1 · What the graph read from it

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.

2 · The registry

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 clinical utility of postoperative radioiodine therapy in patients with low-risk differentiated thyroid cancer (DTC) remains a subject of ongoing debate. Although radioiodine has been widely employed to reduce the risk of recurrence, its necessity in low-risk populations is increasingly questioned, given the favorable outcomes observed with surgery alone. To address this issue, we conducted a meta-analysis exclusively based on randomized controlled trials (RCTs) to comprehensively evaluate the efficacy and safety of radioiodine therapy in this specific patient population. Methods: We systematically searched 6 databases for eligible phase 3 RCTs comparing surgery with or without radioiodine in patients with low-risk DTC. Primary outcomes included recurrence and recurrence-free survival (RFS); secondary outcomes included adverse events (AEs), structural events, and biological events. Risk ratios (RRs) or hazard ratios (HRs) with 95% confidence intervals (CIs) were pooled and analyzed. Results: Two phase 3 RCTs (the ESTIMABL2 and IoN trials), encompassing 1280 patients, were included. Compared to the non-radioiodine group, radioiodine therapy did not significantly reduce recurrence rates (RR: 0.78 [0.36-1.70], Conclusion: Radioiodine therapy did not confer significant benefits in reducing recurrence or improving RFS in patients with low-risk DTC after thyroidectomy, and the safety profiles were comparable between the two groups.
