Efficacy and safety of levothyroxine monotherapy in lowering the risk of cardiovascular disease in older adults with subclinical hypothyroidism: research protocols of a multicenter, open-label, randomized controlled trial.

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
objectiveThis multicenter, open-label, randomized controlled trial (RCT) aims to assess the efficacy and safety of levothyroxine monotherapy in lowering the risk of cardiovascular disease (CVD) in untreated older adults with subclinical hypothyroidism (SCH) who are diagnosed according to population-specific TSH reference values.
methodsA total of 254 patients with SCH who meet the diagnostic criteria will be recruited, and the baseline clinical data of the patients will be collected. Then, a total of 127 patients will be randomly divided into each of the treatment and control groups, and the treatment group will receive daily levothyroxine doses (Merck Euthyrox® levothyroxine 50 mcg tablet). Specifically, 50 µg of levothyroxine per day will be administered to patients in the treatment group (or 25 µg to patients with a body weight < 50 kg) for at least 48 weeks to maintain thyroid-stimulating hormone (TSH) levels within the normal range. The participants in the control group will be subjected only to thyroid status evaluation, and the results will be recorded. The participants will complete five visits before and after the start of the trial, and differences in the change in carotid intima-media thickness (CIMT), maximum mean change in plaque burden, and changes in lipid profiles, bone mineral densities, and incidences of fatal and nonfatal cardiovascular events between the initial visit and the last follow-up visit will be evaluated via vascular ultrasound. DISCUSSION: We will explicitly address whether levothyroxine replacement therapy provides cardiovascular benefits for older adults with subclinical hypothyroidism. CLINICAL
