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.
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
purposeGestational diabetes mellitus (GDM) is associated with an increased risk for maternal and fetal complications. Patients with GDM have an increased cardiovascular risk in later life. The aim of this study was to investigate cardiac autonomic nervous system (ANS) function at rest and during exercise in women with GDM vs. women with uncomplicated pregnancies.
methodsThirty-six normotensive pregnant women (21 with GDM and 15 age- and parity-matched women with an uncomplicated pregnancy) were enrolled in this case-control study. Continuous beat-by-beat blood pressure (BP) measurements were recorded during rest, intermittent handgrip exercise, and recovery (via photoplethysmography, Finapres®). Heart rate variability (HRV) (Kubios®) was used for the assessment of autonomic nervous system function.
resultsThe groups were similar in age, gestational week, and handgrip strength. At rest, no differences in HRV indices [root mean square of successive differences (RMSSD), standard deviation Poincaré plot 1, and 2 (SD1, SD2), SD2/SD1 ratio] were detected between women with GDM and women with an uncomplicated pregnancy. However, during exercise, a different pattern in the HRV responses was detected: in the control group, RMSSD and SD1 (indices of parasympathetic function) significantly decreased (p < 0.001) during handgrip exercise and returned to baseline during recovery. In contrast, in GDM, the above HRV indices remained unaltered throughout the protocol.
conclusionNormotensive women with GDM present impaired parasympathetic system ability to adapt to an exercise stimulus, as suggested by the blunted sensitivity in RMSSD and SD1. This finding suggests early alterations in ANS may exist in women with GDM, even when no differences are detected in resting conditions.
