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

backgroundObstetric cholestasis (OC) is a serious problem in pregnancy. It affects about 4500 women per year in the UK. Affected women develop itching and occasionally jaundice. More importantly, the condition is associated with premature delivery, fetal distress and is believed to be an important cause of stillbirth. However, even now, there is no clear evidence as to whether the most popular treatment, a drug called ursodeoxycholic acid is beneficial to the baby, or even if it is safe in pregnancy. Nor do we know whether planned early delivery of the baby at 37-38 weeks, another popular treatment, does more good than harm. A randomised trial to evaluate both ursodeoxycholic acid and timed delivery is needed but will be complicated and expensive. We plan a preliminary study, Pilot study for a trial of ursodeoxycholic acid and/or early delivery for obstetric cholestasis (Acronym PITCH- Pregnancy Intervention Trial in Cholestasis) trial, to evaluate the feasibility of a larger trial. The trial is funded by the NHS Research for Patient Benefit (RfPB) Programme.

methodsPITCH is a multi-centre, double blinded, randomised, controlled, factorial design trial. The trial is being run in six UK centres and women with obstetric cholestasis will be recruited for eighteen months. In this pilot trial we aim to collect data to finalize the design for the main trial. This will include measuring trial recruitment rate, including recruitment to each factorial comparison separately. We will also measure the spectrum of disease among recruits and non-recruits and compliance with the four possible treatment allocations. We will use these data to design the main trial. DISCUSSION: The ultimate aim of the main trial is to enable clinicians to manage this condition more effectively. If it transpires that ursodeoxycholic acid and early delivery are both safe and effective then steps will be taken to ensure that all women with OC who could benefit from them receives this treatment. Conversely, if one or both the treatments turn out to be ineffective or even harmful, they will be stopped and researchers will work at developing other modes of treatment.
