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

objectiveTo evaluate the efficacy of lenvatinib in the treatment of radioiodine-refractory thyroid carcinoma.

backgroundThyroid carcinoma is one of the top ten carcinomas worldwide. Clinically, thyroid cancers are managed with resections and adjuvant therapy with radioiodine. However, radioiodine is not effective for radioiodine-refractory (RR) thyroid carcinoma in some patients. Lenvatinib is a multi-kinase inhibitor for the treatment of RR thyroid carcinoma. Several clinical trials showed its efficacy in prolonging progression-free survival (PFS) and overall survival (OS). DESIGN, PATIENTS AND MEASUREMENTS: A systematic search was done on databases (PubMed, Embase, MEDLINE, Cochrane) on 8 June 2020. Search keywords were lenvatinib, thyroid carcinoma and randomized controlled trials. Clinical trials fulfilling the SELECT protocol were selected to evaluate the efficacy of lenvatinib in terms of prolongation of PFS, OS and objective response rate (ORR). The risk ratio and distribution of grade 3 or above adverse events were documented.

resultsOf the 3997 patients of mean age 62.5 years in fifteen selected studies, lenvatinib is associated with prolonged PFS (hazard ratio 0.24, 95% CI, 0.19-0.31, p < .001) and OS (hazard ratio 0.65, 95% CI, 0.52-0.81, p < .001). Compared with placebo, the risk ratio of ORR and incidence of grade 3 or above adverse events are 35.41 (95% CI, 19.42-64.58, p < .001) and 8.25 (95% CI, 6.50-10.46, p < .001), respectively. Subgroup analysis shows that lenvatinib is effective for all patients with RR thyroid carcinoma, regardless of age, histological subtypes, radiological subtypes and mutation status.

conclusionLenvatinib is effective in the treatment of RR thyroid carcinoma. Close monitoring of serious adverse events is recommended.
