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 assess race-specific incidence and prevalence rates for systemic lupus erythematosus (SLE) using 1991 National Census data and to ascertain the frequency of clinical/laboratory features of a geographically complete cohort of patients with SLE.

methodsMultiple methods of retrieval were used to ascertain SLE patients including screening request cards for immunology investigations. Patients were classified according to the revised ARA criteria. Multiple logistic regression analysis was used to study the effects of age at diagnosis on the frequency of clinical/laboratory SLE features.

resultsThe overall one year period prevalence rate for SLE was 24.7 (age adjusted, 95% CI: 20.7-28.8)/100,000. Highest rates were seen in Afro-Caribbeans (207 (111-302)/100,000), followed by Asians (48.8 (10.5-87.1)/100,000), and then Whites (20.3 (16.6-24.0)/100,000). The mean age at diagnosis of SLE was 40.9 years (range: 11-83) with a mean interval between first definite SLE symptom and diagnosis of 61 months (0-518). In 85% of patients the first definite lupus feature was musculoskeletal and/or cutaneous. In this SLE cohort renal disease (22%) was observed less commonly than in previous studies and the 'classic' butterfly rash was present in only 30% of patients. Malar rash, thrombocytopaenia, positive anti-dsDNA antibodies, hypocomplementaemia (C4), and positive IgG anticardiolipin antibodies were all seen less commonly with increasing age at diagnosis.

conclusionsA closer estimate of the true frequency of clinical/laboratory SLE manifestations is likely from this geographically complete cohort of patients compared with studies that may be skewed by referral patterns.
