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

purposeWe studied the sleep macroarchitecture with polysomnography (PSG) in drug naïve patients with Parkinson's disease (PD) and reassessed them following treatment with levodopa. MATERIALS AND

methodsThis prospective hospital-based study included 15 patients with PD (age: 59 ± 11.2 years, duration of PD: 11.8 ± 12.3 months; and male: female (M:F) = 11:4). They were assessed for demography, phenotype, modified Hoehn and Yahr staging (H & Y); Schwab and England and Activities of Daily Living (S and E ADL) Scale; and Unified PDRating Scale (UPDRS). Sleep was assessed using Epworth Sleepiness Scale (ESS), Pittsburgh Sleep Quality Index (PSQI), and National Institute of Mental Health and Neurosciences (NIMHANS) comprehensive sleep disorder questionnaire. They underwent overnight PSG at baseline and after13.3 ± 5.7 months of levodopa (440 mg/day).

resultsPatients with PD had responded to levodopa as indicated by the significant improvement in UPDRS motor score in ON state compared to OFF state. Nocturnal sleep quality indices did not vary significantly, but the excessive daytime somnolence improved (P = 0.04) with levodopa. Sleep efficiency (P = 0.65), latency to sleep onset (P = 0.19), latency to stage 1 (P = 0.12), and duration of stage 1 (P = 0.55) had increased. Duration of 'awake in bed' (P = 0.24), slow wave sleep (P = 0.29), and rapid eye movement (REM) sleep (P = 0.24) decreased with treatment. Periodic leg movements (PLMs) had reduced (P = 0.68) and mean oxygen saturation during sleep improved (P = 0.002). Surprisingly, snore index (P < 0.03) during sleep had increased with levodopa.

conclusionsSleep alterations in PD occur even in early stages due to the disease process. There was improvement in most of the parameters of sleep macroarchitecture with levodopa.
