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

Acute porphyrias are rarely reported in Southeast Asia. They may be underdiagnosed due to their clinical mimicry and lack of awareness among physicians. There is a common cognitive bias to gravitate towards common conditions. In this case report, a 28-year-old woman, who presented with seizures, rhabdomyolysis hyponatraemia and altered mental state, was initially diagnosed as amphetamine overdose. She had presented 3 days prior with abdominal pain, treated for acute cystitis and discharged. On readmission for seizures a day later, she was extensively worked up for altered mental state. Despite normalisation of serum sodium concentration and control of her seizures, she remained unwell. Further investigations later confirmed a diagnosis of acute porphyria. The aim of this case report is to highlight the non-specific nature of presentation of acute porphyria and the importance of considering it as a differential diagnosis in cases of abdominal pain with neuropsychiatric features.
