Effects of folic acid plus levothyroxine on serum homocysteine level in hypothyroidism.
Article in Caspian journal of internal medicine, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundRise in serum homocysteine level may be associated with higher prevalence of cardiovascular diseases in hypothyroidism. Levothyroxine can partly diminish serum homocysteine level. Folic acid participates in homocysteine metabolic cycle in the human body. The effect of concomitant administration of folic acid and levothyroxine on serum homocysteine level was evaluated in the present study.
methodsSixty patients with hypothyroidism participated in this double-blinded clinical trial study. They were divided into two equal groups; Group A received oral levothyroxine 50-100 µg daily. Group B took oral folic acid 1 mg on a daily basis in addition to levothyroxine with similar schedule to group A. The patients were followed up for two months. The serum homocysteine levels of these two groups were measured before and after the study. This study was registered in Iranian Registry of clinical trial (IRCT number: 201112077723N1).
resultsMean serum homocysteine level fell from 11.5±4.2 to 9.9±3.5 µmol/lit and from 11.2±3.1 to 6.9±1.9 µmol/lit in group A and B, respectively (p<0.001). The mean reduction in serum homocysteine levels were 1.6±1.2 µmol/lit and 4.3±1.4 µmol/lit in group A and B, respectively (p<0.001).
conclusionLevothyroxine can decrease serum homocysteine level partly; still its combination with folic acid empowers the effect. Combination therapy declines serum homocysteine level more successfully.
