 2.4)°, the LFA was (81.3 ± 2.1)°, the HKA was (169.5 ± 1.9)°, and the FTA was (185.4 ± 5.4)°. The differences in these data between the two groups were not statistically significant (P > 0.05). After the operations, in the PSI group, the total blood loss, the hidden blood loss, and the hemoglobin (Hb) decrease were respectively (420.2 ± 210.5), (240.5 ± 234.5), and (1.7 ± 0.9); in the CON group, the total blood loss, the hidden blood loss, and the Hb decrease were respectively (782.1 ± 340.4), (450.9 ± 352.6), and (2.9 ± 1.0). These data of both groups were statistically significant (P < 0.05). Therefore, it can be seen that the 3D printing patient specific instrumentation model can effectively simulate the lower limb coronal force line and was highly consistent of the preoperative software simulation plan. In addition, the random interviews of patients who underwent total knee arthroplasty showed that the knees of patients had recovered well. The application of 3D printing patient specific instrumentation model in artificial total knee arthroplasty can effectively improve the operative accuracy and safety, and the clinical therapeutic effects were significant.
