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

purposeTo comprehensively investigate the associations of subclinical thyroid dysfunction with BMD and fractures at various sites.

methodsComprehensive electronic and manual searches of databases were systematically conducted to identify prospective cohort studies from the inception of the databases to May 2019. The summary results for fractures and BMDs at various sites were calculated by relative risks (RRs) and weighted mean differences (WMDs) with corresponding 95% confidence intervals (CIs) using the random-effects model.

resultsSeventeen prospective cohorts from 24 studies were identified and 313,557 individuals were recruited in a final analysis. The summary RR indicated that subclinical hyperthyroidism was associated with an increased risk of any fracture (RR, 1.17; 95% CI, 1.08-1.26; P < 0.001), hip fracture (RR, 1.27; 95% CI, 1.09-1.48; P = 0.003), spine fracture (RR, 1.97; 95% CI, 1.31-2.97; P = 0.001), and non-spine fracture (RR, 1.19; 95% CI, 1.04-1.37; P = 0.014). However, there were no significant associations of subclinical hypothyroidism with the risk of any fractures (P = 0.166), hip fracture (P = 0.068), spine fracture (P = 0.818), and non-spine fracture (P = 0.277). Finally, subclinical hyperthyroidism was associated with lower distal forearm BMD in women, and ultradistal forearm BMD in both men and women, whereas subclinical hypothyroidism was associated with higher femur neck BMD in women.

conclusionSubclinical hyperthyroidism could induce additional risk on fractures at any, hip, spine, and non-spine, whereas subclinical hypothyroidism did not have any impact on fractures. Moreover, BMD at the lower distal and ultradistal forearms might be affected by subclinical hyperthyroidism, and higher femur neck BMD could be affected by subclinical hypothyroidism.
