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

Although weight loss improves blood pressure (BP), its association with mortality remains unclear. In the Trials of Hypertension Prevention (TOHP), individuals aged 30-54 years with high normal BP were randomized to weight loss, usual care or other intervention over 18 months (TOHP I) or 3-4 years (TOHP II), with average 23-year mortality follow-up. We examined mortality and (a) randomized weight loss and (b) observed weight change among all with high baseline weight. Among 2964 randomized participants, 227 deaths occurred, with no intervention difference (hazard ratio (HR) = 0.97, 95% confidence interval (CI) = 0.75-1.26, P = 0.84). Among 3828 high-weight participants, weight change was directly related to mortality (HR = 1.14 per 5% change, 95% CI = 1.02-1.28, P = 0.019). During the trial 15% lost >5% (HR = 0.82), 29% lost 0-<=5% (HR = 0.94), 41% gained 0-<5% (reference), and 16% gained >5% (HR = 1.29) (P-trend = 0.046). This is consistent with a long-term beneficial effect of presumed intentional weight loss on mortality.
