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
objectiveAt present, the true sagittal alignment of the cervical spine is uncertain, resulting in no standard reference for subaxial cervical surgery. So, we aimed to explore the age difference of normal cervical sagittal alignment and to further investigate the mid-and long-term changes of sagittal alignment after subaxial cervical spine surgery. MATERIALS AND
methodsThis was a retrospective study and 1223 asymptomatic volunteers and 79 patients undergoing subaxial cervical spine surgery were retrospectively reviewed in total. Asymptomatic volunteers and patients were divided into six subgroups: 20-29, 30-39, 40-49, 50-59, 60-69 and ≥70 groups. The age difference and trend with age of cervical sagittal parameters of asymptomatic volunteers were assessed by cervical lateral radiography and analyzed by ANOVA test, and the regression equation of C2-7 Cobb was established via multiple linear regression. Based on the C2-7 Cobb regression equations of different ages, the theoretical value, deviation value, loss value of the C2-7 Cobb, and JOA recovery rate of patients were calculated, and the correlation among the loss value, deviation value of the C2-7 Cobb, and JOA recovery rate of the 79 patients was evaluated by Pearson correlation analysis.
resultsFor the asymptomatic volunteers, the C0-2 Cobb decreased gradually with increasing age. The C2-7 Cobb, C2-7 SVA, T1S, NT, and TIA increased gradually with increasing age. The CBVA fluctuated with increasing age. T1S demonstrated a moderate correlation with C2-7 Cobb (r = 0.60, p < 0.01); C0-2 Cobb, C2-7 SVA, CBVA, and TIA demonstrated a fair correlation with C2-7 Cobb (r = -0.30, -0.33, 0.41, 0.40, p < 0.01); age demonstrated a poor correlation with C2-7 Cobb (r = 0.19, p < 0.01). The regression equations of C2-7 Cobb were established using C0-2 Cobb, C2-7 SVA, CBVA, and T1S. For the patients with subaxial cervical spine surgery, the loss of C2-7 Cobb was moderately correlated with the deviation of C2-7 Cobb (r = 0.33, p < 0.01).
conclusionThe age difference of cervical sagittal alignment was obvious, and the C2-7 Cobb increased with age especially. The closer the postoperative C2-7 Cobb was to the theoretical value of corresponding age, the smaller the loss of correction angle was, and the better the mid- and long-term outcomes. The personalized sagittal reconstruction should be performed according to age difference for subaxial cervical spine surgery.
