Role of Regulatory Proteins Involved in Iron Homeostasis in Pulmonary Tuberculosis Patients and Their Household Contacts.

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
Early identification and treatment of active tuberculosis disease among high risk household contacts could limit new transmission and better clinical outcome, thus decreasing TB burden. Host iron homeostasis is an important yet underevaluated factor in pathophysiology of tuberculosis (TB). One such protein is hepcidin which internalizes ferroportin (membrane iron transporter), thus inhibiting iron export from macrophages which is utilised by bacteria leading to disease severity. Iron homeostasis markers were evaluated in 50 pulmonary tuberculosis patients (PTB) and their household contacts to assess their utility as biomarkers for TB development. Altered iron homeostasis with significantly lower haemoglobin levels despite optimum serum iron levels was observed in PTB compared to household contacts and healthy controls pointing towards anaemia of inflammation. Higher serum hepcidin with lower ferroportin expression and hence higher ferritin levels was seen in PTB compared to both household contacts and healthy controls due to IL-6 induced hepcidin production in TB. Transferrin levels were found to be significantly lower in PTB and household contacts as compared to healthy controls owing to higher ferritin levels in PTB group. Upon infection, regulation of iron absorption is disturbed via increased hepcidin levels leading to ferroportin internalization and thus inhibition of iron export from macrophages which may lead to favourable
