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

objectivesTo determine whether there are important differences in performance between group practices and singlehanded general practitioners and the extent to which any differences are explained by practice characteristics such as deprivation.

designCross sectional survey.

setting206 singlehanded practices and 606 partnerships in Trent region, United Kingdom.

methodComparison of process and outcome measures derived from routinely collected data on hospital admissions and target payments for singlehanded practices and partnerships. Multivariate analysis was used to adjust for the confounding effects of general practice characteristics-deprivation (Townsend score), percentage of Asian residents, percentage of black residents, proportion of men over 75 years, proportion of women over 75 years, rurality, presence of a female general practitioner, and vocational training status.

resultsDifferences in achievement of immunisation and cytology targets apparent on univariate analysis were not seen after adjustment for other general practice characteristics. Similarly, significant differences (>15%; P<0.01) for three types of hospital admission seen on univariate analysis were not present after adjustment for other practice characteristics.

conclusionsThis study provides no evidence that singlehanded general practitioners are underperforming clinically. Our results offer insight into the structural difference between the two types of practice and underline the importance of the effect of other practice characteristics on process and outcome measures.
