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
Objective: To evaluate the therapeutic effects of microwave ablation (MWA) versus surgery in treating low-risk papillary thyroid microcarcinoma (PTMC) and to assess recurrence-free survival (RFS) in patients with and without the BRAFV600E mutation. Methods: Between August 2016 and September 2022, 158 patients diagnosed with low-risk PTMC treated with MWA and 288 patients who underwent surgical treatment were retrospectively analyzed. All patients were followed-up for over a year. Local tumor progression (LTP), RFS and adverse events associated with both treatments were monitored. Following propensity score matching (PSM), comparisons were made regarding LTP, RFS, complications and treatment variables. Results: Prior to matching, MWA patients were younger than those in the surgery group (38 (30.75, 47) vs 43 (34, 50.75), P = 0.000). Tumors treated with MWA had smaller maximum diameters (5.7 (4.6, 7.0) vs 6.9 (5.8, 8.6), P = 0.000) and volumes (70.7 (35.2, 120.9) vs 122.0 (63.9, 228.8), P = 0.000). After 1:1 PSM, each group contained 141 patients with comparable baseline characteristics. During the follow-up, LTP developed in nine patients: six in the MWA group and three in the surgery group. There were no cases of distant metastasis or cancer-related deaths. Adjusting for age, sex, tumor location and largest diameter, there was no significant association between treatment modality and recurrence (HR = 3.75, 95% CI: 0.94-14.98, P = 0.062). There were no significant differences in RFS between patients with and without the BRAFV600E mutation in both groups (P = 0.45 and 0.74, respectively). Furthermore, the incidence of complications was comparable between treatments. Conclusion: Both MWA and surgical treatment offer similar efficacy and safety profiles for managing low-risk PTMC. MWA may represent a viable alternative to conventional surgical approaches, especially for patients harboring the BRAFV600E mutation.
