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

backgroundThe ways in which Mycobacterium tuberculosis (Mtb) infection affects host metabolism and its implications for disease pathogenesis remain poorly understood. Understanding how Mtb shapes the metabolic state of the host could lead to nutritional and host-directed therapies to improve TB outcomes.

methodsWe performed high-resolution metabolic and lipid profiling on male rhesus macaques infected with Mtb (n = 17). Serial plasma samples were analysed beginning at the time of infection and up to 15-16 weeks post infection. Observed host metabolic changes were examined in a cohort of Mtb-infected (TBI, positive QuantiFERON Gold [QFT]; n = 92) and Mtb-uninfected (TBU, negative QFT; n = 102) participants as well as those with pulmonary TB (PTB; n = 68).

findingsUsing principal component analysis, we found the greatest metabolic changes in NHPs occurred 15-16 weeks after experimental infection. Metabolic changes were characterised by declines in saturated, monounsaturated, and polyunsaturated long chain fatty acids (LCFAs) including linoleic acid, linolenic acid, docosahexaenoic acid, and palmitoleic acid. Humans with TBI also experienced significant declines in plasma concentrations of nearly all species of LCFAs 6 months after Mtb exposure. In participants with PTB, LCFAs were further depleted relative to those with TBI but gradually normalised six months post-TB treatment.

interpretationOur study shows the host metabolic response to infection with Mtb is characterised by the systemic depletion of host lipids, which is exacerbated in persons with PTB. Interventions that supplement host lipids should be tested to determine their impact on TB outcomes.
