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

This study investigates the influence of climate variables, specifically temperature and relative humidity, on the equilibrium moisture content (EMC) of wood-a critical quality parameter. Using data from 100 synoptic stations across Iran (1987-2019), we analyzed trends in temperature, humidity, and EMC through the Mann-Kendall and Sen's slope methods. Future projections (2020-2049) employed CMIP6 models-CanESM5, CanESM5-CanOE, CNRM-CM6-1, CNRM-ESM2-1, and IPSL-CM6A-LR-under SSP scenarios, with model selection based on RMSE, Scatter Index, and R². Scenarios SSP1-2.6, SSP2-4.5, and SSP5-8.5 were used to project future climatic conditions and corresponding EMC values. The CanESM5-CanOE model exhibits the lowest monthly relative humidity estimation errors in Iran, with errors ranging from 10.1% to 15.0% across different climate zones. Increasing EMC is most frequent under SSP1-2.6 (20%-92% of stations) and SSP5-8.5 (34%-100%). Decreasing trends are significant under SSP2-6.5 (66%-100%) and SSP5-8.5 (45%-88%). Monthly variations: -4.74% to + 3.71%; seasonal: -2.87% to + 2.45%; annual: -1.17% to + 1.00%. Significantly decreasing EMC trends are under SSP2-6.5, increasing trends under SSP5-8.5. Over a 30-year span, EMC varied from 0.06 to 0.62% in winter, from - 1.14 to -1.23% in spring, from - 0.84 to -0.89% in summer, and from - 0.80 to -1.34% in autumn, with most changes being statistically significant. These findings suggest climate change will substantially impact on wood EMC, underscoring the importance of revising future EMC standards accordingly.
