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

introductionPreliminary studies have established the elevated plasma total Homocysteine (tHcy) levels as a risk factor for Chronic Obstructive Pulmonary Disease (COPD). However, studies describing plasma tHcy levels and their relationship to folic acid supplementation and Forced Expiratory Volume in 1 Second (FEV1) status in COPD patients are still lacking.

aimWe investigated the role of hyperhomocysteinemia in COPD and then prospectively examined the relationship between plasma tHcy concentration and effect of folic acid supplementation on FEV1 status in COPD patients. MATERIALS AND

methodsThis was a prospective case-control study with 50 clinically stable patients of COPD attending the chest clinic of the hospital and 30 healthy controls. The study was done at Maulana Azad Medical College and associated Lok Nayak Hospital, New Delhi, India, from August 2011 to February 2013. Plasma levels of Hcy were measured by Enzyme Linked Immuno-Sorbent Assay (ELISA) method. All the subjects were given folic acid therapy (5mg daily) for six weeks duration and were followed up. Repeat plasma Hcy and FEV1 were measured after six weeks.

resultsCOPD patients had higher baseline plasma tHcy concentration than controls (Mean: 27.42±23.89μmol/L, versus 15.21±15.71μmol/L, p<0.001) and COPD was associated with higher tHcy concentrations also after adjusting for smoking, and age. The mean BMI of the patients was 21.36±4.26kg/m

conclusionCOPD patients seem to have a poor folic acid status and as a consequence high tHcy. Also, folic acid supplementation has shown decreased plasma tHcy concentrations, but not necessarily significant change in FEV1.
