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

Thiamine (vitamin B1) is a sulfur-containing, water-soluble vitamin that plays an essential role in energy metabolism and the tricarboxylic acid cycle. There is an increased need for vitamin B1 (1-1.2 mg daily) during pregnancy and lactation. Hyperemesis during pregnancy can cause severe polyneuropathy (Wernicke's encephalopathy) as a result of thiamine deficiency. Thiamine deficiency has also been associated with beriberi. A number of atypical cases with reversible right heart failure and severe pulmonary hypertension have also been reported in non-pregnant individuals, but have never been reported in pregnancy. Here we present five such cases of thiamine deficiency with neurological and cardio-pulmonary manifestations.
