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

contextThe effects of growth hormone deficiency (GHD) and GH replacement therapy (GHRT) on health-related physical fitness are still unclear.

objectiveThis work aimed to characterize the effects of GHD and GHRT on health-related physical fitness in children.

methodsWe enrolled 49 GHD children (aged 10.7 ± 1.9 years) and 46 controls (aged 11.8 ± 2.3 years). Both groups underwent baseline assessment of body composition, muscle strength, flexibility, cardiorespiratory fitness, insulin-like growth factor-1, metabolic equivalents (METs-min/wk), sitting time, and health-related quality of life (HRQoL). These parameters were reevaluated in GHD patients after 1-year GHRT.

resultsCompared to controls, GHD patients exhibited higher sitting time (3603.5 ± 1334.8 min/wk vs 3011.6 ± 1215.3 min/wk; P = .03), and waist-to-height ratio (WtHR) (0.50 ± 0.07 vs 0.45 ± 0.06; P = .001), reduced muscle strength (squat jump 13.88 ± 4.0 vs 15.7 ± 4.2 cm; P = .04; long jump 114.6 ± 25.8 vs 126.2 ± 29.6 cm; P = .04; counter-movement jump 13.7 ± 3.9 vs 16.4 ± 4.7 cm; P = .002), 6-minute walking distance (6MWD) (501.1 ± 69.3 vs 535.3 ± 65.6 m; P = .03), and maximal oxygen uptake (VO2max) (29.7 ± 4.7 vs 31.9 ± 4.6 mL/kg/min; P = .02). One-year GHRT led to reduced sitting time (3107.5 ± 1370.9 min/wk; P = .03), WtHR (0.45 ± 0.06; P = .02) and fat mass percentage (27.4 ± 5.4 vs 23.7 ± 5.8; P < .0001), increased METs-min/wk (2174.5 ± 1737.9 vs 2788.1 ± 2395.0; P = .05), fat-free mass (22.1 ± 7.6 vs 27.9 ± 9.4 kg; P < .0001), handgrip strength (11.1 ± 3.6 vs 15.4 ± 4.9 kg; P = .0001) squat jump (16.6 ± 4.7 cm; P = .01), long jump (129.6 ± 25.2 cm; P < .0001), countermovement jump (16.0 ± 4.3 cm; P = .003), 6MWD (540.5 ± 88.5 m; P = .01), VO2max (31.8 ± 5.1 mL/kg/min, P = .02), and physical (76.76 ± 16.42 vs 84.61 ± 11.63; P < .007) and psychosocial HRQoL scores (75.61 ± 15.12 vs 80.91 ± 11.12; P < .05).

conclusionGHRT exerts broad beneficial effects on health-related physical fitness and HRQoL in children with GHD.
